DNA studies of aboriginal hair point to 2 waves of migration

"In comparison with DNA from other humans, the DNA in the Aboriginal genome revealed the paths taken by the Aborigines' ancestors when they first migrated out of Africa as the first group to split away from the main group before Europeans and East Asians split from each other, according to the findings.
The rate of mutation in DNA indicates that the Aborigines moved out of Africa possibly 62,000 to 75,000 years ago toward Australia, and that the ancestors of Europeans and East Asians split from each other around 25,000 to 38,000 years ago.
'Aboriginal Australians descend from the first human explorers,' said Willerslev, whose work was published in the journal Science Express on Thursday."
