In the light of such evidence, it is not surprising that many Christian philosophers have accepted the hypothesis of common descent, and have adopted some form of theistic evolution, in which the creator intervened at some point to transform some earlier primates into members of a new species, Homo sapiens. But while this version of special creation is an improvement, given the very close relations between human and chimpanzee DNA, and the fact that known mechanisms of chromosome rearrangement render the transition from some non-human species to Homo sapiens not at all improbable, the postulation of divine intervention at that particular point does not seem plausible.
