The authors of the new study believe that people of the modern species spread from Africa to several migratory flows.
The first people of modern appearance, the ancestors of today's non-African peoples left Africa about 130 thousand years ago. As ScienceDaily reports, this is stated in a study published in the journal Proceedings of the National Academy of Sciences.
A team of scientists, led by Professor Katerina Harvati (Katerina Harvati) from the University of Tubingen (Germany), believes that people of the modern species spread from Africa to several migratory flows. The first people left Africa via the Arabian Peninsula already in the late middle Pleistocene – about 130 thousand years ago. Next they went to Australia and the Western Pacific ocean. Probably from this group occur, the Australian aborigines, the Papuans and Melanesia.
Other Asian population – the descendants of migrants who left Africa about 50 thousand years ago. This group of people went to Northern Eurasia.
Most scientists agree that all modern humans are descended from a common population that existed in the period from 100 to 200 millennia of millennia ago. The reduction in genetic and phenotypic diversity was observed with increasing distance from Africa, was often considered a symptom of one wave of migration. This wave has dated between 50 and 75 thousand years ago.
New research has helped to refute this point of view. To do this, scientists compared the skulls of modern humans from different parts of the world, and used genetic data and information about distances of proposed route of settlement. "Both strands of evidence – the comparison of skulls, and genetic data indicate multiple models of settlement," says Katherine Harvati.
