Abstract

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 approximately 65,000 years ago was rapid, most likely taking only a few thousand years.

摘要

近期现代人从非洲向外扩散这一观点已被广泛接受，但穿越欧亚大陆的路线仍存在争议。我们发现，东南亚孤立“遗民”群体中的线粒体DNA变异支持以下观点：仅存在一次从非洲的扩散，最有可能是通过南部沿海路线，途经印度，进而进入东南亚和澳大拉西亚。存在一个早期分支，最终导致近东和欧洲有人定居，但大约65000年前从印度到澳大利亚的主要扩散速度很快，很可能只用了几千年时间。
