The intrusive Indo-Aryans had a huge demographic impact on South Asia

Is there a way to estimate the actual Indo-Aryan contribution?

Could the Iranian related ancestry further north and west be separated from the newly discovered ‘native Indian’ iranian related ancestry?

Re: SCIENCE Paper

Another controversial genetics paper (coincidentally?) in only two days. Again the same boring and meaningless ‘steppe, Indo-European, baltoslavics, etc’. Let see the first sentence in Conclusion:

“CONCLUSION: Earlier work recorded massive population movement from the Eurasian Steppe into Europe early in the third millennium BCE, likely spreading Indo-European languages. We reveal a parallel series of events leading to the spread of Steppe ancestry to South Asia, thereby, documenting movements of people that were likely conduits for the spread of Indo-European languages.”

>>> This paper contradicts the CELL paper regarding the migration and spreading the ‘steppe’ ancestry to SA. It mentioned a CONDUIT for the spread of IE languages!!! Which languages, what does it mean, conduits? Is it something as Latino-Americans spreading the Spanish language (and genes) through the conduits under the Trump’s wall?

What the diagram says? The migration from Yamnaya to Europe started in 3300BC carrying IE languages? What about Lepenski Vir (9500-7200BC) and Vinca civilisations (5700-4500BC)? If you use a microscope you can see that ‘steppe’ migration came just meters (from other side of Danube) from these places. Migrations brought IE languages (which?) while In Vinca already had the alphabet for almost 2000 years. Which language was spoken in Vinca, which is this alphabet, time counting (now the year 7528), first wheel and thousands of other things which can be seen on wiki?

Reich knows this because he wrote a paper about Lepenski Vir last year. They say that ‘hunter-gatherers’ lived in Lepenski Vir? LV is called ‘the first city in the world’ with one main settlement and 10 satellite ‘suburbs’, already developed trades, solid and planned houses which survived for thousands of years, etc. How likely that was the place of ‘hunter-gatherers’? Maybe, HG subset – ‘fishermen-catchers’?

Diagram also says:
“Location of the initial formation of Yamnaya ancestry is uncertain.”
“2000BC: Path by which this ancestry arrived in South Asia is uncertain.”

>>>They don’t know when the Yamnaya was formed (!) and how (which conduit?) they came to SA (!). Wow!

Finally, in the paper:

“Using data from ancient individuals from the Swat Valley of northernmost South Asia, we show that Steppe ancestry then integrated further south in the first half of the second millennium BCE, contributing up to 30% of the ancestry of modern groups in South Asia. The Steppe ancestry in South Asia has the same profile as that in Bronze Age Eastern Europe, tracking a movement of people that affected both regions and that likely spread the unique features shared between Indo-Iranian and Balto-Slavic languages.”

>>> Ok, this something – genes of Eastern Europe (which one, who are they?) are the same as in South Asia.

This thing about Indo-Iranian and ‘balto-slavic’ languages we can ignore because it does not say and mean anything…… Conduits? (ha-ha-ha).

The whole talk about IQ genes is purely speculatory. We don’t even have a full list for them yet let alone the ability to look for it in the damaged ancient DNA. Also, how would you explain people with higher EHG and lower CHG ancestry like Finns being smarter than other Europeans (on average) who have more CHG (in relation to the EHG ancestry among them)? Granted, Finns also seem to have a lower SD/variation when it comes to this characteristic (which may have something to do with lower stratification in the past and more significant effects of a bottleneck).

As far as MLBA admixture is concerned, the Sikh Jat value in Narasimhan’s paper is roughly similar to what happens when you use Shahr BA1 + Shahr BA3 + Krasnoyarsk + extra Paniya to model them. The same combination results in the UP Jats being around 35% Krasnoyarsk. The number of UP Jats in the set was around 2 in total- so its not a very big set (which could be an issue in of itself), but eastern Jats have shown the tendency to have a higher steppe and the NE Euro admixture than their Sikh counterparts. I wouldn’t be surprised if they truly were between 30% to 35% Krasnoyarsk on average.

So we’re more sons of Indus than sons of Indra eh?
