David B has right here made a very good point, which I believe is
critical. Michael Denton has made a similar point. In his recent
writings he has said that when he wrote his book Evolution: Theory in
Crisis (1986) he made two errors. The first error was one of choice of
title -- he should have titled the book Darwinism: Theory in Crisis.
The second error was one made in ignorance of scientific advances at
the genomic level that have been made in the last two decades. He now
sees how large differences in phenotype can plausibly arise from small
changes at the molecular level. Denton was once a Fellow of the
Discovery Institute but now he is a critic of the Intelligent Design
movement as formulated and promulgated by Phillip Johnson, Michael Behe
and William Dembski.
