The much-awaited DNA study of the skeletal remains found at the Harappan site of Rakhigarhi, Haryana, shows no Central Asian trace, indicating the Aryan invasion theory was flawed and Vedic evolution was through indigenous people.
“The Rakhigarhi human DNA clearly shows a predominant local element — the mitochondrial DNA is very strong in it. There is some minor foreign element which shows some mixing up with a foreign population, but the DNA is clearly local,” Shinde told ET. He went on to add: “This indicates quite clearly, through archeological data, that the Vedic era that followed was a fully indigenous period with some external contact.”
I haven’t heard anything definitive, but this is what I have heard: that the genetics they could analyze indicates continuity, but none of the steppe element ubiquitous in modern North India (and that there was contamination in the Korean lab). The Rakhigarhi samples date to 2500 to 2250 BC last I checked. That means they shouldn’t have any steppe ancestry if the model of the relatively late demographic impact of Indo-Aryans after 2000 BC is correct.
Basically, the whole article is kind of a non sequitur. I do understand that many archaeologists think there was continuity culturally. And there could have been. But taking into account the genetics of the modern region of India where Rakhigarhi is located, there was a major demographic perturbation after 2250 BC.
