Genes, culture, and scientific racism.

Quantitative studies of cultural evolution and gene-culture coevolution (henceforth “CE” and “GCC”) emerged in the 1970s, in the aftermath of the “race and intelligence quotient (IQ)” and “human sociobiology” debates, as a counter to extreme hereditarian positions. These studies incorporated cultural transmission and its interaction with genetics in contributing to patterns of human variation. Neither CE nor GCC results were consistent with racist claims of ubiquitous genetic differences between socially defined races. We summarize how genetic data refute the notion of racial substructure for human populations and address naive interpretations of race across the biological sciences, including those related to ancestry, health, and intelligence, that help to perpetuate racist ideas. A GCC perspective can refute reductionist and determinist claims while providing a more inclusive multidisciplinary framework in which to interpret human variation. [ABSTRACT FROM AUTHOR]
