Modern Horses were domesticated in Europe

I've been waiting for some concrete DNA evidence about where modern horses came from since I interviewed Alan Outram three years ago and he hinted that it was soon to be published. He indicated that Sintashta horses might end up being more important than Yamnaya ones, and now that the new paper, to which he contributed, has finally been published, I can see why.

 

The new paper (Librado et al 2021) doesn't make the findings very clear IMO (refers to Europe as West Eurasia and makes the contested assumption that Corded Ware was descended from Yamnaya) but it does answer some important questions. I will summarise the findings in a clear TLDR bullet point list below:

• Botai may have been first to corral horses for milking but they didn't ride them.

• Yamnaya kept horses for milking too but we cannot see if they were ridden (However Trautmann et al 2023 shows Yamnaya did ride them)

• Wilkin et al (2021) looking at milk proteins in pottery agrees with this new paper regarding "a potential epicentre for horse domestication in the Pontic–Caspian steppe by the third millennium BC" = Yamnaya.

• Librado et al (2021) points to Volga-Don region (aka Yamnaya EUROPE) as the homeland of modern domestic horses

• Sintashta horses (DOM2) were superior for riding (stronger backs) and replaced earlier ones from 2200 BC

• Sintashta horses (DOM2) had genetic continuity with earlier Yamnaya /Repin ones (TURG) and Steppe Maykop (Aygurskii), and Poltavka (Sosnovka) - specifically two late Yamnaya specimens from approximately 2900 to 2600 BC

• Yamnaya horses had some relation, but not much, to Botai horses

• The Tarpan and modern Przewalski’s horses do not descend from the same ancestral population as modern domestic horses

• Modern horses were domesticated in Europe but the paper calls it West Eurasia - possibly as a deliberate, politically motivated obfuscation

• The ancestors of Sintashta horses came from the steppe East of the Dnieper and West of the Volga-Don region - ie: firmly within European Yamnaya territory during the late fourth and early third millennia BC

• Corded Ware horses were not the same as Yamnaya/Sintashta horses 

• Earlier LBK and other Neolithic horses in Denmark, Poland, Czechia and Hungary had some affinity with Yamnaya/Sintashta horses - the geneflow seems to have been via Thrace

• Corded Ware expansion into Europe was not accompanied by horses but rather they adopted local horses as they migrated (not clear if they were ridden)

• Replacement of other horse lineages in Europe and Asia by Sintashta ones was accompanied by spread of both equestrianism and (a bit later) light two wheeled war chariots

• The spread of Sintashta horses into the middle east was likely accompanied by the spread of a specialised class of Sintashta descended horse trainers like the Mitanni.

Sintashta were a people of European origin and their horses came from Yamnaya horses and Yamnaya domesticated their horses in Europe (see Robert Molyneaux's forensic reconstruction of a Yamnaya male above). Reminder that Sintashta, despite being Proto-Indo-Iranic speakers, the descendant languages of which are now found in Iran and India, were white people. So it is accurate to say that white people gave modern domestic horses to the world. Below are some reconstructions of Sintashta men by "ancestral whispers".

All this new information should be considered when we examine the evident Indo-European origin of horse sacrifice which I discussed at length in a documentary film on the subject.

EDIT: A new paper from March 2023 presents biological evidence that Yamnaya rode horses and they were the first to do so. So Europeans really were the first horse riders ever.
