ABSTRACT
Contrary to the environmental determinism presumed by most social science commentators, and to the genetic determinism propounded by advocates of hardcore “sociobiology,” the position of this paper is the transactional, epigenetic approach commonly accepted in the life sciences. For the study of humans, this last approach requires a focus upon the reciprocal effects between genotype and both physical and sociocultural environments throughout development. Discussed are: the biology of human sexuality, sex roles and political behavior. The conclusion proposes the development of political models and practices that will take better advantage of the characteristic differences between female and male brains in political thinking and behavior, and that will require a major reversal of the contemporary ratio in sex representation in political roles.
