Abstract
The phylogenetic analysis of Y chromosomal haplogroup O2a-M95 was crucial to determine the nested structure of South Asian branches within the larger tree, predominantly present in East and Southeast Asia. However, it had previously been unclear how many founders brought the haplogroup O2a-M95 to South Asia. On the basis of the updated Y chromosomal tree for haplogroup O2a-M95, we analysed 1,437 male samples from South Asia for various downstream markers, carefully selected from the extant phylogenetic tree. With this increased resolution, we were able to identify at least three founders downstream to haplogroup O2a-M95 who are likely to have been associated with the dispersal of Austroasiatic languages to South Asia. The fourth founder was exclusively present amongst Tibeto-Burman speakers of Manipur and Bangladesh. In sum, our new results suggest the arrival of Austroasiatic languages in South Asia during last five thousand years.

这里的M1284等价于yfull上的m1283,南亚的M95中m1283最多,符合以前的预期。

这里的B426等价于yfull上的-Y9033,B418等价于yfull上的Z39490,B419等价于同样等价于Z39490。

北蒙达中m1284比例比M95*略高,南蒙达M1284比例比M95*略低,卡西人中M1284比例比M95*略高。孟加拉国和曼尼普尔人中B426占绝对优势。这里应该是两拨不同的人群。
