Much that Darwin said about sexual selection in1871 is culturally and socially biased. His theory attempts to explain why males and females differ, often in ways that are contrary to expectations given natural selection. Roughgarden et al. (p. 965) offers an alternative model that presents social selection theory based on cooperative game theory. Thus, cooperation among individuals in sexual relations, as in other social relations, generates advantages such that groups of individuals that succeed in cooperation may have greater fitness vis-à-vis groups that fail to cooperate. Such differences could generate selection pressure toward individuals and groups that cooperate.
