Bones of Stone Age boy challenge single-origin theory of modern humans
The 2,000-year-old bones of a boy found on a beach in South Africa have provided more grounds to challenge the prevailing theory that modern humans had a single origin in north-eastern Africa.
That fraying theory, based on fossils found at Omo Kibish and elsewhere in Ethiopia, dates the emergence of modern humans to about 180,000 years ago. However, by using DNA analysis as a ‘molecular clock’ to calculate the length of time since the boy’s ancestors diverged genetically from other groups of modern humans, scientists in South Africa and Sweden estimate that modern humans must have existed between 260,000 and 350,000 years ago.
