Furthermore, in response to serious misses and distortions by other authors; I must point out that genetics have shown that there’s more genetic diversity within any population of humans you try to identify than there is between any various population. Making it impossible to imply any pure population anywhere on the planet that does not indeed have “ancestors who came from somewhere else”. Humans have historically been well adapted to be able to migrate and the origins of our singular human race is in the African continent. Nothing I’ve said prefacing the other authors’s discussion on race and ethnicity is in dispute by the modern field of biological anthroplogy, nor could it be disputed scientifically with any veracity.
