austro-asiatic populations

Monday 14 May 2007

The Austro-Asiatic linguistic family is considered to be the oldest of all the families in India, but it has a substantial presence in Southeast Asia.

There are three branches of Austro-Asiatic tribes: Mundari, Khasi-Khmuic and Mon-Khmer.

It has been suggest a strong paternal genetic link, not only among the subgroups of Indian Austro-Asiatic populations but also with those of Southeast Asia. However, maternal link based on mtDNA is not evident. (17389048)

The haplogroup O-M95 had originated in the Indian Austro-Asiatic populations 65,000 yrs BP (95% C.I. 25,442-132,230) and their ancestors carried it further to Southeast Asia via the Northeast Indian corridor.

Subsequently, in the process of expansion, the Mon-Khmer populations from Southeast Asia seem to have migrated and colonized Andaman and Nicobar Islands at a much later point of time.

The linguistic ancestors of the Austro-Asiatic populations have originated in India and then migrated to Southeast Asia. (17389048)
