One of those interesting cases where a scientific development seems on its face to rebut scientific racism, and instead becomes incorporated into it. Because scientific racism is a degenerate research programme, its adherents were able to jettison any hypotheses that seemed like part of the core and replace them with new ones. As long as you realize that the actual core is the racism, not the science, then the dynamic makes perfect sense.<p>They could now argue that Out of Africa was in fact proof of the superiority of whites, who had clearly evolved since leaving Southern Africa. Of course, any evidence that this is not the case can be ignored, keeping the true core of the research programme intact.
