According to Davidski the author and owner of Eurogenes, some Gonds from Central India are almost pure AASI genetically. They can be even more AASI than the Paniya. These Gonds (Gond1 and Gond2 samples in G25 spreadsheet i believe) are less than 20% West Eurasian genetically, being closer to 15% which is a lot less than the Paniya.
He is referring specifically to the sample Gond1 and maybe Gond2 in G25 spreadsheet: https://drive.google.com/file/d/1FSzKKknFGcOgfyA76q9PD7B-n-MJs7L8/view?usp=sharing
Altho the Bonda and Juang might be even less Western admixed than these Gonds because they also have Mongoloid admix which can lessen a lot of the amount of Iran Neo and ANE in them.

Quoting Davidski
I have a couple of Indian samples in my dataset that are almost pure ASI, and they show very little BE ancestry. Only a few per cent.
They're Gonds from South Central India, probably with less than 20% West Eurasian admixture of any type. So almost purely East Eurasian in a broad sense, and with less than 10% BE.
They're the best proxies for ASI in almost all South Asians, except those with a lot of East Asian admixture.
Well many Gonds have a lot more than 20% West Eurasian admixture, and even some steppe admixture. I'm talking about a couple of individuals who show only about 16% Iran_N ancestry, plus another 5-6% or so of something related to AG3 and MA1, but not steppe admixture.
I think the AG3/MA1 stuff is just the algorithm correcting for the fact that there are no perfect references for ASI in my dataset, so I'd say that these Gonds have less than 20% West Eurasian admixture, and even a part of their Iran_N signal might really be ASI.
I don't know what they look like though
I'm talking about Gond1 in the G25 spreadsheet:

I can't really say anything useful about the Taforalt genomes until I've had a chance to analyze them.

Paniya have about 30% West Eurasian admixture. The reason they appear to be the most ASI population in the Basu paper is because they carry the most South Asian-specific drift, so they create a South Asian cluster which masks West Eurasian admixture. At the same time, Indian groups that don't share so much of this drift, but which are more ASI than Paniya, end up looking less South Asian and more East Asian.
This is one of the problems of relying too much on ADMIXTURE output.
Thoughts on this? Looks like we found one of the closest modern pops to pure blood AASI. It would be cool if they are more AASI than even the Paniya.
