Robert Crowther has posted a criticism of Francis Collins on Evolution News & Views (sic): Francis Collins, Evolution and "Darwin of the Gaps".
Much of Collins’s case for Darwinian evolution is based on so-called “junk DNA.” This is the part of the genome that does not appear to code for the production of proteins. In mammals, the vast majority of DNA has been dismissed as “junk.”I don't want to defend Francis Collins. I want to emphasize something else; namely that the concept of junk DNA is about as far removed from "Darwinism" as you can possibly be and still be an evolutionary biologist. If it has any meaning at all, "Darwinism" has to be a synonym for the belief in natural selection as the most potent mechanism of evolution. Junk DNA is completely non-Darwinian and there's no way you could describe it as compatible with "Darwinian theory."
Junk DNA, according to Darwinists like Collins, gives evidence of common descent—the idea that all life, including human life, branches off from a common evolutionary tree. As life evolved, according to this view, garbled, useless genetic information accumulated and has remained fixed—like dirt swept under a carpet—even as mammals, for example, diversified from a common ancestor.
But the argument from junk DNA—also called “ancient repetitive elements” (AREs)— depends on the premise that no function will ever be discovered for AREs. Collins’s faith in Darwinian theory would be severely hamstrung if the premise were shown to be wrong. It is a faith based on gaps in scientific knowledge. Hence, “Darwin of the gaps.”
Why do creationists have so much trouble understanding this? It's not that hard.
