brindafella writes with a link to an abstract at the journal Science that says "Scientists have obtained a DNA genomic sequence from a 100-year-old, voluntarily donated hair sample from a full-blood Australian Aboriginal man. [Analysis of the hair] 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. ... [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."
