The human species may have originated from East Africa, but that does not mean that non-sub-Saharan-Africans are descended from sub-Saharan-Africans (bantu). Bantu split off from the rest of the human population around 40,000 years ago and have been evolving separately since then. This separate evolution becomes obvious when scientists go genetic analyses of human populations. Whatever progenitor population of humans that everyone came from (including the bantu) no longer exists. So the article from "Scientific" American is just another leftist lie to mislead people to believing that Bantu are everyone's ancestors.
