Hamilton, William Donald

British biologist; Hamilton developed the concept of inclusive fitness and kin selection and was able to demonstrate, at least mathematically, how it could be possible to model altruistic behaviors in terms of neo-Darwinist principles. These two seminal papers led to the elaboration of sociobiology: The evolution of altruistic behavior (1963), and The genetical evolution of social behavior (1964). Hamilton’s collected papers appear in two volumes called The Narrow Roads of Geneland. Volume 1: Evolution of Social Behavior (1996), and Volume 2: Evolution of Sex (2002). Winner of the Royal Society’s Darwin Medal (1988).

See altruism and second Darwinian revolution.
