Dawkins contends that religion and evolutionary theory are incompatible. Alister McGrath, a molecular biophysicist turned Anglican pastor, disagrees. “What Dawkins shows, strictly speaking, is simply that the theory of evolution leads to agnosticism—a principled uncertainty about whether there is a God or not,” says McGrath. “And in driving it to atheism—that there is necessarily no God—he goes way beyond the limits of the evidence.”
