About the seminar
Is cultural selection real, or merely a ghostly relict from the genetics of the thirties?

A central tenet of human behavioral ecology holds that facultative behaviors, such as those associated with dominance, produce fitness effects that are subject to cultural selection. “In more than one hundred well studied societies", according to a recent review, “high-ranking men have the right to more wives." But evidence for such selection is inconclusive, based on short-term statistical associations between behaviour and fertility. And the underlying model of selection, based on Fisher´s “fundamental theorem of natural selection" (circa 1930), is no longer taken seriously in population genetics.

The neutral theory, which infers selection at the population level, provides a way to measure the nature and extent of both cultural and genetic selection. In 41 Indonesian villages, we find little evidence for either form of selection associated with male dominance. This first test of the neutral theory in anthropology suggests that, as in genetics and ecology, the appropriate null model is not pan-selection, but neutrality.
