The "Gedrosian" or "South Asian" being seen in Steppe is because "South Asians" and "Gedrosians" are largely descended from CHG like people. I don't know why this modern population that happens to be embedded in the computational models is being used in the way it is on these boards.
Than you haven't been following this discussion. For the point of determining how much ancestry an ancient people have contributed to a modern population and see to with which modern populations it shares how much ancestry, it is indeed important to include these modern populations in this discussion. We aren't talking about the Scythian ancestry here you have missed the point. If that was the case we would solely speak of CHG, EHG, EF. But we aren't soleley discussing the Scythian ancestry, we are discussing the ancestry of modern Iranic speakers and their relationship to this Scythian samples. Also it is important and interesting in this case to see, IF we had to explain the ancestry of modern Scythians based on modern populations we would need to use a mixed West_South_Central Asian and East European example, cause Scythians as also seen on PCA plots (and this is not due to projection bias as some "experts" with an agenda would claim, cause obviously the Scythian samples have some ancestry only found in significant frequency in West_Central Asians such as allot more CHG like ancestry, some East Eurasian (depending on the Scythian sample from 0-20%, 10-20% is typical Tajik). Than they have higher frequency of EHG compared to West_Central Asians. At last there is EF which both groups- West_Central Asians as well East Europeans share in similar amount.
Therefore the Scythians appear as they appear and plot as they plot.
