S. Shoemaker and S. J. Bus at Palomar. Richard Dawkins (b. 1941), chaired professor at Oxford University, is the author of the seminal work The Selfish Gene (1976) and other best-selling books on science and evolution. His novel concept of the ethology of genes revolutionized the study of evolution and animal behavior. He is the husband of actress Lalla Ward.
