What is the basis of Biblical credibility? Why should one believe the claims of the Bible verses the claims of any other book or individual claiming to have some kind of Divine message from God? Is the Christian required to blindly accept the Bible as true? – without any rational or logical basis for belief and in possible opposition to the significant weight of empirical evidence? Must the Christian faith subscribed to a form of fideism?
Personally, I don’t think so. The Bible itself cites empirical evidence over and over again as a basis for a rational faith in its metaphysical claims (to include fulfilled prophecy, credible eyewitness testimony, and accurate historical accounts). Along these lines, consider also an interesting discussion recently posed to this forum between myself, Dr. Paul Cameron (the one to whom I’m directly responding), George, and Pastor Bob Helm:
_____
Do you really know what you are signing on for with your acceptance or acquiescence to Sean’s views on scientific evidence or data which I described as non-sense?
GEORGE “Query: where is the specific evidence that supports a 6 day creation that you absolutely believe in?”
SEAN “As I’ve explained to you several times before, the weight of evidence for a literal creation week rests on the credibility of the Bible”
So according to this any scientific evidence for the reality of a 6 day creation is based on the credibility of the Bible.
The same is true of the credibility of any historical claim by anyone. A rational belief that something happened in history as described by some historian, such as Josephus for instance, is entirely based on the established credibility of the author (given that the event itself cannot be directly evaluated). How then is credibility established?
Further
“…and those elements that can be subjected to testing and potential falsification. Such elements include a recent creation of all life on this planet and a worldwide Noachian-style Flood.”
I am now confused – don’t the evidences for these evidences rest on the credibility of the Bible?
No. These Biblical claims are actually open to testing and potential falsification by comparing these claims with the evidences we have in the natural world. In other words, is there actual evidence of a recent worldwide Noachian-style Flood? Is there evidence of mass worldwide extinctions as a result of this Flood? Is there evidence for a recent arrival of all life on this planet? If the evidences are consistent with the Biblical claims, the Bible gains credibility. If they are inconsistent with the Biblical claims, the Bible loses credibility. It’s quite a simple and rational concept and it is used all the time.
As an example, consider the claims of the Book of Mormon regarding the origin of the American Indians as being one of the “lost tribes of Israel”. This claim can be tested, genetically, to see if it’s true. Clearly, this claim is effectively falsified. And therefore, for the rational person, this falsification of a key claim from the Book of Mormon significantly undermines its credibility with regard to those claims that cannot be directly tested.
What exactly are the testing procedure for the credibility of the bible if no historical criticism can be allowed?
Who said no historical criticism can be allowed? Historical criticism is perfectly fine – as long as it can be empirically supported with the weight of evidence. So far, however, Biblical critics have been on the losing end so many times its hardly worth counting. The Bible has be vindicated over and over and over again in the face of the “higher critics”… only adding further to its credibility.
Beyond that there are no cogent models of either the young life or the flood. Both of these have been rejected by the conventional science because there is no objective evidence for them short of religious assertion. Simple things like the Grand canyon as an evidence of a universal flood are rejected by geology. It is hard to conceive of how large eolian sandstone deposits (Coconino) could be placed within layers of clearly sedimentary deposits within a single flood.
The Grand Canyon wasn’t formed by the Flood. It was formed after the Flood by the catastrophic failure of a large inland lake and then subsequently by catastrophic failures of lava dams that suddenly released huge volumes of water.
.
As far as the Coconino Sandstone is concerned, there is good evidence that it was catastrophically deposited by water. It simply does not represent a desert or “eolian” environment at all.
“These claims can be tested in a potentially falsifiable manner.”
How exactly without critiquing the Bible which is viewed a source of scientific evidence or of proposing testable hypotheses?
The Bible should be critiqued in a critical manner before accepting it as credible regarding anything it has to say about history or God or other metaphysical “truths”. Fideistic faith, without any ability for testing or potential falsification, is worthless if one wishes to move beyond wishful thinking and a personal fantasy world.
“And, in my opinion, the Bible’s claims are supported by the significant weight of evidence that strongly suggests a very recent arrival of all life on this planet and a truly world wide Noachian Flood that produced much of the fossil record/geologic column.”
Now we get to it. Opinion can now be part of the “weight of evidence” which fits entirely with the Pitman model of science where personal anecdote is equivalent to the literature of science if it is based on some scientific process of personal hypothesis testing and conviction based on that method independent of any repository of knowledge, expertise or consensus.
Again, you defined “science” as the consensus of experts. That means, does it not, that it is impossible for anyone to come to any rational conclusion, via scientific methodologies of any kind, which are opposed to the consensus of mainstream scientists? If this really is your position, you just removed many famous scientists, who personally opposed the consensus of experts of their own day, from the realm of science.
Consensus means nothing if it is opposed to the clear weight of evidence – evidence which can be and often has been discovered by a single individual.
“Given this evidence, the Bible’s claim that God made it all in just one week of time is far more consistent and credible than are the neo-Darwinian claims for hundreds of millions of years of life existing and evolving from simple to complex on this planet.”
So now we have the completion of the circular argument. The evidence for the features of nature that support the fiat creation and the flood is the bible account and this evidence shows the credibility of the Bible and its account of the events.
The argument is not “circular” at all. Credibility is established by independent evidence, outside of the source itself. Once established, it is perfectly reasonable to cite the source as being most likely accurate with regard to those claims that cannot be directly tested. Tell me, why do you believe in the truth of the historical claim for the what happened during the Battle of Issus between Alexander the Great and Darius III in 333 B.C.?
Bob you have stated earlier;
“I believe that its sciences classes should ground students in an understanding of Neo-Darwinian evolution and the arguments for it. However, I believe that the arguments for ID/creationism should also be presented, and that the students should be taught how data can fit into this paradigm.”
If you accept the Pitman doctrine of science you will not only have to teach students about ID/creation and how “data can fit into this paradigm” but you will have to revise you ideas about data and will have to teach an entirely new way of understanding “weight of evidence” or data as being not just the peer reviewed literature of science but every hypothesis testing analysis, anecdote and piece of religious writing based on the Bible. Some in ID have accepted that as you will find if you look at what S Schiller has written in the thread on the blindingly obvious”. You will need to teach both theistic science; the science which is required to sustain ID arguments as Sean has done here and conventional science as it has been done for many many years which assumes only natural process a particular method of science and an accepted repository of scientific knowledge. The repository of knowledge that is the basis of modern western technology and medicine beloved and embrace by almost all students.
Do you want students to be taught these 2 methods of science and allowed to arbitrary choose what they would like according to their preconceived prejudices?
If our schools do not teach the rational basis for why the church disagrees with mainstream scientists, you undermine the very reason for having a church school – rather than adding yet another secular university, funded by the church, that promotes the usual philosophical Darwinian dogma.
Again, Darwinism isn’t science, but philosophy. The weight of actual empirical evidence in hand is completely opposed to the notion that random mutations and natural selection can create anything beyond very low levels of functional complexity – even if trillions of years of time were available. Your argument that some future discovery will come along to explain how it happened via some mindless mechanism isn’t scientific either – it is a philosophical, even a religious, argument that is based on wishful thinking, not the current weight of evidence that is actually in hand.

Plenty of data for the Coconino sandstone as water born.
The Coconino Sandstone, long claimed to be sand dunes turned to rock, are too fine-grained to be aeolian (wind-blown) sands, and cover too a vast an area (much of the Southwest: 100,000 square miles, with a volume 10,000 cubic miles) for this scenario to be plausible. The crossbedding could have been laid down as sand waves by deep ocean currents. The fossil trackways could have been made in shallow water and would have had to be buried suddenly to be preserved. All other layers in the canyon are indisputably water-deposited. To believe the Coconino was wind-deposited, the entire region would have had to be lifted above sea level without cracking or folding, yet the contact with the water-deposited Hermit Shale below it is flat and smooth. This indicates that deposition of the Coconino in the Grand Canyon began immediately after the Hermit formation, without 10 million years between them.

And they affirm the importance of Louis Agassiz’ dictum, “Study nature, not books.” It is very easy to quote some supposed authority on the Coconino Sandstone, but if a person really wants to understand that formation, it must be viewed firsthand. After all, the supposed authority could be mistaken! I wonder if our friend, Paul Cameron, has actually been to the Grand Canyon to see the Coconino Sandstone. I have, and what you have said about the flat contact line with the water-laid Hermit Shale is true. If the Coconino Sandstone had an eolian origin, that flat contact line with a water-laid deposit doesn’t make any sense.

Real science, the ability to think scientifically, was created and given to us as a gift of God. It therefore cannot but be in harmony with the written Word (rightly interpreted). This particular view was held by some of the most famous scientists in history – like Sir Isaac Newton for instance. Surely you cannot argue that these great men of science weren’t doing real science because of their arguments for discovering the works of a great and intelligent mind? – the works of God’s own hand? – that Nature Herself speaks of her Creator in a language that all can understand? – the language of science?

I am expert in only a small area of science and would accept in good faith consensus conclusions in others as closer to the truth than my facile understanding. This I have consistently done. If I want to disagree I would become familiar with the scientific literature clearly defined as the peer reviewed literature and that is what I expect of you. You claim the experts are wrong and I point you to what you have to address. It is totally irrelevant whether I am familiar with every piece of data since I am a very conventional scientist and physician who accepts both the accepted method and the canonical literature of medicine and science.

It is not incumbent on me to compensate for your lack of intellectual rigour by thinking for you. I unfortunately cannot make you honestly address that data or the accepted methodology of science.

View CommentI’ve read a bit about this topic over almost 20 years. However, I have not come across any argument, published or unpublished, which explains how random mutations and natural selection can tenably explain anything beyond very very low levels of functional complexity. And, now you seem to be telling me that you don’t personally know of any such published arguments or demonstrations either. After all, I’ve asked you to present such an argument or illustration or demonstration now for a couple of years and you’ve yet to present a single argument or paper along these lines – not one. You’ve told me to do PubMed searches and all, but you’ve failed to actually identify any single relevant paper or argument of any kind that addresses this fundamental question for Darwinism. What you seem to do is what everyone else seems to do – cite low level examples of evolution in action and then extrapolate to higher levels of evolution with the assumption of a linear relationship. When it is shown to you that your linear extrapolation models don’t represent actual reality (an exponential relationship), you have no explanation other than to try to argue that the concept of “levels of functional complexity” hasn’t been defined in literature (which is false) or to argue that some future discovery is sure to support your position (which isn’t scientific).
Are you saying that you simply accept the claims of experts without a personal understanding of how the Darwinian mechanism actually works at higher levels of functional complexity? – therefore it must work even if you personally do not understand how? If so, how is that any kind of challenge to anything I’ve presented? – besides to tell me that experts disagree with me for some reason that you personally don’t understand? Why do they disagree with me? You don’t seem to know. How is that helpful to me or anyone else who sincerely comes to you and asks you, personally, how random mutations and natural selection could possibly do what neo-Darwinians, like you, claim it did? If you don’t know the answer to this very basic question of Darwinism, why not just say so up front? Why even pretend that you know the answer when you really don’t?

1] Did the existing species of cotton and mustard arise from a kind taken on the ark or saved miraculously on log raft during the flood or were all the existing species taken on the ark?
2] Does the variation between the species with their extensive polyploidy look like evolution by “anything beyond very low levels of functional complexity”?
Is the total genome complex or not? Is gene duplication complex? Was the change to spinnable cotton “anything beyond very low levels of functional complexity”?

Can you given any example of novel systems the require more than 1000 specifically arranged amino acid residues? Please, name just one example and give a relevant quote and reference…
The genome is a collection of systems that function at both low and high levels of functional complexity. And, the aspects of the genome that require a minimum of more than 1000 specifically arranged residues were already there to begin with – within all gene pools.
In this light, consider that making a bunch of 3-letter words is not the same thing as making a single system of function that requires a minimum of 1000 characters to be in place and specifically arranged before it will work at all. That’s an entirely different problem and statistically unlikely, very unlikely, this side of trillions of years of time.
No. Gene duplication is very simple when you’re talking about functional complexity – and is fairly common. Gene duplication, by itself, does nothing more than produce more of the very same thing. And, it doesn’t improve the odds of finding something qualitatively new within sequence space at a given level of functional complexity.
If there were such a “high level” change, you would no doubt share it with us. So, what was this high-level change where something qualitatively new was evolved that required a minimum of more than 1000 specifically arranged residues to work?
When have I not posted your comments? And, when is asking for an actual example of a novel system evolving that requires more than 1000 specifically arranged amino acid residues an unreasonable request? If there is any interposing of a bunch of hocus-pocus here, it’s your argument that some future discoveries are bound to come along to support your Darwinian position – despite any current evidence that might appear to undermine your position.
What? I’ve been asking you to post a reference to real data over and over again which actually addresses my primary question to you regarding evolution at various levels of functional complexity. What you’ve done in the past is to post some PubMed search that returns hundreds of irrelevant papers that simply do not address this question at all.

View CommentPerhaps you could also look at the recent data on genomic sequencing of european pigs Asian boars and Tibetan wild boars. Again I will leave it to you to find the nature genetics paper and associated papers as I explained before. My questions
1] Were there Tibetan Boars, asian domestic pigs and european domestic pigs on the ark or did they all arise from a pig kind?
2] Do you agree with the Authors statement
“Tibetan wild boar has a higher proportion of lineage-specific genes (3,074 of 21,806, or 14.10%) compared with the 1,752 such genes in Duroc pig. Most of the genes specific to Tibetan wild boar (1,903 of 3,074, or 61.91%) have evidence of transcription (Supplementary Table 17), indicating that more new genes have arisen in Tibetan wild boar after the two breeds diverged from each other.”
3] Do you think that this represents “anything beyond very low levels of functional complexity” and that the adaption to high altitude in the Tibetan boars is insignificant and very very low level functional complexity?
pauluc(Quote)
View CommentDoes a useful degree of adaptation to high altitude in Tibetan Boars necessitate, at minimum, a qualitatively novel protein-based system that requires more than 1000 specifically arranged amino acid residues? If you think so, please do present the novel system that evolved and provide its minimum size/specificity requirement.
As a relevant aside, what is the minimum size requirement for the evolved antifreeze proteins in fish (and other organisms) that live in very cold environments? Do you see any higher level evolution here? – even close to the level of 1000 specifically arranged amino acid residues?

View CommentWhat does “molecular crowding” (the fact that a cell’s cytoplasm is densely packed with all kinds of molecules) have to do with the concept of discovering new types of beneficial proteins within “sequence space” at various levels of functional complexity? You do realize that sequence space is the space that contains all possible protein sequences of a given length? – and that sequence space has absolutely nothing to do with “molecular crowding”? In other words, the fact of molecular crowding doesn’t make it any easier to find the rare islands of novel beneficial sequences within the vast ocean of sequence space via random mutations.
For example, what is the sequence space size for sequence length of 100aa? It is 20^100 or 1e130 sequences. This is a larger number than all the atoms in the visible universe (~1e80 atoms). Clearly, the concept of “molecular crowding” has nothing to do with the concept of sequence space, which is an entirely different concept. The question is, what is the ratio of potentially beneficial vs. non-beneficial sequences within sequence space? In other words, how many random mutations would it take, on average, to an existing sequence within a genome to get it to mutate into another kind of beneficial sequence? That’s the real question.
Here’s a big clue for you: The density of potentially beneficial sequences within sequence space is very low, even at low levels of functional complexity. It is not “crowded” at all – not even close. There are always more non-beneficial sequences compared to potentially beneficial sequences in sequence space. And, it gets exponentially less and less crowded (with potentially beneficial sequences) with each step up ladder of functional complexity (i.e., with each increase in the minimum size and/or specificity requirements under consideration). This means, of course, that it is exponentially harder and harder to find, within a given span of time, novel islands of beneficial sequences within sequence space at higher and higher levels of functional complexity.
By all means everyone who is at all interested in the implications of these concepts should research the arguments carefully to see who is telling the truth here. Personal research is vital to know if what the “experts” are saying about Darwinism, specially regarding the creative ability of random mutations and natural selection, actually hold water… or even if someone like Dr. Paul Cameron even understands basic concepts like “sequence space” and how random mutations must randomly search through many junk sequences in sequence space before natural selection can do anything…

The absence of a record is of equal importance. Missing time results from rock units that have either eroded away or from periods of time in which no sediment was deposited. Such a gap in the temporal record is called an unconformity, and it’s the geologist’s business (and passion) to decipher what happened during it.

In fact, the Canyon’s rock layers are so full of temporal stratigraphic gaps that far more time is absent than is represented. In Annals of the Former World, John McPhee states, “If a gap of five hundred million years were the right five hundred million years, it could erase the Grand Canyon.”

Mysteriously, the rock layers that once existed between the two formations are missing. Perhaps they never even formed. Regardless of the cause, the space of that paper-thin contact represents an enormous amount of time unaccounted for, far greater than all the others, on the order of a billion years. That’s a quarter of the age of the Earth. Missing!

The Great Unconformity is not just found within the Grand Canyon but occurs in various locations within the Southwest. In fact, it can be found where ancient Laurentia’s Cambrian shelf is exposed and even globally where continental shores received deposition during the Cambrian. Back in New York State where I’m from, we have a Great Unconformity in the Adirondack lowlands in which the Middle Cambrian Potsdam Sandstone overlies a Middle Proterozoic Grenville gneissic-basement on Laurentia’s eastern shore.

View CommentThe basic math regarding sequence space is relatively simple. For instance, it is very easy to calculate the sizes of sequence space at various levels by simply taking the number of characters in the alphabet and raising that number by the power of the minimum size requirement for the sequence (i.e., the sequence space size needed to hold a 100aa protein is 20^100 = 1e130 sequences). It is also relatively easy to calculate the number of potentially beneficial sequences within sequence space. And, it isn’t that much harder to determine that the distribution of these beneficial sequences is essentially uniform throughout sequence space (although beneficial sequences are clustered into island groups). This information is enough to understand that exponentially greater amounts of time are required for random mutations of any kind to achieve anything beneficial within a higher level of functional complexity.
What do these articles have to do with finding novel beneficial islands within sequence space at various levels of functional complexity? Nothing. Nothing at all. They simply discuss various types of mutations and the differences between genes, but say nothing about the odds of finding a qualitatively novel island of beneficial sequences within a given level of sequence space at a particular level of functional complexity.
For example, here is the abstract of your NCBI paper:
First off, the function in question already existed in the gene pool to begin with, just at “low levels” of activity. Second, a simple increase in the copy number of the gene enhanced the very same type of function – easy. Nothing qualitatively new evolved here. Third, the function in question is an enzymatic function that doesn’t require more than a few hundred specifically arranged residues for minimum selectable activity.
No wonder this process is very rapid! Of course it would be since it is about as low-level as you can get. This is nothing like what it would take to actually find the minimum structural requirement needed to get a qualitatively novel function to work to at least some minimal selectable level of activity. And, this doesn’t even come close to the minimum requirement of 1000 specifically arranged amino acid residues.
Again, you continue to list off these very very low level examples of evolution in action like they mean something when it comes to explaining higher levels of evolution. That is simply a false assumption due to a lack of understanding of the basic math involved with the problem of sequence space…

I would consider more likely a population of ancestoral pigs since my view of population genetics is much more conventional. I do not think there was any particularly dramatic differences between them such as would be needed to travers your 1000 FSAAR limit. Admittedly there are unique genes in each species but most of these genes do have homologs in other mammalian species so could have evolved by simple loss of some genes in the different species of genes present in the presumed ancestor. Do you not agree?

View CommentAs you already know, I do believe that the evolution of a lot of simple genetic changes is in fact the reason for the genetic differences between different kinds of pigs or dog or cats, etc. I also believe that these simple changes can happen very rapidly.
So, I ask you, why did you present this example given that you already knew that it was yet another example of low-level evolution? Why not present just one example of higher level evolution in action or at least explain how such evolution is even likely, statistically, within a reasonable span of time? – like this side of trillions of years?
Now, I know you’re probably going to argue, yet again, that these lower level changes can add up over time to produce higher level changes. However, that’s just not true. Lower level changes remain lower level changes no matter how many of them might be realized. They simply do not add up over time to gain higher levels of functionality – i.e., qualitatively novel systems of function that requires a minimum of more than 1000 specifically arranged amino acid residues to work. The assumption that a bunch of lower level changes will eventually add up to produce more functionally complex systems is a false assumption that misunderstands the nature of sequence space and the statistical limitations involved with the problem.

Assuming that the rate of mutation in pigs and boar has remained constant over the last 4000 years since you say that the rate is the same now as then.
Looking at the available data published in the Li paper what are the data.
There are 3832 unique genes in boar
There are 1752 unique gene in the domestic pig
(Sup fig 12)
There are in 30 tibetan boar 8,390,501 SNP
there are in 15 chinese domestic pig 6,011,186 SNP
for a total of 9,492,123 SNP across the asian pigs. Among 103 pigs (30 tibetan boar, 52 domestic pigs and 21 wild boars) 14.64 million SNP
Supplementary table 33,35, sup methods)
In addition there more than 350,000 indels (Sup fig 11)
So from the 2 original animals in a sample of around 100 “pigs” indels have been introduced at nearly 100 per year, SNP have been introduced at 4160 per year and a new gene is introduce every 1-2 years.
Do you think these numbers will decrease if we add warthog into the mix?
You obviously can declare anything you want in terms mutation rates and how many SNP indels and genes were present in the 2 mythical pigs but how many can really be present in the original haplotypes. You have said before that copy number variation was not at all the basis for the genetic richness of the original 2.
Could you give me a reference that shows this mutation rate occurring now? If not I will have to conclude that your model is simply a faith based assertion which I am quite happy to accept. Postulate one miracle you may as well postulate as many as credibility requires.
If you do say it was done miraculously as I suspect Bill would do and Bob might, I would still say it is poor science according to the current well defined model of science but it is logically consistent and unassailable given the assumption of divine creation and divine dispersation and necessary recreation after the flood.

View CommentI see no reason to argue for a significant difference in past mutation rates as compared to today’s rates. Consider that the pig genome is similar in size to the human genome, ~3 billion bases (haploid). The two pigs on the Ark could easily have had a 0.3% difference in genome sequences to start with (with regard to SNPs). Also, in each family line novel SNPs are produced in each generation for each individual at a fairly high rate (up to 100 per individual per generation). And, the generation time for pigs is ~1 year. A comparison between hundreds of pigs from different family lines, even within the same breeding population of average size, would yield a huge number of SNPs in very short order. So, I don’t see why this is an appeal to “magic”?
As far as “unique genes” are concerned, much of this can be explained by a loss of genetic information by one population vs. the other after the split. This is one of the reasons for the “hybrid vitality” already mentioned. Producing such hybrids gives the hybrid offspring access to genes that are missing from each separate gene pool, but were originally available in the ancestral gene pool.
Of course, the production of novel alleles is also a factor. And, in an average population, any beneficial allelic variation would become fixed in relatively short order.
The differences in indels is interesting, but I see no need to invoke magic to explain a few hundred thousand indels in a comparison of hundreds of pigs – especially since muticharacter mutations are quite common as well and would already have existed within the first pair on the Ark to begin with. For example, there are thought to be thousands of conversion mutations per individual in each generation. Combine this with what is generally assumed to be a high rate of inversions/translocations, ~10 duplications/insertions/deletions (changing up to 20 times the number bases that point mutations change per generation), and >100 satellite mutations, and you have yourself a very high overall mutation rate that adds up to many thousands of nucleotide changes per individual per generation.

View CommentWhy don’t you explain to me the limiting factor or why “magic” would be needed to explain such low-level differences? – based on your expert understanding of population genetics? Is the mutation rate not high enough for you? How much higher does it have to be? After all, the mutation rate is so high that slowly-reproducing species are inevitably degenerating over time because the detrimental mutation rate is far far too high for natural selection to remotely compensate. Clearly then, allelic diversity can be rapidly achieved in very short order starting with a very small population. I really don’t think this is seriously debatable…
As far as I can tell, your only real argument was that such a population bottleneck would cause genetic meltdown and extinction. While this is often true today, it would not have been true much closer to Creation because there were far fewer detrimental mutations within the gene pools of all animals during the pre-Flood era. The level of detrimental mutations is the limiting factor here, not small population sizes or the actual mutation rates themselves.
In any case, what does any of this have to do with explaining how the Darwinian mechanism can produce anything at higher levels of functional complexity? Why repeat this red herring distraction yet again? – when you know that nothing beyond very low levels of functional complexity is involved here?

View CommentThanks you Sean. Now the subsequent question is why do you accept that boars and pig as genetically related by ancestory but not man and chimps. If you read the paper you will see that in fact there is greater genetic distance between pig and boar than between man and chimp. Loss of genes in the boar/pig is simply analogous to the y chromosome changes in human/chimp. Is this a 1000FSAAR or not?
If you accept that pig and boar arose by a sequence of small genetic changes occurring by gene selection in a gene puddle then you must logically also accept that man and chimp arose by small genetic changes as well. Particularly as you have not identified either in pig/boar or in human/chimp any differences fulfilling your 1000FSAAR barrier beyond simply hinting that Y chromosome changes must be such. I do not believe there is such a barrier. You do but have never even attempted to identify it with any sort of specificity.
pauluc(Quote)
View CommentI’m not talking about a loss of genes. I’m talking about a gain of a qualitatively novel protein-based function that requires a minimum of more than 1000 specifically arranged residues. Do you know of such a novel system or not? If so, please do present it here. Even if humans and chimps did have a common ancestor, how would this help you explain the evolution of higher level systems via RM/NS? – given that such has never been observed and is still statisically impossible this side of trillions of years of time? Such an argument has absolutely no explanatory power and is not scientific (being untestable in a potentially falsifiable manner).
Just for fun though, is there such a difference between humans and chimps? As I’ve explained to you before, there do seem to be such differences on a macro scale – to include structural brain differences that result in higher-level functional differences that require, not just specific 1000aa structures, but entire cellular structures that enable humans to do things that chimps cannot do – things like write books and speak in complex sentences, etc. These functional advantages are not based so much on novel genes, as previously explained, but on how the products of similar genes are used to make different types of structures and systems based on non-coding DNA (which is significantly different between humans and apes). And, as far as I’m aware, there are no such higher-level functional differences between boars and pigs. Consider also that boars and pigs can interbreed to produce viable offspring. This cannot happen between humans and chimps.
Again, you need to focus on functional systems, not genes. Do you have any example of any qualitatively novel system evolving that requires more than 1000 specifically arranged residues? You’ve yet to produce such an example or any mathematical argument that even allows for such an example. You seem to be trying to argue that it must happen because certain species simply must be related. Again, that’s not the same thing as producing an actual example or explaining how such evolution is statistically possible within the vastness of sequence space.
I have given you many specific examples of higher level systems. Yet again, the rotary bacterial flagellar motility system requires a minimum of over 5000 specifically arranged amino acid residues positions to be in place before this type of function will be realized. No system at this level of functional complexity or beyond has ever been shown to evolve nor are there any statistically tenable models on how this might be achieved via random mutations and function-based selection.
As far as this level of differences between pigs/boars, of course I am not aware of such – especially given that pigs and boars and interbreed to produce viable hybrids. As far as humans and chimps are concerned, more and more discoveries are coming to light that highlight fairly significant structural differences that are functionally relevant at a higher level of complexity. And, humans/chimps cannot interbreed. Why not? Well, for one thing the non-coding DNA is very different and is responsible for producing many of the structural/functional differences. And, for another thing, research carried out by scientists at the University of Oxford and the University of Chicago found that hotspot regions that determine the locations for genetic recombination during cellular meiosis in sexual reproduction showed “no overlap between humans and chimpanzees.” This was an “extraordinarily unexpected finding” given the assumed evolutionary relationship between humans and chimps.

A useful lie
10-10-2008 17:12 | Dr Richard Buggs
From 1964 to 2004, it was believed that humans are almost identical to apes at the genetic level. Ten years ago, we thought that the information coded in our DNA is 98.5% the same as that coded in chimpanzee DNA. This led some scientists to claim that humans are simply another species of chimpanzee. They argued that humans did not have a special place in the world, and that chimpanzees should have the same ’rights’ as humans.
Other scientists took a different view. They said that it is obvious that we are very different from chimpanzees in our appearance and way of life: if we are almost the same as chimpanzees in our DNA sequence, this simply means that DNA sequence is the wrong place to look in trying to understand what makes humans different. By this view, the 98.5% figure does not undermine the special place of humans. Instead it undermines the importance of genetics in thinking about what it means to be a human.
Fortunately (for both the status of human beings and the status of genetics) we now know that the 98.5% figure is very misleading. In 2005 scientists published a draft reading of the complete DNA sequence (genome) of a chimpanzee. When this is compared with the genome of a human, we find major differences.
To compare the two genomes, the first thing we must do is to line up the parts of each genome that are similar. When we do this alignment, we discover that only 2400 million of the human genome’s 3164.7 million ’letters’ align with the chimpanzee genome – that is, 76% of the human genome. Some scientists have argued that the 24% of the human genome that does not line up with the chimpanzee genome is useless ”junk DNA”. However, it now seems that this DNA could contain over 600 protein-coding genes, and also code for functional RNA molecules.
Looking closely at the chimpanzee-like 76% of the human genome, we find that to make an exact alignment, we often have to introduce artificial gaps in either the human or the chimp genome. These gaps give another 3% difference. So now we have a 73% similarity between the two genomes.
In the neatly aligned sequences we now find another form of difference, where a single ’letter’ is different between the human and chimp genomes. These provide another 1.23% difference between the two genomes. Thus, the percentage difference is now at around 72%.
We also find places where two pieces of human genome align with only one piece of chimp genome, or two pieces of chimp genome align with one piece of human genome. This ”copy number variation” causes another 2.7% difference between the two species. Therefore the total similarity of the genomes could be below 70%.
This figure does not take include differences in the organization of the two genomes. At present we cannot fully assess the difference in structure of the two genomes, because the human genome was used as a template (or ”scaffold”) when the chimpanzee draft genome was assembled.
Our new knowledge of the human and chimpanzee genomes contradicts the idea that humans are 98% chimpanzee, and undermines the implications that have been drawn from this figure. It suggests that there is a huge amount exciting research still to be done in human genetics.

You claim that this can be overcome by rapid mutation rate but at the same time you claim that there are vastly more detrimental than useful mutations and there will be genetic meltdown because of the high mutation rates. Something like magic has to occur to compensate between these 2 conflicting events.
I am of course presuming that both you and Bob believe population genetics is a scientific exercise and can legitimately studied by the methods of science. I do.
We agree that boar/pig came from a common ancestor. I allow small changes and long time. You allow small changes but must then postulate phenomenal rates of change (I presume over 2000 years as I assume that the pigs in Jesus time were actually not much different to those you find in the middle east now).

View CommentThat’s not true as genetic mutations rapidly create genetic differences over short periods of time.
No magic is needed to compensate between these ideas. It is a non-contested fact that the vast majority of functionally relevant mutations (i.e., non-neutral mutations) are detrimental to one degree or another. Is is also a non-contested fact that random mutations do rapidly produce novel alleles in a population. Is it possible that some of these allelic mutational changes can be beneficial? Absolutely. It happens all the time at low levels of functional complexity. Does this occasional beneficial change compensate for the overall detrimental mutation rate throughout the entire genome? No. It doesn’t when it comes to slowly reproducing creatures.
I’m glad that you do. Now, why not be consistent in your own arguments regarding population genetics?
I’m not postulating any higher mutation rate than what occurs today. No additional “magic” is needed here. Do the math…

Assuming that the rate of mutation in pigs and boar has remained constant over the last 4000 years since you say that the rate is the same now as then.
Looking at the available data published in the Li paper what are the data.
There are 3832 unique genes in boar
There are 1752 unique gene in the domestic pig
(Sup fig 12)
There are in 30 tibetan boar 8,390,501 SNP
there are in 15 chinese domestic pig 6,011,186 SNP
for a total of 9,492,123 SNP across the asian pigs. Among 103 pigs (30 tibetan boar, 52 domestic pigs and 21 wild boars) 14.64 million SNP
Supplementary table 33,35, sup methods)
In addition there more than 350,000 indels (Sup fig 11)
So from the 2 original animals in a sample of around 100 “pigs” indels have been introduced at nearly 100 per year, SNP have been introduced at 4160 per year and a new gene is introduce every 1-2 years.
Do you think these numbers will decrease if we add warthog into the mix?
You obviously can declare anything you want in terms mutation rates and how many SNP indels and genes were present in the 2 mythical pigs but how many can really be present in the original haplotypes. You have said before that copy number variation was not at all the basis for the genetic richness of the original 2.
Could you give me a reference that shows this mutation rate occurring now? If not I will have to conclude that your model is simply a faith based assertion which I am quite happy to accept. Postulate one miracle you may as well postulate as many as credibility requires.
If you do say it was done miraculously as I suspect Bill would do and Bob might, I would still say it is poor science according to the current well defined model of science but it is logically consistent and unassailable given the assumption of divine creation and divine dispersation and necessary recreation after the flood.

View CommentI see no reason to argue for a significant difference in past mutation rates as compared to today’s rates. Consider that the pig genome is similar in size to the human genome, ~3 billion bases (haploid). The two pigs on the Ark could easily have had a 0.3% difference in genome sequences to start with (with regard to SNPs). Also, in each family line novel SNPs are produced in each generation for each individual at a fairly high rate (up to 100 per individual per generation). And, the generation time for pigs is ~1 year. A comparison between hundreds of pigs from different family lines, even within the same breeding population of average size, would yield a huge number of SNPs in very short order. So, I don’t see why this is an appeal to “magic”?
As far as “unique genes” are concerned, much of this can be explained by a loss of genetic information by one population vs. the other after the split. This is one of the reasons for the “hybrid vitality” already mentioned. Producing such hybrids gives the hybrid offspring access to genes that are missing from each separate gene pool, but were originally available in the ancestral gene pool.
Of course, the production of novel alleles is also a factor. And, in an average population, any beneficial allelic variation would become fixed in relatively short order.
The differences in indels is interesting, but I see no need to invoke magic to explain a few hundred thousand indels in a comparison of hundreds of pigs – especially since muticharacter mutations are quite common as well and would already have existed within the first pair on the Ark to begin with. For example, there are thought to be thousands of conversion mutations per individual in each generation. Combine this with what is generally assumed to be a high rate of inversions/translocations, ~10 duplications/insertions/deletions (changing up to 20 times the number bases that point mutations change per generation), and >100 satellite mutations, and you have yourself a very high overall mutation rate that adds up to many thousands of nucleotide changes per individual per generation.

“The discovery of the Cit + mutants in Lenski’s experiment has been a mote in the eye for those suggesting that major phenotypic innovations cannot be explained by micro-evolutionary (gradual) processes. Indeed, for anti-evolutionists, lack of mechanistic detail has even allowed room for divine intervention. After several attempts to politely address the concerns of one critic, Lenski responded publicly in what has proven to be one of the most competent and direct defences of science versus dogma for some time. It includes the memorable phrase, “In other words, it’s not that we claim to have glimpsed ‘a unicorn in the garden’ — we have a whole population of them living in my lab!”.”
pauluc(Quote)
View CommentDo you know anything about the experiment where Lenski’s produced Cit+ E. coli bacteria?
What Lenski did was to grow E. coli under oxic conditions in citrate-rich media. E. coli bacteria are generally unable to use citrate under oxic conditions as a source of energy. However, they can use it under anoxic conditions. In other words, they already have the gene for citrase in their genome. It is just that it is normally turned off under oxic conditions. How is it turned off? Well, the promoter for the gene that transports citrate into the bacterium is not active under oxic conditions. So, all that needs to happen is to move the citrate transport gene close to a promoter that is actually active under oxic conditions. Once this is done, citrate will enter the bacterium and be used for energy.
And, this is exactly what happened. Nothing structurally new needed to be evolved. After about 31,000 generations, in a large population of bacteria, there was a single genetic mutation in a bacterium that ended up moving the citT gene and placing it under the control of a promoter (rnk) that is active under oxic conditions. The fact that just this single translocation mutation took so long to achieve should clue you in to how difficult it is to achieve even such low-level changes in function via random mutations. The protein product, however, remained the same – i.e., <500aa with no required amino acid changes to achieve a selectable effect. All that was required was to move a pre-existing gene close to a promoter to turn it on during oxic conditions. That's it. The protein itself didn't need to be changed for a useful advantage.
Now, at this point, multiple copies of the gene were rapidly produced in some colonies. However, having just one copy was enough to produce a selectable advantage in the citrate-rich environment. It doesn't matter if there are 1 - 9 copies of the gene - the same function is realized to different levels - i.e., the cit+ function can exist, to a selectable degree, with just one copy of the gene producing the the very same protein. Additional "refinements" are easy once at least a minimum useful level of a particular type of function is realized - not a problem at all.
Again, this "unicorn" of yours is a very low-level example of evolution in action where nothing structurally new was produced to achieve the function in question. The only thing that happened was a mutational move from one location to another within the genome. That's not a statistical problem for Darwinism at all...
Tell me, what is the minimum number of specifically arranged amino acids required to produce a rotary bacterial falgellar motility system? Is it possible to reduce it to less than 1000 specifically arranged residues? – without a complete loss of the motility function?
Again, the concept of functional complexity has been published and is well defined in literature, to include the minimum size requirement. I’ve already given you the references a couple times now.

View CommentIt is supposed to be “The Basis of Biblical Credibility.”
The closer we come to the end of time, it would seem it must come down to those who admit biblical authority vs. those who don’t.
For thousands of years the Jews have “kept the bible Sabbath” on some level. When they give it up for Sunday keeping, they must first admit some authority outside scripture.
While Sunday keeping vs. the bible Sabbath is the outward final test, it is backed by those who accept scripture vs. those who don’t. And those who don’t, must at some point admit they don’t. Otherwise, we will have ongoing and infinite bickering from now ’till dooms day.
God will eventually “force” those who have abandon the bible to say so. At the present time, many “claim” to believe the bible on both sides of any and all issues. This resolves nothing. It must first come to a showdown the makes all who don’t accept the bible finally admit it.
This is how Protestantism vs. Rome eventually came to a final showdown. And Rome eventually admitted the church was not subject to scripture in their evaluation. Once this showdown is completed, then the other issues will naturally resolve themselves because the bible is very clear on all the issues presently being debated. This means, those who opt for obscurity will abandon the bible because they claim it is not clearly revealed what is truth, and what is not, on any given issue.

“Are you saying that you simply accept the claims of experts without a personal understanding of how the Darwinian mechanism actually works at higher levels of functional complexity? – therefore it must work even if you personally do not understand how?”
Sean, I think you’re being a bit hypocritical. You insist that evolutionists must have firm evidence for a mechanism in hand to explain their interpretation of how life has become as we see it today. Yet you cannot explain yourself the mechanisms by which your own interpretation works.
It’s really not okay to say, in essence, “God created the various life forms that are largely similar to what they are today. He saved all the land-dwelling ones in an ark, and only their descendents are with us to this day. We don’t know how God assembled these multifunctional machines in the first place, how fossils became layered in ways that correspond to complexity rather than ecology (e.g., mangroves only high up in the geological column), or how the land-dwelling organisms dispersed in ways that clearly contradict the hypothesis that all departed from a single place (Mt. Ararat). But the mechanisms do not matter; the evidence clearly shows that God did all of this, and therefore it is scientific, even if I personally do not understand how. Evolutionists, on the other hand, cannot explain the mechanism by which evolution assembled multifunctional machines (never mind the other stuff), and therefore their explanation is non-scientific. End of story.”
100 years ago we had no clue that genes could promote cancer. Lacking a mechanism, we could have argued that cancer had nothing to do with our genes. The flaw in any such argument should be obvious to an intelligent mind.
Your argument that evolution cannot work because Paul Cameron or anyone else lacks a precise mechanism to overcome your declared barrier (1000 fairly specified amino acid residues) is based on the fallacy of ignorance.
Jared(Quote)
View CommentThen I suppose SETI science, forensic science, and anthropology are all based on the “fallacy of ignorance” as well? – since these scientists can’t think of any mindless natural mechanism to explain certain types of radio signals, murder victims with certain unnatural features, or pieces of rock with artefactual features?
I’m sorry, but there is no fallacy with the argument for the detection of intelligent design behind various kinds of artefacts – like the origin of a highly symmetrical polished granite cube. It isn’t that these scientists are ignorant of how the phenomenon in question could have been produced by intelligent design. They know how the features they’re considering could have been produced by many different intelligently designed methods. What they don’t know is how the artefact in question could have been produced by any known mindless mechanism of nature. That, my friend, is the very basis of all sciences dealing with the detection of true artefacts of intelligent design.
The very same thing is true of the biomachines within living things that I’m presenting. Clearly, these machines very closely resemble machines that we know were produced by intelligent design. We known and understand how such machines could be produced by various means by intelligent design. What we don’t know is how they could be produced by any mindless natural mechanism this side of a practical eternity of time (i.e., trillions upon trillions of years). This means, of course, that the very best scientific conclusion, the theory with the best predictive power, is that any such biomachine was almost certainly produced by intelligent design.
Now, does the intelligent designer of these biomachines have to be God? No. Not at all. Omnipotence is not required to explain something like a bacterial flagellar motility system. However, even though omnipotence is not required to explain the origin of such machines (to include things like a wrist watch or a granite cube), intelligence of some kind is required.
Does this therefore mean that God did not make something just because God-like power is not required? No. God can make simple stuff just as easily as you and I can make simple stuff. If it just that a God-like creative power is not required to explain everything that God can make. For example, is it possible for God to make a loaf of bread? – the same type of loaf of bread that your mother can make? Sure it is.
It’s funny, don’t you think, that you don’t argue against SETI radio signals or highly symmetrical granite cubes as being anything other than obvious artefacts of intelligent design. Why then the double standard for biological machines that are even farther beyond any known mindless mechanism while being at least closely approximated the creative powers of known intelligent agents?

1] Were there Tibetan Boars, asian domestic pigs and european domestic pigs on the ark or did they all arise from a pig kind?
2] Do you agree with the Authors statement
“Tibetan wild boar has a higher proportion of lineage-specific genes (3,074 of 21,806, or 14.10%) compared with the 1,752 such genes in Duroc pig. Most of the genes specific to Tibetan wild boar (1,903 of 3,074, or 61.91%) have evidence of transcription (Supplementary Table 17), indicating that more new genes have arisen in Tibetan wild boar after the two breeds diverged from each other.”
3] Do you think that this represents “anything beyond very low levels of functional complexity” and that the adaption to high altitude in the Tibetan boars is insignificant and very very low level functional complexity?

As a relevant aside, what is the minimum size requirement for the evolved antifreeze proteins in fish (and other organisms) that live in very cold environments? Do you see any higher level evolution here? – even close to the level of 1000 specifically arranged amino acid residues?

Clearly then, allelic diversity can be rapidly achieved in very short order starting with a very small population. I really don’t think this is seriously debatable…
As far as I can tell, your only real argument was that such a population bottleneck would cause genetic meltdown and extinction. While this is often true today, it would not have been true much closer to Creation because there were far fewer detrimental mutations within the gene pools of all animals during the pre-Flood era. The level of detrimental mutations is the limiting factor here, not small population sizes or the actual mutation rates themselves.

View CommentThe basic math regarding sequence space is relatively simple. For instance, it is very easy to calculate the sizes of sequence space at various levels by simply taking the number of characters in the alphabet and raising that number by the power of the minimum size requirement for the sequence (i.e., the sequence space size needed to hold a 100aa protein is 20^100 = 1e130 sequences). It is also relatively easy to calculate the number of potentially beneficial sequences within sequence space. And, it isn’t that much harder to determine that the distribution of these beneficial sequences is essentially uniform throughout sequence space (although beneficial sequences are clustered into island groups). This information is enough to understand that exponentially greater amounts of time are required for random mutations of any kind to achieve anything beneficial within a higher level of functional complexity.
What do these articles have to do with finding novel beneficial islands within sequence space at various levels of functional complexity? Nothing. Nothing at all. They simply discuss various types of mutations and the differences between genes, but say nothing about the odds of finding a qualitatively novel island of beneficial sequences within a given level of sequence space at a particular level of functional complexity.
For example, here is the abstract of your NCBI paper:
First off, the function in question already existed in the gene pool to begin with, just at “low levels” of activity. Second, a simple increase in the copy number of the gene enhanced the very same type of function – easy. Nothing qualitatively new evolved here. Third, the function in question is an enzymatic function that doesn’t require more than a few hundred specifically arranged residues for minimum selectable activity.
No wonder this process is very rapid! Of course it would be since it is about as low-level as you can get. This is nothing like what it would take to actually find the minimum structural requirement needed to get a qualitatively novel function to work to at least some minimal selectable level of activity. And, this doesn’t even come close to the minimum requirement of 1000 specifically arranged amino acid residues.
Again, you continue to list off these very very low level examples of evolution in action like they mean something when it comes to explaining higher levels of evolution. That is simply a false assumption due to a lack of understanding of the basic math involved with the problem of sequence space…

View CommentI’ve read a bit about this topic over almost 20 years. However, I have not come across any argument, published or unpublished, which explains how random mutations and natural selection can tenably explain anything beyond very very low levels of functional complexity. And, now you seem to be telling me that you don’t personally know of any such published arguments or demonstrations either. After all, I’ve asked you to present such an argument or illustration or demonstration now for a couple of years and you’ve yet to present a single argument or paper along these lines – not one. You’ve told me to do PubMed searches and all, but you’ve failed to actually identify any single relevant paper or argument of any kind that addresses this fundamental question for Darwinism. What you seem to do is what everyone else seems to do – cite low level examples of evolution in action and then extrapolate to higher levels of evolution with the assumption of a linear relationship. When it is shown to you that your linear extrapolation models don’t represent actual reality (an exponential relationship), you have no explanation other than to try to argue that the concept of “levels of functional complexity” hasn’t been defined in literature (which is false) or to argue that some future discovery is sure to support your position (which isn’t scientific).
Are you saying that you simply accept the claims of experts without a personal understanding of how the Darwinian mechanism actually works at higher levels of functional complexity? – therefore it must work even if you personally do not understand how? If so, how is that any kind of challenge to anything I’ve presented? – besides to tell me that experts disagree with me for some reason that you personally don’t understand? Why do they disagree with me? You don’t seem to know. How is that helpful to me or anyone else who sincerely comes to you and asks you, personally, how random mutations and natural selection could possibly do what neo-Darwinians, like you, claim it did? If you don’t know the answer to this very basic question of Darwinism, why not just say so up front? Why even pretend that you know the answer when you really don’t?
If you can’t tell me how the mechanism works, why even think to argue that I should accept something that you yourself admittedly don’t understand? – based only on the word of a bunch of experts? Why even waste your breath trying to convince anyone to accept something that you seem to only understand as a matter of faith in the bold claims of others?
I appreciate that. I know that you are sincere and honest in your position, and that’s the most important thing in my book. My prayers are with you as well.

View CommentWhat does “molecular crowding” (the fact that a cell’s cytoplasm is densely packed with all kinds of molecules) have to do with the concept of discovering new types of beneficial proteins within “sequence space” at various levels of functional complexity? You do realize that sequence space is the space that contains all possible protein sequences of a given length? – and that sequence space has absolutely nothing to do with “molecular crowding”? In other words, the fact of molecular crowding doesn’t make it any easier to find the rare islands of novel beneficial sequences within the vast ocean of sequence space via random mutations.
For example, what is the sequence space size for sequence length of 100aa? It is 20^100 or 1e130 sequences. This is a larger number than all the atoms in the visible universe (~1e80 atoms). Clearly, the concept of “molecular crowding” has nothing to do with the concept of sequence space, which is an entirely different concept. The question is, what is the ratio of potentially beneficial vs. non-beneficial sequences within sequence space? In other words, how many random mutations would it take, on average, to an existing sequence within a genome to get it to mutate into another kind of beneficial sequence? That’s the real question.
Here’s a big clue for you: The density of potentially beneficial sequences within sequence space is very low, even at low levels of functional complexity. It is not “crowded” at all – not even close. There are always more non-beneficial sequences compared to potentially beneficial sequences in sequence space. And, it gets exponentially less and less crowded (with potentially beneficial sequences) with each step up ladder of functional complexity (i.e., with each increase in the minimum size and/or specificity requirements under consideration). This means, of course, that it is exponentially harder and harder to find, within a given span of time, novel islands of beneficial sequences within sequence space at higher and higher levels of functional complexity.
By all means everyone who is at all interested in the implications of these concepts should research the arguments carefully to see who is telling the truth here. Personal research is vital to know if what the “experts” are saying about Darwinism, specially regarding the creative ability of random mutations and natural selection, actually hold water… or even if someone like Dr. Paul Cameron even understands basic concepts like “sequence space” and how random mutations must randomly search through many junk sequences in sequence space before natural selection can do anything…

Sean, I think you’re being a bit hypocritical. You insist that evolutionists must have firm evidence for a mechanism in hand to explain their interpretation of how life has become as we see it today. Yet you cannot explain yourself the mechanisms by which your own interpretation works.
It’s really not okay to say, in essence, “God created the various life forms that are largely similar to what they are today. He saved all the land-dwelling ones in an ark, and only their descendents are with us to this day. We don’t know how God assembled these multifunctional machines in the first place, how fossils became layered in ways that correspond to complexity rather than ecology (e.g., mangroves only high up in the geological column), or how the land-dwelling organisms dispersed in ways that clearly contradict the hypothesis that all departed from a single place (Mt. Ararat). But the mechanisms do not matter; the evidence clearly shows that God did all of this, and therefore it is scientific, even if I personally do not understand how. Evolutionists, on the other hand, cannot explain the mechanism by which evolution assembled multifunctional machines (never mind the other stuff), and therefore their explanation is non-scientific. End of story.”
100 years ago we had no clue that genes could promote cancer. Lacking a mechanism, we could have argued that cancer had nothing to do with our genes. The flaw in any such argument should be obvious to an intelligent mind.
Your argument that evolution cannot work because Paul Cameron or anyone else lacks a precise mechanism to overcome your declared barrier (1000 fairly specified amino acid residues) is based on the fallacy of ignorance.
Jared(Quote)
View CommentThen I suppose SETI science, forensic science, and anthropology are all based on the “fallacy of ignorance” as well? – since these scientists can’t think of any mindless natural mechanism to explain certain types of radio signals, murder victims with certain unnatural features, or pieces of rock with artefactual features?
I’m sorry, but there is no fallacy with the argument for the detection of intelligent design behind various kinds of artefacts – like the origin of a highly symmetrical polished granite cube. It isn’t that these scientists are ignorant of how the phenomenon in question could have been produced by intelligent design. They know how the features they’re considering could have been produced by many different intelligently designed methods. What they don’t know is how the artefact in question could have been produced by any known mindless mechanism of nature. That, my friend, is the very basis of all sciences dealing with the detection of true artefacts of intelligent design.
The very same thing is true of the biomachines within living things that I’m presenting. Clearly, these machines very closely resemble machines that we know were produced by intelligent design. We known and understand how such machines could be produced by various means by intelligent design. What we don’t know is how they could be produced by any mindless natural mechanism this side of a practical eternity of time (i.e., trillions upon trillions of years). This means, of course, that the very best scientific conclusion, the theory with the best predictive power, is that any such biomachine was almost certainly produced by intelligent design.
Now, does the intelligent designer of these biomachines have to be God? No. Not at all. Omnipotence is not required to explain something like a bacterial flagellar motility system. However, even though omnipotence is not required to explain the origin of such machines (to include things like a wrist watch or a granite cube), intelligence of some kind is required.
Does this therefore mean that God did not make something just because God-like power is not required? No. God can make simple stuff just as easily as you and I can make simple stuff. If it just that a God-like creative power is not required to explain everything that God can make. For example, is it possible for God to make a loaf of bread? – the same type of loaf of bread that your mother can make? Sure it is.
It’s funny, don’t you think, that you don’t argue against SETI radio signals or highly symmetrical granite cubes as being anything other than obvious artefacts of intelligent design. Why then the double standard for biological machines that are even farther beyond any known mindless mechanism while being at least closely approximated the creative powers of known intelligent agents?

For thousands of years the Jews have “kept the bible Sabbath” on some level. When they give it up for Sunday keeping, they must first admit some authority outside scripture.
While Sunday keeping vs. the bible Sabbath is the outward final test, it is backed by those who accept scripture vs. those who don’t. And those who don’t, must at some point admit they don’t. Otherwise, we will have ongoing and infinite bickering from now ’till dooms day.
God will eventually “force” those who have abandon the bible to say so. At the present time, many “claim” to believe the bible on both sides of any and all issues. This resolves nothing. It must first come to a showdown the makes all who don’t accept the bible finally admit it.
This is how Protestantism vs. Rome eventually came to a final showdown. And Rome eventually admitted the church was not subject to scripture in their evaluation. Once this showdown is completed, then the other issues will naturally resolve themselves because the bible is very clear on all the issues presently being debated. This means, those who opt for obscurity will abandon the bible because they claim it is not clearly revealed what is truth, and what is not, on any given issue.

Can you given any example of novel systems the require more than 1000 specifically arranged amino acid residues? Please, name just one example and give a relevant quote and reference…
The genome is a collection of systems that function at both low and high levels of functional complexity. And, the aspects of the genome that require a minimum of more than 1000 specifically arranged residues were already there to begin with – within all gene pools.
In this light, consider that making a bunch of 3-letter words is not the same thing as making a single system of function that requires a minimum of 1000 characters to be in place and specifically arranged before it will work at all. That’s an entirely different problem and statistically unlikely, very unlikely, this side of trillions of years of time.
No. Gene duplication is very simple when you’re talking about functional complexity – and is fairly common. Gene duplication, by itself, does nothing more than produce more of the very same thing. And, it doesn’t improve the odds of finding something qualitatively new within sequence space at a given level of functional complexity.
If there were such a “high level” change, you would no doubt share it with us. So, what was this high-level change where something qualitatively new was evolved that required a minimum of more than 1000 specifically arranged residues to work?
When have I not posted your comments? And, when is asking for an actual example of a novel system evolving that requires more than 1000 specifically arranged amino acid residues an unreasonable request? If there is any interposing of a bunch of hocus-pocus here, it’s your argument that some future discoveries are bound to come along to support your Darwinian position – despite any current evidence that might appear to undermine your position.

“The discovery of the Cit + mutants in Lenski’s experiment has been a mote in the eye for those suggesting that major phenotypic innovations cannot be explained by micro-evolutionary (gradual) processes. Indeed, for anti-evolutionists, lack of mechanistic detail has even allowed room for divine intervention. After several attempts to politely address the concerns of one critic, Lenski responded publicly in what has proven to be one of the most competent and direct defences of science versus dogma for some time. It includes the memorable phrase, “In other words, it’s not that we claim to have glimpsed ‘a unicorn in the garden’ — we have a whole population of them living in my lab!”.”
pauluc(Quote)
View CommentDo you know anything about the experiment where Lenski’s produced Cit+ E. coli bacteria?
What Lenski did was to grow E. coli under oxic conditions in citrate-rich media. E. coli bacteria are generally unable to use citrate under oxic conditions as a source of energy. However, they can use it under anoxic conditions. In other words, they already have the gene for citrase in their genome. It is just that it is normally turned off under oxic conditions. How is it turned off? Well, the promoter for the gene that transports citrate into the bacterium is not active under oxic conditions. So, all that needs to happen is to move the citrate transport gene close to a promoter that is actually active under oxic conditions. Once this is done, citrate will enter the bacterium and be used for energy.
And, this is exactly what happened. Nothing structurally new needed to be evolved. After about 31,000 generations, in a large population of bacteria, there was a single genetic mutation in a bacterium that ended up moving the citT gene and placing it under the control of a promoter (rnk) that is active under oxic conditions. The fact that just this single translocation mutation took so long to achieve should clue you in to how difficult it is to achieve even such low-level changes in function via random mutations. The protein product, however, remained the same – i.e., <500aa with no required amino acid changes to achieve a selectable effect. All that was required was to move a pre-existing gene close to a promoter to turn it on during oxic conditions. That's it. The protein itself didn't need to be changed for a useful advantage.
Now, at this point, multiple copies of the gene were rapidly produced in some colonies. However, having just one copy was enough to produce a selectable advantage in the citrate-rich environment. It doesn't matter if there are 1 – 9 copies of the gene – the same function is realized to different levels – i.e., the cit+ function can exist, to a selectable degree, with just one copy of the gene producing the the very same protein. Additional "refinements" are easy once at least a minimum useful level of a particular type of function is realized – not a problem at all.
Again, this "unicorn" of yours is a very low-level example of evolution in action where nothing structurally new was produced to achieve the function in question. The only thing that happened was a mutational move from one location to another within the genome. That's not a statistical problem for Darwinism at all…
Tell me, what is the minimum number of specifically arranged amino acids required to produce a rotary bacterial falgellar motility system? Is it possible to reduce it to less than 1000 specifically arranged residues? – without a complete loss of the motility function?
Again, the concept of functional complexity has been published and is well defined in literature, to include the minimum size requirement. I’ve already given you the references a couple times now.

The absence of a record is of equal importance. Missing time results from rock units that have either eroded away or from periods of time in which no sediment was deposited. Such a gap in the temporal record is called an unconformity, and it’s the geologist’s business (and passion) to decipher what happened during it.

In fact, the Canyon’s rock layers are so full of temporal stratigraphic gaps that far more time is absent than is represented. In Annals of the Former World, John McPhee states, “If a gap of five hundred million years were the right five hundred million years, it could erase the Grand Canyon.”

Mysteriously, the rock layers that once existed between the two formations are missing. Perhaps they never even formed. Regardless of the cause, the space of that paper-thin contact represents an enormous amount of time unaccounted for, far greater than all the others, on the order of a billion years. That’s a quarter of the age of the Earth. Missing!

The Great Unconformity is not just found within the Grand Canyon but occurs in various locations within the Southwest. In fact, it can be found where ancient Laurentia’s Cambrian shelf is exposed and even globally where continental shores received deposition during the Cambrian. Back in New York State where I’m from, we have a Great Unconformity in the Adirondack lowlands in which the Middle Cambrian Potsdam Sandstone overlies a Middle Proterozoic Grenville gneissic-basement on Laurentia’s eastern shore.

I do not think there was any particularly dramatic differences between them such as would be needed to travers your 1000 FSAAR limit. Admittedly there are unique genes in each species but most of these genes do have homologs in other mammalian species so could have evolved by simple loss of some genes in the different species of genes present in the presumed ancestor.

So, I ask you, why did you present this example given that you already knew that it was yet another example of low-level evolution? Why not present just one example of higher level evolution in action or at least explain how such evolution is even likely, statistically, within a reasonable span of time? – like this side of trillions of years?
Now, I know you’re probably going to argue, yet again, that these lower level changes can add up over time to produce higher level changes. However, that’s just not true. Lower level changes remain lower level changes no matter how many of them might be realized. They simply do not add up over time to gain higher levels of functionality – i.e., qualitatively novel systems of function that requires a minimum of more than 1000 specifically arranged amino acid residues to work. The assumption that a bunch of lower level changes will eventually add up to produce more functionally complex systems is a false assumption that misunderstands the nature of sequence space and the statistical limitations involved with the problem.

If you read the paper you will see that in fact there is greater genetic distance between pig and boar than between man and chimp. Loss of genes in the boar/pig is simply analogous to the y chromosome changes in human/chimp. Is this a 1000FSAAR or not?
If you accept that pig and boar arose by a sequence of small genetic changes occurring by gene selection in a gene puddle then you must logically also accept that man and chimp arose by small genetic changes as well. Particularly as you have not identified either in pig/boar or in human/chimp any differences fulfilling your 1000FSAAR barrier beyond simply hinting that Y chromosome changes must be such. I do not believe there is such a barrier. You do but have never even attempted to identify it with any sort of specificity.
pauluc(Quote)
View CommentI’m not talking about a loss of genes. I’m talking about a gain of a qualitatively novel protein-based function that requires a minimum of more than 1000 specifically arranged residues. Do you know of such a novel system or not? If so, please do present it here. Even if humans and chimps did have a common ancestor, how would this help you explain the evolution of higher level systems via RM/NS? – given that such has never been observed and is still statisically impossible this side of trillions of years of time? Such an argument has absolutely no explanatory power and is not scientific (being untestable in a potentially falsifiable manner).
Just for fun though, is there such a difference between humans and chimps? As I’ve explained to you before, there do seem to be such differences on a macro scale – to include structural brain differences that result in higher-level functional differences that require, not just specific 1000aa structures, but entire cellular structures that enable humans to do things that chimps cannot do – things like write books and speak in complex sentences, etc. These functional advantages are not based so much on novel genes, as previously explained, but on how the products of similar genes are used to make different types of structures and systems based on non-coding DNA (which is significantly different between humans and apes). And, as far as I’m aware, there are no such higher-level functional differences between boars and pigs. Consider also that boars and pigs can interbreed to produce viable offspring. This cannot happen between humans and chimps.
Again, you need to focus on functional systems, not genes. Do you have any example of any qualitatively novel system evolving that requires more than 1000 specifically arranged residues? You’ve yet to produce such an example or any mathematical argument that even allows for such an example. You seem to be trying to argue that it must happen because certain species simply must be related. Again, that’s not the same thing as producing an actual example or explaining how such evolution is statistically possible within the vastness of sequence space.
I have given you many specific examples of higher level systems. Yet again, the rotary bacterial flagellar motility system requires a minimum of over 5000 specifically arranged amino acid residues positions to be in place before this type of function will be realized. No system at this level of functional complexity or beyond has ever been shown to evolve nor are there any statistically tenable models on how this might be achieved via random mutations and function-based selection.
As far as this level of differences between pigs/boars, of course I am not aware of such – especially given that pigs and boars and interbreed to produce viable hybrids. As far as humans and chimps are concerned, more and more discoveries are coming to light that highlight fairly significant structural differences that are functionally relevant at a higher level of complexity. And, humans/chimps cannot interbreed. Why not? Well, for one thing the non-coding DNA is very different and is responsible for producing many of the structural/functional differences. And, for another thing, research carried out by scientists at the University of Oxford and the University of Chicago found that hotspot regions that determine the locations for genetic recombination during cellular meiosis in sexual reproduction showed “no overlap between humans and chimpanzees.” This was an “extraordinarily unexpected finding” given the assumed evolutionary relationship between humans and chimps.

I don’t think so.
A useful lie

From 1964 to 2004, it was believed that humans are almost identical to apes at the genetic level. Ten years ago, we thought that the information coded in our DNA is 98.5% the same as that coded in chimpanzee DNA. This led some scientists to claim that humans are simply another species of chimpanzee. They argued that humans did not have a special place in the world, and that chimpanzees should have the same ‘rights’ as humans.
Other scientists took a different view. They said that it is obvious that we are very different from chimpanzees in our appearance and way of life: if we are almost the same as chimpanzees in our DNA sequence, this simply means that DNA sequence is the wrong place to look in trying to understand what makes humans different. By this view, the 98.5% figure does not undermine the special place of humans. Instead it undermines the importance of genetics in thinking about what it means to be a human.
Fortunately (for both the status of human beings and the status of genetics) we now know that the 98.5% figure is very misleading. In 2005 scientists published a draft reading of the complete DNA sequence (genome) of a chimpanzee. When this is compared with the genome of a human, we find major differences.
To compare the two genomes, the first thing we must do is to line up the parts of each genome that are similar. When we do this alignment, we discover that only 2400 million of the human genome’s 3164.7 million ‘letters’ align with the chimpanzee genome – that is, 76% of the human genome. Some scientists have argued that the 24% of the human genome that does not line up with the chimpanzee genome is useless “junk DNA”. However, it now seems that this DNA could contain over 600 protein-coding genes, and also code for functional RNA molecules.
Looking closely at the chimpanzee-like 76% of the human genome, we find that to make an exact alignment, we often have to introduce artificial gaps in either the human or the chimp genome. These gaps give another 3% difference. So now we have a 73% similarity between the two genomes.
In the neatly aligned sequences we now find another form of difference, where a single ‘letter’ is different between the human and chimp genomes. These provide another 1.23% difference between the two genomes. Thus, the percentage difference is now at around 72%.
We also find places where two pieces of human genome align with only one piece of chimp genome, or two pieces of chimp genome align with one piece of human genome. This “copy number variation” causes another 2.7% difference between the two species. Therefore the total similarity of the genomes could be below 70%.
This figure does not take include differences in the organization of the two genomes. At present we cannot fully assess the difference in structure of the two genomes, because the human genome was used as a template (or “scaffold”) when the chimpanzee draft genome was assembled.
Our new knowledge of the human and chimpanzee genomes contradicts the idea that humans are 98% chimpanzee, and undermines the implications that have been drawn from this figure. It suggests that there is a huge amount exciting research still to be done in human genetics.

View CommentAnd this is your scientific argument? Sorry I cannot find anything like that even hinted at in the peer reviewed literature on population genetics.
If I have not been able to make you see that a gene pool in a population of 30 or more is no different to a gene puddle in 2 individuals I have to suspect I cannot.
Of course a population of 2 can increase under ideal conditions to thousands but the effective population size genetically is still 2.
You claim that this can be overcome by rapid mutation rate but at the same time you claim that there are vastly more detrimental than useful mutations and there will be genetic meltdown because of the high mutation rates. Something like magic has to occur to compensate between these 2 conflicting events.
I am of course presuming that both you and Bob believe population genetics is a scientific exercise and can legitimately studied by the methods of science. I do.
We agree that boar/pig came from a common ancestor. I allow small changes and long time. You allow small changes but must then postulate phenomenal rates of change (I presume over 2000 years as I assume that the pigs in Jesus time were actually not much different to those you find in the middle east now).

View CommentThat’s not true as genetic mutations rapidly create genetic differences over short periods of time.
No magic is needed to compensate between these ideas. It is a non-contested fact that the vast majority of functionally relevant mutations (i.e., non-neutral mutations) are detrimental to one degree or another. Is is also a non-contested fact that random mutations do rapidly produce novel alleles in a population. Is it possible that some of these allelic mutational changes can be beneficial? Absolutely. It happens all the time at low levels of functional complexity. Does this occasional beneficial change compensate for the overall detrimental mutation rate throughout the entire genome? No. It doesn’t when it comes to slowly reproducing creatures.
I’m glad that you do. Now, why not be consistent in your own arguments regarding population genetics?
I’m not postulating any higher mutation rate than what occurs today. No additional “magic” is needed here. Do the math…

View Comment@pauluc: Paul, I just want to interject that yes, I believe population genetics is a fully legitimate scientific exercise. However, while I find genetics fascinating, my knowledge of it is very limited, so I’m going to remain quiet as far as blogging is concerned and allow you and Sean to battle it out. I’m reading your comments, but not interjecting mine.
