Abstract
Any evolutionary explanation of
institutions must necessarily presuppose regularities which are themselves not
subject to the evolutionary processes studied. The essay highlights the
necessity of patterning from an evolutionary perspective and emphasizes the
strong parallelism of patterning in biological and social evolution. It is
argued that processes of social and institutional evolution build on the
psychological patterning of human motivation and action. As a result, we cannot
start from the individual mind as a tabula
rasa, but must posit psychological regularities from the beginning.
Keywords: social evolution, patterned variation, directed variation, adaptive
landscapes, constraints, channeling, hitchhiking, radiation, founder effect,
irreversibility, functional shift, punctuation, evolutionary detour, organic
growth, development
