I have commented extensively on the “Aryan” migration theory over the years. My well-researched position has been that:
a) Archaeological evidence points 100 per cent to inflow of “foreign” migrants into India (e.g. see this blog post)
b) Linguistic evidence is overwhelmingly clear (100 per cent) that modern Indian languages (including Sanskrit) came to India from outside (e.g. see this post). Attempts to suggest that Sanskrit originated in India result in pure gibberish (e.g. see this post, this one, and this one [My analysis disproves the “Out of India” theory of the recent Hindutva fanatics]
c) DNA evidence has been relatively unclear so far but the science is very new and surely more will be learnt soon.
Now, even DNA evidence has become very clear. This article confirms it.
R1a is distributed all over Europe, Central Asia and South Asia; its sub-group Z282 is distributed only in Europe while another subgroup Z93 is distributed only in parts of Central Asia and South Asia; and three major subgroups of Z93 are distributed only in India, Pakistan, Afghanistan and the Himalayas. This clear picture of the distribution of R1a has finally put paid to an earlier hypothesis that this haplogroup perhaps originated in India and then spread outwards. This hypothesis was based on the erroneous assumption that R1a lineages in India had huge diversity compared to other regions, which could be indicative of its origin here. As Prof. Richards puts it, “the idea that R1a is very diverse in India, which was largely based on fuzzy microsatellite data, has been laid to rest” thanks to the arrival of large numbers of genomic Y-chromosome data.
QED. The proofs are ALL clear now.
But note that I use the word Aryan in quotes. That is because I do not consider that the idea of “Aryan” is robust or well-defined enough in any meaningful way. What exactly is it? A cultural idea, a linguistic idea, a “race” idea? No one can say for sure.
All we can say at best is that FOREIGNERS from Central Asia (including from as close as Iran) came into India.
