I'm guessing the steppe admix present in modern Sardinians came from the Roman colonists after the island was conquered.

In the Barbagia area, the steppe admixture is close to 0%, or even 0%. Also, yamnaya is pre-roman in some area of Sardinia...

Do you have see this sample with high WHG? 16.6/7% ! Even northern italian don't have it!!! And zero yamnaya!

Incroyable!

This is the most nuragh-like sample, typical a barbagian-like profil, central-like profil.

The Western Mediterranean Steppe paper had graphs showing steppe ancestry had arrived in Sicily by the Bronze Age but they couldn’t model modern Sicilians without adding substantial North African Neolithic

Modern Sardinians they show as 10% Steppe and Sicilians as 20% Steppe but here’s the problem. Problem is they as well as others as well as amateurs define Steppe as Yamnaya, saying if someone has Yamnaya genes then those are Steppe genes.

Problem is Yamnaya is EHG+WHG+CHG/Iran-N. Therefore if someone has Yamnaya’s WHG or CHG genes how do we know they came from Yamnaya (Steppe) or they came from other WHG or CHG non Steppe source.

Some will argue use EHG as Steppe proxy because it is more pure Steppe. But EHG is also ANE + WHG. WHG is non Steppe. So if someone has “EHG” genes how do we know it’s not the WHG part which they could have gotten from some WHG non Steppe decendant.

Therefore I think it’s better to use ANE as Steppe proxy since it’s has more real steppe genes than EHG and Yamnaya. If we do so we see that Steppe percentage in Europeans goes down and in West Asians goes up

Another good way to do this is using Dstats check to see how many Yamnaya genes Europeans and W. Asians have to the exclusion of WHG and CHG or use qpAdm and make sure WHG and CHG are included in outgroups

A much more simpler solution is just to use Corded Ware samples. Most of the Indo-European/Steppe admix in the world was spread by the culture derived from Corded Ware.
