In this commentary, I consider Schmitt's cross-cultural investigation of sociosexuality from a comparative perspective. I argue that such a perspective lends support to an evolutionary explanation of a number of Schmitt's findings, including universal sex differences in sociosexuality and the sensitivity of mating behavior to contextual variables such as sex ratio.
1. As Schmitt demonstrates, however, sociocultural variables also influence the size of the difference.
2. Of course, this does not apply to variables such as the proportion of women in parliament.
3. See Alexander (1979) for discussion of the possibility that invariant mating preferences in humans could give rise to either monogamy or polygyny depending on the distribution of resources in a society.
