Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941) is a British ethologist, evolutionary biologist and popular science author. He was formerly Professor for Public Understanding of Science at Oxford and was a fellow of New College, Oxford.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centred view of evolution and introduced the term meme. In 1982, he introduced into evolutionary biology an influential concept, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is well known for his straightforward criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics.

Dawkins is an atheist, secular humanist, skeptic, rationalist and supporter of the Brights movement. He has been referred to in the media as "Darwin's Rottweiler", by analogy with English biologist T. H. Huxley, who was known as "Darwin's Bulldog" for his advocacy of Charles Darwin's evolutionary ideas. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that faith qualifies as a delusion ? as a fixed false belief. As of January 2010, the English language version had sold more than 2 million copies and had been translated into 31 other languages, making it his most popular book to date.
