Exploring the sources of the 'Southern ancestry' in the Steppe

The proximal source of the southern (IranN/CHG) ancestry in the Eneolithic Steppe as well as Yamnaya populations has been a mystery. Chintalapati et al 2022 infer that the admixture between Eastern European Hunter-Gatherers and Iran Neolithic ancestry occurred between 4400-4000BCE, using the DATES algorithm developed by Moorjani Lab.

In this post, powered with newly published samples as well as better tools than before, I will attempt to decipher the true sources of these populations.

Disclaimer: The analysis presented below is based on the currently available published samples from the Pontic Caspian Steppe. The samples from the Middle Don region (Allentoft et al 2022 preprint) are unavailable, and this analysis will be updated once those samples become available.
