The controversial evolutionary biologist and fervent atheist Richard Dawkins rose to fame in 1976 with his publication of The Selfish Gene. In it, he builds on George C. Williams’s theory of Natural Selection as a way of expressing a gene-centred view of evolution. The Extended Phenotype introduces a new biological concept, and is considered to be a direct sequel to this work. Dawkins argues that phenotype (the set of observable characteristics of an organism) should not be limited simply to biological processes such as tissue growth, but extended out to include the effects that a gene has upon its environment, both inside and outside the body of an organism. Although the book is intended for professional biologists, it was Dawkins’s hope that it could also be read by the layperson not well versed in evolutionary biology, and as such he includes a glossary of technical terms to the rear of the text. Despite this fact, it was still considered to be a technical work, and therefore published in much smaller numbers than The Selfish Gene. First editions in this condition, therefore, which have not been read or used in a practical setting, are becoming increasingly scarce. 
 
The Extended Phenotype is now considered to be one of Dawkins’s principal contributions to the field of evolutionary biology.
