If textbooks are to be believed, all modern humans come from a population that lived in East Africa around 200.000 years ago. This theory is based on very serious elements: genetic analyzes carried out on humans around the world and the discovery of human bones 195.000 to 165.000 years old, in Ethiopia.
But just recently, a large scientific team - including myself - discovered new fossil bones and stone tools that challenge this theory. http://www.slate.fr/story/146772/quand- ... coup-vieux

The skulls morphologically resemble a discovery located in Florisbad, South Africa, which indicates a trans-African existence of Homo sapiens almost 2,3,4,5 years before Omo 120 and 000. https://fr.wikipedia.org/wiki/Djebel_Irhoud
