Since the Bronze Age, pastoralism has been a dominant subsistence mode on the Western steppe, but the origins of this tradition on the Eastern steppe are poorly understood. Here we investigate a putative early pastoralist population in northern Mongolia and find that dairy production was established on the Eastern steppe by 1300 BCE. Milk proteins preserved in dental calculus indicate an early focus on Western domesticated ruminants rather than local species, but genetic ancestry analysis indicates minimal admixture with Western steppe herders, suggesting that dairy pastoralism was introduced through adoption by local hunter-gatherers rather than population replacement.

This population looks like Okunevo wich we already know had some mtdna linked with Yamnaya-Afanasievo. But Okunevo is almost 1000 years older, how this gap is possible? They didn't migrate south earlier? and why?

the 'eastern steppe' is more like a dry desert than a steppe

Yeah looks more like an arid plateau than proper temperate plains.
