    R1a-Y7 in South Asia

    So, I just found out my Y-DNA is R1a1a1b2a1a, aka R1a1a-Y7. So, is there any info regarding this haplogroup and its distribution among Z93ers/South and Central Asians? Which "culture" does it originate from?

    R1a-Y7 is today most common in South Asia (India, Pakistan, Bangladesh, Sri Lanka, Afghanistan) but exists in smaller frequencies also in Arabic countries, Iran, Tajikistan, West China (Uyghurs) and Central Asia. Y7 was also found among one Tatar in Russia and some Kazakhs. In Europe Y7 and the parallel Y6 seem to be absent today (excluding South Asian-derived Romani people). Y6 which is like Y7 also derived from R1a-L657 seems to have also the same distribution but the Y6/Y7 ratio tends to get higher in South and East India.

    R1a-Y7 and Y6 are downstream markers of L657 and this lines were not found yet in ancient dna (excluding the Y6 in Roopkund but this is a fairly recent sample only 1000 years old). But Y3 upstream of L657 was found in Sredny Stog and Z2124 which is parallel of Y3/L657 was found in Sintashta/Andronovo so we can assume that early L657 was quite similar to this Sintashta and Sredny Stog samples. They were mainly derived from Eneolithic Pontic-Caspian steppe groups but carried significant Central European Farmer (GAC,..) admixture. This groups probably spoke some late Proto-Indo-European and became agro-pastoralists which later dominated the steppes. So Y7 ultimately orginates from Neolithic/Bronze Age East Europe but where it exactly was born is not clear yet.

    Y3 ancestral to L657 and Y7 was also found among one Ukrainian cossack. So despite L657/Y7 being absent in Europe. Ancestral Y3 is still found in Europe

    Welcome to the club brother. Y7 Y2568* here. My clad seem to be shared with a Saudi and Pakistani Punjabi. Why don't you take R1a superclade test from YSEQ? It'd be awesome if you turn out to be it.

    Y3 probably predates the formation of Indo-Iranians if it is correct that it was found in Sredny Stog. So not all Y3 carriers must be descendants of Indo-Iranians. Y3* was also found among a Saudi and Kazakh but based on what we know about ancient Indo-Europeans it is unlikely that Y3 was born in West or Central Asia.

    There's also a Y3* sample on YFull from Brazil, which is certainly European, so that's yet more evidence that suggests Y3 originated somewhere in or around the Sredny Stog region.
