Waves of migration into South Asia

A lot of the Nairs and Kodavas have mtdna haplogroup U1a1c1d from the list you posted. Are there any ancients with this haplogroup? Is it AASI related?

Thanks. Do you know how much AASI that sample has?

About 15%


mt U falls to near 0 east of South Asia so I consider U overall to be a Iran N related mt line.
But because its presence is very old in South Asia, it must have admixed with its AASI counterparts quite early.
Even the Rakhigarhi woman's U2b2 line is over 20000 years old

Around 41.5% (22/53) of Koraga tribals are U1 according to this study - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC516768/

It's probably widespread among Dravidian speakers.

Apparently there are some upcoming samples from Tamil Nadu dating to around 300 AD/CE. Hopefully they will be out at some point this year.

Yes I was expecting to see some PGW analysis too. I think PGW will show some steppe in the range of the Swat valley samples, but looks like the major steppe influx is in the Kushan period.

Some notes:
1. Bali - 6th 7th century bc ancient sample matches with present Orissa and then with Tamil Nadu - connection perhaps goes back earlier.
2. Ancient Ahom show strong connection with present Thailand.
3. IVC >2000 BC Rakhigarhi = present Andaman like + ancient Iranian like.
4. Sinauli circa 2000 BC - clearly no steppe, but overall a poor sample.
5. Kashmir - no steppe circa 1500 BC, but ~200 AD - steppe rich.
6. Tamil Nadu ~300 BC - ancient samples close to modern populations - but no steppe ancestry.
7. Naga hills 3000-4000ybp - unlike at present no 'Han' ancestry seen, but like at present ancestry connection with Burma and Tibet.

In line with the the Protohistoric Period Cambodia sample.
"all these surrogates are from Southern India (Fig. 1), and the fraction of Southern Indian ancestry was estimated at 42–49% across all plausible qpAdm models"

Contrary to earlier findings, in that video, he says Rakigarhi lady has over 40% Andamanese-related ancestry. I knew then they probably had actual AASI samples for this sudden reverse. A couple of months later, they released the mtdna study of those two Srilankan samples. He says her Iranian related ancestry is 30-40%, Andamanese related around 40-50%, and the rest I am assuming is ANE related ancestry.

Possible, but I get the feeling when I hear Rai talk that he just throwing around those percentages without much exactitude.
For the Rakhigarhi sample, the calculations were done by Patterson and Narasimhan, and the paper was written by Reich and Narasimhan.

He said 50% in the video, but she is closer to 40%

Any link to this particular video? thanks

EDIT- no worries, I think I found it, the Pondy lecture one.
