A recent dispersal of modern humans out of Africa is now widely accepted, but the routes taken across Eurasia are still disputed. We show that mitochondrial DNA variation in isolated “relict” populations in southeast Asia supports the view that there was only a single dispersal from Africa, most likely via a southern coastal route, through India and onward into southeast Asia and Australasia. There was an early offshoot, leading ultimately to the settlement of the Near East and Europe, but the main dispersal from India to Australia 65,000 years ago was rapid, most likely taking only a few thousand years.
An older paper, but I like to keep everything I find for reference As a minor point, the calculted age for M here is 64k, but last time I saw it in print it was more like 74k ago. The last age for L3 I saw was more in the 100k area.
