Gene Flow

The movement of genes from different populations of species.

Sometimes geological events, or geographical barriers for example, can interrupt the free movements of genes in a species population. This can lead to speciation over long periods of time due to subtle changes in the gene pool of each of the splinter groups on each side of the geographical barrier.

Brain size=IQ level theory (Blacks vs Whites & Asians)

... If we ever get evidence that—environmental influences equal—African genetics are generally more favorable to the development of intelligence, I would pose the hypothesis that it's due to (a) gene flow throughout a larger population (the population of Africa) allowing for more ...
