Richard Dawkins: The legacy of the selfish gene theory

Fifty years after the publication of “The Selfish Gene” in 1976, the theories of British evolutionary biologist Richard Dawkins continue to influence scientific research. Dawkins shifted the focus of evolutionary biology from species-level competition to the perspective of individual genes, proposing that organisms act as survival machines for genetic information that persists across generations.

A central theme of his work is the paradox of how genetic competition can drive altruistic behavior. For example, an animal might risk its life to warn others of a predator, an act that appears selfless but serves to protect close relatives who share identical gene variants, thereby ensuring the survival of those genes.

While the book's title often led to public misconceptions regarding inherent selfishness in nature, Dawkins intended to illustrate how biological competition can result in cooperation and sacrifice. His work emerged during a period of intense academic debate regarding the intersection of biology and social behavior, following other major works like Edward O. Wilson’s “Sociobiology”.
