India still has the `out of africa' genetic footprint.
The M2 mitochondrial DNA haplogroup split from the main M haplogroup in India about 50,000 years ago.
About 10% of tribals have this haplogroup.
A study of 132 people from 25 groups, plus 560,000 snps(405 snps from 55 groups).
Nyshi and ao naga respectively tribals in Arunachel pradesh and Nagaland,speakers of a Tibeto-burman language genetically cluster with the chinese..
Those who speak Indo-european or were of higher castes eg brahmin,I presume, tended to cluster with western eurasians.
