Regardless of the extent to which the media promote "politically correct," but scientifically wrong, resolutions from professional societies such as the American Anthropological Association, facts remain facts and require appropriate scientific, not political or ideological, explanation.

But with each passing year and each new study, the evidence for the genetic contribution to these differences becomes more firmly established than ever.
