Admixture between EHGs and CHGs is believed to have occurred on the eastern Pontic-Caspian steppe starting around 5,000 BC, while admixture with Early European Farmers (EEF) happened in the southern parts of the Pontic-Caspian steppe sometime later.

Then came the Caucasian Hunter-Gatherer (CHG) admixture, making up about 15-25% of their genomes. This admixture is mainly associated with Y-haplogroup J, and indeed one J* sample was found in Mesolithic Russia.

Admixture proportions of Yamnaya populations. They combined Eastern Hunter Gatherer ( EHG), Caucasian Hunter-Gatherer ( CHG), Anatolian Neolithic ( ) and Western Hunter Gatherer ( WHG) ancestry.

Aug 5, 2019 · We observed the most significant signals of admixture in the Shirenzigou samples when using Yamnaya_Samara or Srubnaya as the West Eurasian source and some Northern Asians or Koreans as the East Eurasian source (Table S1).

Feb 11, 2017 · If the steppe or Kurgan PIE hypothesis is correct, then we'd expect this to have happened during the Bronze Age rather than, say, the Medieval Period with the migrations into Iberia of Northern Europeans likely rich in Yamnaya-related admixture like the Visigoths.

Aug 5, 2019 · Without any doubt, a CHG population that was not admixed with Anatolian Farmers mated with EHG populations in the Volga steppes and in the North Caucasus steppes before 4500 BC. We can refer to this admixture as pre-Yamnaya, because it makes the best currently known genetic ancestor for EHG/CHG R1b Yamnaya genomes. From Wang et al (2019):

Sep 11, 2019 · The BMAC-related admixture in Kazakhstan documents northward gene flow onto the Steppe and confirms the Inner Asian Mountain Corridor as a conduit for movement of people. Similar to how the Sintashta_MLBA_o2 cluster shows an admixture with central steppe populations and hg.

Oct 3, 2018 · Recent genomic studies have revealed cross-continental Early Bronze Age migrations (~3000 BCE) of the nomadic people associated with the Yamnaya horizon (3, 4). The migration introduced the Caucasus genetic component to the genetic landscape of Europe.

Feb 5, 2025 · Around 5,000 years ago, pastoralists of the Yamna, or Yamnaya, culture from the Pontic–Caspian steppe, which spans eastern Europe and central Asia north of the Black and Caspian seas, rode west...

Jul 25, 2019 · Here, we report the first genome-wide data of 10 ancient in- dividuals from northeastern Xinjiang. They are dated to around 2,200 years ago and were found at the Iron Age Shirenzigou site. We find...
