The quote from JeffScott in the previous post reminded me of certain radical feminist theories about social relations in the supposed days of prehistoric matriarchy, which in turn prompted some thoughts about the study I linked to earlier (and the common assumption that it seems to confirm) about men's inherent promiscuity. One theory about matriarchal sexual relations holds that promiscuity was once deliberately practiced by women in order to foil attempts to determine a child's paternity. The idea of sexual fidelity was then invented by men as part of their consolidation of power once they got control.
