When I looked to the evidence for these sequences in each region, I couldn' t find the evidence and I started with Europe, with the Neanderthals, where we had the best evidence and the best dated evidence. Looking at this evolution, was there a clear pattern of Neanderthals being if you like half way to being modern humans? Right. Did they make a nice intermediate? And the fact was they didn' t on my data. Certainly as far as I could see, in Australia and that' s region, there was not a good sequence here, from Java man leading to modern Australians. In China, there was not a good sequence leading from Peking man to modern oriental peoples, and there was only one region where there seemed to be a sequence leading to modern humans, and that was in Africa. The pattern seemed to be that there was an evolution in Africa to modern humans, then modern humans spread out from Africa in the last 100, 000 years and developed into the modern humans we know today in each region. And that also means of course that the regional socalled racial features must have evolved after the shared features. So first of all, we get the shared features on humans, then superimposed more recently we' ve got the regional socalled racial differences. So everyone in the world today can trace their ancestry back to people who lived in Africa 150, 000 years ago. |
