I'm not denying that I2a is from the Cimmerians.
So the I2a Kurdish conversation is done we agree on where it came from.
But I'm just saying that Cimmerians were not really Iranic people.
true but they defintley could have been. They lived right next to the iNdo Iranien sythiens and had similar culture and where described as light haired like sythiens and tocherians and early indo Iranian remains and not like modern people in that area.
Also, who's saying that the mummies in Central Asia are (proto-)Indo-Iranian? And about which mummies are you actually talking about?
The Andronovo, Afanasvo, and sintashta cultures where very very early Indo Iraniens. the Tarium mummies some are 4,000 years old they where a mix of European and east asian the european came from the first Indo iranien speakers because they came from russia. 4,000 years ago is before Indo Iranians ever came to India so why where they in west china before india if they migrated from the caucus through iran.
If you mean those Scythian mummies, Scythians were NOT Indo-Iranian at all. Indo-Iranians lived thousands of years before the Scythians. Scythians were actually (modern) Iranic tribes HEAVELY mixed with the NATIVE Steppes peoples!
Sytheins where Indo iranien this has been known from historian since like the 1800's. We know this because of some writting we have of their language., Their culture decends from Indo iranien cultures that existed in asia 2,000 years before them. Also we have Y DNA, mtDNA, hair color, and eye color from tagar sytheins and indo iraniens from 4,000 and 3,800ybp all of those actgories where a match so we pretty much know for a fact sytheins where indo iranien.
I dont now what u mean by modern Iranic tribes if u mean iran sytheins where nothing like modern iraniens. Phiscalley they where white and had mainly blonde hair and light eyes and where also known for red hair. There is no doubt in the world that they originally genetically came from Europe. They stayed did not inetr marry a whole lot with other people because DNA from Adrnovo culture from 3,800ybp had nearly identical Y DNA, mtDNA, hair color, and eye color to less than 2,000 year old Sythein remains so for about 2,000 years they almost did not inter marry at all.
But the ones in chian and siberia inter married a ton that is why tarium mummies had mtDNA C4 and alot of black hair(almost no European, mid easterns, and north africans have true black hair). Also why R1a still exists at over 40% in south siberia today. Also sytheins and other Indo Iranians where almost completely killed off by migrating Turkic trbes from eastern asia about 2,000-2,500ybp.
