Richard Dawkins,(shown in the picture) is a British 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. He has written books titled The Selfish Gene, The Extended Phenotype and The Blind Watchmaker.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution. 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.

In the book The Selfish Gene, he introduced a term X which is used in the tech world as a transition of ideas and beliefs.
