Genetics reveal 50,000 years of independent history of aboriginal Australian people

The first complete sequences of the Y chromosomes of Aboriginal Australian men have revealed a deep indigenous genetic history tracing all the way back to the initial settlement of the continent 50 thousand years ago, according to a study published in the journal Current Biology today (25th February 2016).

The study by researchers from the Wellcome Trust Sanger Institute and collaborators at La Trobe University in Melbourne and several other Australian institutes, challenges a previous theory that suggested an influx of people from India into Australia around 4-5 thousand years ago. This new DNA sequencing study focused on the Y chromosome, which is transmitted only from father to son, and found no support for such a prehistoric migration. The results instead show a long and independent genetic history in Australia.

As there has been little or no mixing with other human groups, these Aboriginal Australians must be very close to the early exodus from Africa. It's hard to imagine a group of modern humans traveling such a distance where only earlier human species were and finally settling at the furthest place they could reach.

No one else was able to travel there until quite recently.

There was a special I saw that these aboriginals from Australia even made it to South America.

Study suggests Aboriginal ancestors may have colonised South America

It challenges theories of how Native Americans first arrived in the Americas
