For a start, let us be clear about what Behe now accepts about evolutionary theory. He has no problem with a 4.5-billion-year-old Earth, nor with evolutionary change over time, nor apparently with its ample documentation through the fossil record -- the geographical distribution of organisms, the existence of vestigial traits testifying to ancient ancestry, and the finding of fossil "missing links" that show common ancestry among major groups of organisms. Behe admits that most evolution is caused by natural selection, and that all species share common ancestors. He even accepts the one fact that most other IDers would rather die than admit: that humans shared a common ancestor with chimpanzees and other apes.
