The Selfish Gene

Richard Dawkins argues that the fundamental unit of selection in evolution is neither the species nor the individual, but the gene. This gene-centered view of selection posits that organisms are mere survival machines built by self-replicating molecules to ensure their own propagation into the next generation. Dawkins uses this framework to explain biological altruism, showing how behaviors that appear self-sacrificing, such as social insect colonies or parental care, are actually strategies that maximize the survival of shared genetic sequences. He also introduces the meme as a cultural analogue to the gene.

This book is intended for students of biology and laypeople interested in evolutionary theory. Readers gain a logical toolkit for analyzing animal behavior through the lenses of game theory and the prisoner’s dilemma. Instead of viewing nature as a struggle for the survival of a group, the reader learns to interpret every biological interaction as a calculated outcome of genetic competition. The text provides a clear mental model for understanding why kin selection and reciprocal cooperation occur in a world governed by competitive replication.
