This article discusses the impact of the development of biosocial approaches, a recombination between specialties in the field of social sciences and evolutionary biology, with the sociological field. Contrary to the idea that biosocial approaches such as sociobiology has no place within sociology, we thus defend : (1) That although sociology in its most traditional and fundamental specialties is the most adamant social science to enlist in the second Darwinian revolution, in peripheral specialties the impact of sociobiology has been considerable; (2) That the institutionalization of an evolutionary sociology represents the triumph of sociobiology in the sociological field.
