Neanderthals left humans genetic burden, scientists say
6 June 2016, Sci-News
The genome of Neanderthals contained harmful gene variants that made them around 40 percent less reproductively fit than modern humans. And non-Africans inherited some of this genetic burden when they interbred with our extinct cousins, say genetic researchers.

How the origins of the Khoisan disprove notions of ‘race’
04 February 2016, Mail&Guardian
The ancient origins, anatomical, linguistic and genetic distinctiveness of southern African San and Khoikhoi people are matters of confusion and debate. They are variously described as the world’s first or oldest people; Africa’s first or oldest people, or the first people of South Africa. They are in fact two evolutionarily related but culturally distinct groups of populations that have occupied southern Africa for up to 140 000 years. Their first-people status is due to the fact that they commonly retain genetic elements of the most ancient Homo sapiens. This conclusion is based on evidence from specific types of DNA. This evidence also demonstrates that other sub-Saharan human populations retain genetic bits and pieces of DNA from non-KhoiSan primordial humans. These pre-date their out-of-Africa colonisation of the balance of the world.
