Humanity, like all species, evolves through changes in the frequency of genetic variants over time. Where there is less diversity — less possible genetic variants to have their frequency varied — there is less evolution. The aboriginies of Austarlia, for example, are dark skinned in spite of living at a mid-lattitute for thousands of years. This does not mean that there is some health advantage to being dark skinned at a mid latitute — quite the opposite! Rather, there simple was not enough diversity in the the population of aborginies to enable evolution over that time frame.

Populations with greater diversity are able to evolve faster for their conditions. Thus, it is slightly horrifying than the region with the worst living conditions (where selection pressures are least like those of the developed world)

The Long War for Africa and Islam

and the region with the highest birthrates:

is also the region with the most genetic diversity: Africa.

Extrapolating from other species, behavioral change from natural selection might occur in human beings in as little as 200 years. We are approximately fifty years into the Declonization of Africa, and the genocidal nightmare that unleasehd.

Forgetting about the actual human cost of this gappish hell, there is still time to be patient. There is time to let a plan work to shrink the gap.

But it must begin soon.
