As Corded Ware and Yamnaya peoples both almost certainly spoke | Αρυολογία☀️ (The Indo-Europeans)

As Corded Ware and Yamnaya peoples both almost certainly spoke variants of the same Proto-Indo-European language cluster, and were 80–100% genetically alike, it is logical to assume a common ancestral tribe for them. This can be found amongst the pre-Yamnaya kurgan cultures of the late-Neolithic Steppe, such as Sredny Stog (4500 – 3500 BCE), the Khvalynsk Culture (4900 – 3500 BCE) and, ultimately, the Samara Culture (5th millennium BCE) of the Pontic-Caspian Steppe.

This is also substantiated by the archaeological evidence of these pre-Yamnaya Steppe cultures consisting of tumuli (burial mounds), red ochre and horse sacrifice, amongst other funerary rites consistent with Proto-Indo-European language and culture. See:

Khvalynsk: The First Kurgans? https://t.me/Aryologia/2064

It is also the case that many Corded Ware DNA samples contain admixture from non-Steppe populations of Europe, while in Yamnaya such mixture is minimal. This suggests a more eastward origin of the Corded Ware population, indicating mobility from an original homeland to northern Europe.

Bottom Line: in conclusion, this changes little about what we thought we knew of Indo-European ethnogenesis. The source of Indo-European languages generally, remains the Pontic-Caspian Steppe of the late-Neolithic era, while the Western Steppe Herder (or, "Yamnaya-like") ancestry found in modern-day speakers of Indo-European languages can still be traced to the mixing of Eastern Hunter-Gatherers and Caucasus Hunter-Gatherers at a point in time prior to the emergence of the first kurgan cultures.

The Proto-Indo-European Urheimat was not the northern European Corded Ware region.
