Francisco Ayala is an evolutionary biologist at the University of California, Irvine. Ayala is also an ordained Dominican priest. He believes that evolution and creationism can coexist. Ayala states that there is a better approach to getting creationists on board with evolution than those employed by the likes of Richard Dawkins, who tends towards ridiculing the faithful. He feels that simply "engaging religious people in dialogue" will assist in allowing the coexistence of religion and science.
