Population genetics is an emerging field that’s shedding new light on ancient human migrations. It complements linguistics and archaeology, which have until now been the primary avenues for understanding prehistory. David Reich, a leading geneticist and a Harvard professor, has taken special interest in the much contested issue of the original homeland of Indo-European (IE) languages and the mixing of populations in India. Watch a video conversation with him on the edge.org page below (also transcribed).
Nothing Reich says will comfort the “out-of-India” theorists, largely a Hindutva brigade of “scholars” who claim that there was no Aryan migration into India; that instead a migration happened from India to Europe; that IE languages originated in the Indian Subcontinent from a proto-Sanskrit; that the people of the Indus Valley Civilization spoke this proto-Sanskrit (never mind that their script remains undeciphered; there’s no consensus on whether it is even a linguistic script); that the Vedas are wholly indigenous in inspiration, etc. It’s amazing how many people on the Internet confidently assert that the Aryan migration theory has been “discredited”.
Of course much of this was/is nationalistic windbaggery, based on wishful thinking and gaps in rival theories, not on any solid evidence from linguistics or archaeology. Population genetics is now producing a clearer picture once and for all. But we’re not there yet, even though Reich’s work has bolstered the Kurgan hypothesis, which puts the IE homeland in the Pontic-Caspian steppe. Watch this field for more definitive revelations in the years ahead.
