Skulls confirm we’re all African
An analysis of thousands of skulls shows modern
humans originated from a single point in Africa.
An analysis of thousands of skulls shows modern humans originated from a single point in Africa and finally lays to rest the idea of multiple origins, British scientists said on Wednesday.
Most researchers agree that mankind spread out of Africa starting about 50,000 years ago, quickly establishing Stone Age cultures throughout Europe, Asia and Australia.
Genetic evidence has always strongly supported the single origin theory, and now results from a study of more than 6,000 skulls held around the world in academic collections supports this case.
Andrea Manica and colleagues wrote in the journal Nature that variations in skull size and shape decreased the further a skull was away from Africa, just like variations in DNA.
The study also concludes that virtually no successive interbreeding with Neanderthals occurred. Regardless of what you may think of American politicians.
