An Iranian from 1800 BCE.
New post on my blog where I look at a sample from 1800 BCE Uzbekistan that contains the 3 way mix of modern West Iranians (Steppe + BMAC + Chalcolithic farmer). This sample can be used to model modern Iranians quite well.

@razibkhan @blog_supplement had discussed the Sappali Tepe outlier a while ago, it gives very decent fits on modern Iranians and has around ~24-26% MLBA Steppe ancestry, the rest being BMAC + Chalco farmer + minor Indus.
Its dated to 2000-1600 BCE
@razibkhan @blog_supplement What does this show us? That the mix that characterizes modern Indians and Iranians had formed in Central Asia by 1800 BCE already. Whether this outlier spoke Iranic languages or not cannot possibly be known with certainty, but my opinion is he likely did.
@razibkhan @blog_supplement Interestingly, his haplogroup is Q1b2, which is an India specific branch of Q1 (found in the Swat Valley Loebanr samples) and this makes sense as he had 10% Indus Valley like ancestry.
This individual is a mix of West Iranian type farmers + early East Iranian (TKM_IA) type ancestry. Now, interestingly enough, this must mirror the actual process by which modern West Iranians came to be.
Steppe pastoralists mix with Turan_BA (BMAC) type people and form a hybrid 50:50 ish population in Central Asia. This population eventually comes down to the Iranian plateau and mixes with the native Elamite-type farmers to form modern West Iranians.
