brindafella writes "Scientists have obtained a DNA genomic sequence from a 100 year old, voluntarily donated hair sample from a full-blood Australian Aboriginal man. This shows "Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago. This dispersal is separate from the one that gave rise to modern Asians 25,000 to 38,000 years ago. [They] also [found] evidence of gene flow between populations of the two dispersal waves prior to the divergence of Native Americans from modern Asian ancestors. [Their] findings support the hypothesis that present-day Aboriginal Australians descend from the earliest humans to occupy Australia, likely representing one of the oldest continuous populations outside Africa." A news story gives more detail." Link to Original Source
