Higher genomic diversity is just another way of saying there's more ethnic groups in Africa, right? So it's not particularly a racial thing.

- afiori 7y agoif I remember correctly from a genetic perspective the group of "not African ethnicities" is more uniform than the group of "African ethnicities"
- xiphias2 7y agoIt's a historical thing: humans were evolving for much longer time in Africa than in other continents.
- username90 7y agoAll humans have evolved for the same amount of time. It is just that a smaller part of the population decided to emigrate than to stay a long time ago.
- bonzini 7y agoMigration causes a genetic bottleneck that (sort of) resets the counter.
- afiori 7y agoyes, but for much longer in Africa than outside of Africa. If you assume that "diversity" increases mostly steadily over time* then there is much more diversity in Africa than in the rest of the world. * diversity is quite different from evolution
