The Selfish Gene is a 1976 book on
evolution by the biologist
Richard Dawkins, in which the author builds upon the principal theory of
George C. Williams's
Adaptation and Natural Selection (1966). Dawkins uses the term "selfish gene" as a way of expressing the
gene-centered view of evolution (as opposed to the views focused on the organism and the
group), popularizing ideas developed during the 1960's by
W. D. Hamilton and others.
From the gene-centered view, it follows that the more two individuals are genetically related, the more sense (at the level of the genes) it makes for them to behave selflessly with each other.
A
lineage is expected to evolve to maximize its
inclusive fitness—the number of copies of its genes passed on globally (rather than by a particular individual). As a result, populations will tend towards an
evolutionary stable strategy. The book also introduces the term
meme for a unit of human
cultural evolution analogous to the gene, suggesting that such "selfish" replication may also model human culture, in a different sense.
Memetics has become the subject of many studies since the publication of the book. In raising awareness of Hamilton's ideas, as well as making its own valuable contributions to the field, the book has also stimulated research on
human inclusive fitness.
