Nature are really crap at geography. Obviously, this paper argues that modern domestic horses came from the Pontic-Caspian steppe, which is located very firmly in Eastern Europe. But, inexplicably, instead of actually saying this, the authors came up with the much more ambiguous term Western Eurasian steppes, and even put that in the title. I wonder why? Here's the paper abstract:
Domestication of horses fundamentally transformed long-range mobility and warfare 1. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling 2,3,4 at Botai, Central Asia around 3500 bc3. Other longstanding candidate regions for horse domestication, such as Iberia 5 and Anatolia 6, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes [my note: they actually mean the Pontic-Caspian steppe, which is located in Eastern Europe], especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association 7 between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe [my note: the Yamnaya culture was located in Europe] around 3000 bc 8,9 driving the spread of Indo-European languages 10. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture 11,12.

Update: I emailed one of the lead authors, Ludovic Orlando, asking him for a comment. Here it is:
Thanks for your interest in our research. We indeed struggled finding the term that would be most appropriate and this was discussed with our coauthors. The Pontic-Caspian steppe would seem the most obvious choice but my understanding is that this would include a large region, stretching from the most north-western side of the Black sea to the foothills of the Urals. This is larger than the signature recovered in our data. My understanding is that the Eastern European steppes would also stretch more northernly than the region that we narrowed down. Eastern European steppes was also not immediately clear, even for European scholars such as myself. Therefore, it did not seem that there were any terms that were ready-made for truly qualifying our findings. We thus went for Western Eurasian steppes in the main title, and sticked to more precise locations such as the Don-Volga region in the main text. I guess that this is one of those cases where the activities of past herders did not exactly follow some geographic terms that would only be defined thousands of years later.
However, the Pontic-Caspian steppe and the Eastern European steppe are in fact terms that describe the western end of the Eurasian steppe. So they should be totally interchangeable with the term Western Eurasian steppes. Except, at least to me, they seem less ambiguous.
Ergo, the Eastern European steppe can't be more northerly than the Western Eurasian steppes, because it's the same thing. Moreover, the Pontic-Caspian steppe can't stretch further west than the Western Eurasian steppes, because, again, it's the same thing.
Indeed, the land north of the Eastern European/Western Eurasian steppes is called the forest steppe.
