The University of California, Irvine's evolutionary biologist and geneticist Francisco Ayala has a new book out called Darwin's Gift to Science and Religion -- and Jonathan Eisen is relieved that someone besides Francis Collins is discussing religion and science. In the New York Times, Ayala, a former Dominican priest from Spain, says he is surprised by the number of Americans who think that believing in evolution rules out believing in God. Ayala also dismisses teaching intelligent design or creationism alongside biology. "We don't teach alchemy along with chemistry," he says.
