Abstract

Einon's data support our original claims, although not a claim she seems to assume – of reciprocal attraction between elderly men and 20-year-old women. Implicit in her commentary is an assumption that genetic predispositions are omniscient fitness maximizers. Instead, evolutionary models assume selection-fashioned psychological mechanisms that, in the context of other mechanisms and pressures in past environments, had a positive effect on fitness relative to competing alternatives. The Over & Phillips data fit with our own data on homosexuals, and with the assumption of independent modular mechanisms, rather than any existing sociocultural models. Einon also incorrectly assumes that evolutionary models have overemphasized male choice to the exclusion of female choice.
