DNA from the hair demonstrates that indigenous Aboriginal Australians were the first to separate from other modern humans, around 70,000 years ago.
This challenges current theories of a single phase of dispersal from Africa.
An international team of researchers published their findings in the journal Science.
While the Aboriginal populations were trailblazing across Asia and into Australia, the remaining humans stayed around North Africa and the Middle East until 24,000 years ago.
