British biologist Richard Dawkins is blunt in his support for evolutionary theory as opposed to "special creationism." This program, inspired by Dawkins’ book, allows each side to present its best arguments—with some bias toward Darwinian evolution. The evidence is well-organized and current. Creationist ideas are vividly contrasted with contradictory data through observation, computer simulations, robotics, experiments, and close examination of designs in nature. The central argument here is that the diversity we see in such complex adaptations as the eye and insect mimicry can best be explained by cumulative natural selection over long periods of time.
