Clinton Richard Dawkins  (born 26 March 1941) is an English ethologist, evolutionary biologist, and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008. Dawkins first came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centred view of evolution and introduced the term, meme. With his book The Extended Phenotype (1982), he introduced into evolutionary biology the influential concept that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment.

Dawkins is a prominent critic of creationism, a religious belief that humanity, life, and the universe were created by a deity without recourse to evolution. He has described the Young Earth creationist view that the Earth is only a few thousand years old as "a preposterous, mind-shrinking falsehood"; and his 1986 book, The Blind Watchmaker, contains a sustained critique of the argument from design, an important creationist argument. In the book, Dawkins argues against the watchmaker analogy made famous by the eighteenth-century English theologian William Paley via his book Natural Theology, in which Paley argues that just as a watch is too complicated and too functional to have sprung into existence merely by accident, so too must all living things--with their far greater complexity--be purposefully designed. Dawkins shares the view generally held by scientists that natural selection is sufficient to explain the apparent functionality and non-random complexity of the biological world, and can be said to play the role of watchmaker in nature, albeit as an automatic, unguided by any designer, nonintelligent, blind watchmaker.  In 1986, Dawkins and biologist John Maynard Smith participated in an Oxford Union debate against A. E. Wilder-Smith (a Young Earth creationist) and Edgar Andrews (president of the Biblical Creation Society). In general, however, Dawkins has followed the advice of his late colleague Stephen Jay Gould and refused to participate in formal debates with creationists because "what they seek is the oxygen of respectability", and doing so would "give them this oxygen by the mere act of engaging with them at all". He suggests that creationists "don't mind being beaten in an argument. What matters is that we give them recognition by bothering to argue with them in public." In a December 2004 interview with American journalist Bill Moyers, Dawkins said that "among the things that science does know, evolution is about as certain as anything we know." When Moyers questioned him on the use of the word theory, Dawkins stated that "evolution has been observed. It's just that it hasn't been observed while it's happening." He added that "it is rather like a detective coming on a murder after the scene... the detective hasn't actually seen the murder take place, of course. But what you do see is a massive clue... Huge quantities of circumstantial evidence. It might as well be spelled out in words of English."  Dawkins has opposed the inclusion of intelligent design in science education, describing it as "not a scientific argument at all, but a religious one". He has been referred to in the media as "Darwin's Rottweiler", a reference to English biologist T. H. Huxley, who was known as "Darwin's Bulldog" for his advocacy of Charles Darwin's evolutionary ideas. (The contrasting sobriquet of "God's Rottweiler" was given to Pope Benedict XVI while he was a cardinal working for the Congregation for the Doctrine of the Faith.) He has been a strong critic of the British organisation Truth in Science, which promotes the teaching of creationism in state schools, and whose work Dawkins has described as an "educational scandal". He plans to subsidise schools through the Richard Dawkins Foundation for Reason and Science with the delivery of books, DVDs, and pamphlets that counteract their work.
