An Indian nationalist named Kazim writes:
Out of India theory is quite possible and its pretty much can be proven by DNA.
Haplogroup R1a (Y-DNA) which is carried by most Eastern Europeans [Slavs] originated in South Asia, in modern day Indian states Uttar Pradesh and Punjab [ including Pakistan] and Highest frequencies are for it in found in India and Eastern Europe and certain population of Western Europe..
R1a in South Asia has the highest level of diversity of Y-STR haplotype variation within R1a1a compared to Eastern or Western Europe.
Haplogroup R1b (Y-DNA) Which is carried by most Western Europeans originated in Western Asia [ in Anatolia modern day Turkey] and also has high frequencies among certain Central Asian Turkic population and Hazara population of Afghanistan.
Also both DNA are found in low frequencies in Central Asia unlike in South Asia and Eastern Europe.
I don’t see what R-1b has to do with the argument, other than a suggestion that the actual homeland of Indo-European is in Anatolia, a controversial theory that I believe in.
R1a appears to have originated in the I-E Urhmeit of Southern Russia and the Southern Urals. A main branch went to North India with the Aryans. The reason their levels are so high is not because IE originated in India but due to a founder effect of large numbers of the original R1a group going to North India. A lesser group went to the Slavic regions, so they also have some R1a.
The Out of India theory of IE is so preposterous that it is rejected by all academics working in the field. A major journal’s decision to publish an issue on the theory met with widespread protest for publicizing a nonsensical theory.
