The evidence for common ancestry is so overwhelming that even the biologist Michael Behe (whose books advocate “intelligent design,” and who is a senior member at the Discovery Institute) concurs. Behe wrote in his second book:
“Evolution from a common ancestor, via DNA changes, is very well supported” (p. 12).
“[O]ne leg of Darwinʼs theory—common descent—is correct” (p. 65).
