It is where the Yamnaya culture came out of around 3300-2600 BCE. A significant group due to their usage of domesticated horses and carts. They spread across much of Europe and central/South Asia, spreading the Proto-Indo European languages.
In Europe they largely displaced and/or assimilated the “Early European Farmers” and the remnants of the “Western Hunter Gatherers (although WHG appear to have been somewhat ancestral to the Yamnaya culture), although the degrees to which the admixture favors one group or the other varies depending on region.
The exact nature of the migrations and population dynamics are not certain and very fuzzy since we have limited archeological evidence and are largely reconstructing based on genetics and linguistics. But it’s pretty clear there was a migration out of the Pontic step around this time that had a significant impact across Europe, Central Asia, Persia/iran and the north of the Indian sub-continent.
