The Selfish Gene

The Selfish Gene is a 1976 book on evolution by Richard Dawkins, in which the author builds upon the principal theory of George C. Williams's Adaptation and Natural Selection . Dawkins uses the term "selfish gene" as a way of expressing the gene-centred view of evolution , popularising ideas developed during the 1960s by W. D. Hamilton and others. From the gene-centred view, it follows that the more two individuals are genetically related, the more sense it makes for them to behave selflessly with each other.

Context: Genes do indirectly control the manufacture of bodies, and the influence is strictly one way: acquired characteristics are not inherited. No matter how much knowledge and wisdom you acquire during your life, not one jot will be passed on to your children by genetic means. Each new generation starts from scratch.
