Forskere har funnet ut at homo sapiens forlot Afrika for bare 60.000 år siden. Det går et skille ved det massive utbruddet fra vulkanen Toba på Sumatra for 74.000 år siden. Noen forskere mente å ha funnet flintredskaper fra tiden før utbruddet. Nå viser nye funn basert på mitokondrier-DNA at mennesket likevel ikke forlot Afrika før flere tusen år senere.

 

Modern humans did not leave Africa prior to the massive eruption of Sumatra´s volcano Mount Toba 74,000 years ago, according to a new study appearing in the journal Proceedings of the National Academy of Sciences.

Rather, Professor Martin Richards of the University of Huddersfield and colleagues have concluded that genetic evidence supports the belief that they departed for Asia approximately 60,000 years ago. Their findings refute a recent theory which had suggested that there was archaeological evidence establishing the presence of people in the southern part of the continent prior to the super-eruption, the university said in a statement.
