In a 2006 lecture at Emmanuel College, Cambridge,1 Dr. Graeme Finlay, an immunologist, cancer biologist, and Christian, made some remarkable observations about the genetic similarities of human and nonhuman primate (NHP)2 genomes. He drew the conclusion that these similarities presented incontrovertible genetic evidence for the common ancestry of humans and other primates.3 In doing so, Dr. Finlay employed his expertise in cancer biology to explain the evidence for common descent. I found his presentation compelling.
