Genetic study challenges Americas settlement theories by linking Amazonians and Australasians
DID an ancient tribe of Australian Aborigines colonise the Amazon? Unexpected new DNA results may have uncovered a long-forgotten wave of migration some 15,000 years ago.
The established thinking is that the first Americans were descended from a single wave of Eurasian tribes that had crossed an ancient “land-ice bridge” between Alaska and Russia into a New World — when the climate was much cooler and sea levels lower.
It’s an idea seemingly supported by a report published this week in the journal Science: It presents evidence Native Americans entered the Americas as a single wave.
But another genetic study by Harvard University published in the journal Nature yesterday is a direct challenge to this idea.
