现代人类最近从非洲向外扩散的说法现在被广泛接受，但穿越欧亚大陆的路线仍然存在争议。我们发现，在东南亚孤立的“孑遗”人群的线粒体DNA变异支持这样的观点，即只有一个单一的分散从非洲，最有可能通过南部沿海路线，通过印度和前进到东南亚和澳大拉西亚。早期有一个分支，最终导致近东和欧洲的定居，但主要的传播从印度到澳大利亚类似于65，000年前是快速的，很可能只花了几千年。
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 similar to 65,000 years ago was rapid, most likely taking only a few thousand years.
