Abstract

Polygyny does not necessarily entail sexual selection of men. All factors that affect the operational sex ratio must be considered. Data from contemporary hunter-gatherers indicate higher mortality rates in men than in women, and lost female reproductive time. If sexual selection did occur in ancestral hunter-gatherers, it was probably men selecting women and not women selecting men.
