Evolutionists have a wide range of explanatory mechanisms from which to draw when trying to figure out how the species evolved. But sometimes these supposed mechanisms look more like a cover-up than an explanation. For instance, the differences between the human and chimp DNA instructions are not sprinkled, more or less at random, throughout our genome. Rather, these differences are found in clusters. Even more interesting, at these locations the chimp's genome is quite similar to other primates--it is the human that differs from the rest, not the chimp. Evolutionists refer to these clusters as human accelerated regions (HARs) because they believe the human genome evolved from a human-chimp common ancestor. These HARs cause several problems for evolution. For instance, we must believe that evolution magically caused rapid changes to occur right where needed to improve function and eventually create a human. As one evolutionist wrote:
The way to evolve a human from a chimp-human ancestor is not to speed the ticking of the molecular clock as a whole. Rather the secret is to have rapid change occur in sites where those changes make an important difference in an organism’s functioning. HAR1 is certainly such a place. So, too, is the FOXP2 gene, which contains another of the fast-changing sequences I identified and is known to be involved in speech.
This is truly a whopper of a just-so story and you can read more here and here.
Now, evolutionists are again appealing to this accelerated evolution "mechanism" to explain the origin of a toxic protein found in the saliva of a North American shrew. The protein chops up other proteins using a novel mechanism, and evolutionists are saying that it "evolved adaptively via acquisition of small insertions and subsequent accelerated sequence evolution."
There you have it--evolution happens. But that's not all. Evolution implemented the same clever design in a Mexican lizard. Amazing.
This is yet another example of a striking design repeat in biology, but this time it is via accelerated evolution. Evolutionists have not calculated the probability of blind mutations doing this not once but twice, probably because it doesn't matter. After all, evolution is a fact.
