He notes that studies on the anatomy of living primates are used to support evolution. In begging the question, one assumes to be true the very thing you are trying to prove. At first glance, a bicycle seems enough like a motorcycle to be its precursor. On deeper investigation, while a bicycle resembles a motorcycle, the parts of a bicycle cannot be molded into a motorcycle by a process resembling evolution. As explained by Behe, a bicycle has nothing that can be modified to become a gasoline tank, for example.
Darwinian evolution requires physical pre-cursors.
As an example, Denton discusses mammalian hair, and points out that there is no evolutionary pre-cursor. Or consider the metamorphosis of the butterfly. There is no conceivable evolutionary precursor to this astounding event. Biology is fraught with such problems for evolution. The Problem of Molecular Isolation Denton also devotes a detailed chapter in his book about the biochemical matrix of organisms.
