mitochondrial DNA macrohaplogroup M colonized India from southeastern Asia

Patricia Marrero et al.

Objetives We suggest that the phylogeny and phylogeography of mtDNA macrohaplogroup M in Eurasia and Australasia is better explained supposing an out of Africa of modern humans following a northern route across the Levant than the most prevalent southern coastal route across Arabia and India proposed by others.
Methods A total 206 Saudi samples belonging to macrohaplogroup M have been analyzed. In addition, 4107 published complete or nearly complete Eurasian and Australasian mtDNA genomes ascribed to the same macrohaplogroup have been included in a global phylogeographic analysis.
Results Macrohaplogroup M has only historical implantation in West Eurasia including the Arabian Peninsula. Founder ages of M lineages in India are significantly younger than those in East Asia, Southeast Asia and Near Oceania. These results point to a colonization of the Indian subcontinent by modern humans carrying M lineages from the east instead the west side.
Conclusions The existence of a northern route previously advanced by the phylogeography of mtDNA macrohaplogroup N is confirmed here by that of macrohaplogroup M. Taking this genetic evidence and those reported by other disciplines we have constructed a new and more conciliatory model to explain the history of modern humans out of Africa.

我还是那句话,主要看树形。你不能因为印度分支上的突变少就说它年轻。

论文的观点很可能是对的。但如果只是已发表数据资料的一个汇总,那价值就不大。

这是附录中的图,文章所提hp的树,深红色是印度的。突变少就年轻?拿衣物!

看到印度的M来自东方就笑了 看来坛子里懂的人蛮多的

1# sahaliyan 根据路线图,C,Z,m8起源于G;D是东亚绝大部分M系的源头。太惊讶!跟之前看到的世界NMR系线粒体进化图上的M系完全不一样,不知道哪个是错的。
