The genetic history of admixture across inner Eurasia
The genetic history of admixture across Northern Eurasia
The indigenous populations of the Northern Eurasia — a vast region spanning the Central Asian steppes, taiga, and tundra — demonstrate high diversity in genes, culture, and languages. The article presents new genomic data on 763 individuals from Armenia, Georgia, Kazakhstan, Moldova, Mongolia, Russia, Tajikistan, Ukraine, and Uzbekistan, as well as data on two ancient genomes of the Eneolithic Botai culture in Kazakhstan (5400 years ago). Modern populations in Northern Eurasia were discovered to be structured into three clines stretching from west to east, in mirroring the populations’ geography, and differing in the composition of the western and eastern genetic ancestral components. The Botai and more recent ancient genomes from Siberia show a decrease in contributions from so-called ‘ancient North Eurasian’ ancestry over time, which is detectable only in the most northern ‘forest-tundra’ cline. The intermediate ‘steppe-forest’ cline descends from the Late Bronze Age steppe ancestries, while the ‘southern steppe’ cline further to the south shows a strong West/South Asian influence. Ancient genomes indicate the spread to the north of the southern steppe cline in Central Asia during the first millennium BC. Finally, the genetic structure of the Caucasian populations exhibits the role of the Greater Caucasus Mountain Range as a genetic barrier and suggests a post-neolithic gene flow to the populations of the North Caucasus from the steppes.
