Comment on Bringing the Real World to Genesis: Why Evolution is an Idea that Won’t Die—IV [A Review] by George Tasker.

“Seems to me that since we see mutation and critters adaptin’ to their environment now, that would have been the case from the start, unless someone can prove that to the contrary.”
No mutation necessary. The human body when in a cold climate inserts unsaturated fat molecules into the cell walls making them continue to be flexible in the cold climes.
When that human moves to a tropical climate the body gets to work, rips out all the unsaturated fat molecules and puts saturated fat into their place. A process which takes around two years. This explains why it is that it takes around two years for a person to acclimatise to a new climate.
Of course the reverse happens as well. The body obviously has had this adaptability built into it from the very beginning. Don’t need any mutations for this kind of thing to occur. And just in case you’re wondering I found this information in my biochemistry 101 text book.
