Comment on "Reconstructing the Origin of Andaman Islanders"

Malliya gounder Palanichamy,1,2 Suraksha Agrawal,3 Yong-Gang Yao,2 Qing-Peng Kong,2 Chang Sun,2 Faisal Khan,3 Tapas Kumar Chaudhuri,4 Ya-Ping Zhang1,2*

On the basis of mitochondrial DNA sequence analyses, Thangaraj et al. (Brevia, 13 May 2005, p. 996) proposed that Andaman islanders descended from the first humans to migrate out of Africa. We identified mitochondrial DNA from two northeast Indian Rajbanshi individuals that shares three specific mutations with the M31a lineage observed in the Great Andamanese, which suggests that the predecessor of haplogroup M31 originated on the Indian subcontinent.
