I read with interest a short story in the Sydney Morning Herald suggesting that DNA testing had established possible links between early populations in what is now India and the Australian Aborigines, although I thought that the headline (First Australians were Indian) was a bit silly.
Those who are interested can find the original research piece here. It does seem to add support to the idea that at least some of Australia's early settlers came to Australia via India though the then extended South East Asian landmass and into what is now Australia via the Southern sea route.
I found the story very interesting if not especially surprising. One of the things about Australia's relative isolation from the west of the world and the continent's long human occupation is that the continent provides a window into the human past in a way not possible in other, more fought over, areas.
