The indigenous populations of inner Eurasia, a huge geographic region covering the central Eurasian steppe and the northern Eurasian taiga and tundra, harbor tremendous diversity in their genes, cultures and languages. In this study, we report novel genome-wide data for 763 individuals from Armenia, Georgia, Kazakhstan, Moldova, Mongolia, Russia, Tajikistan, Ukraine, and Uzbekistan. We furthermore report genome-wide data of two Eneolithic individuals (∽5,400 years before present) associated… 
Ancient human genome-wide data from a 3000-year interval in the Caucasus corresponds with eco-geographic regions
TLDR
The authors generate genome-wide SNP data for 45 Eneolithic and Bronze Age individuals across the Caucasus, and find distinct genetic clusters between mountain and steppe zones as well as occasional gene-flow.
The genetic prehistory of the Greater Caucasus
TLDR
The steppe groups from Yamnaya and subsequent pastoralist cultures show evidence for previously undetected farmer-related ancestry from different contact zones, while Steppe Maykop individuals harbour additional Upper Palaeolithic Siberian and Native American related ancestry.
Paleo-Eskimo genetic legacy across North America
TLDR
It is shown that Paleo-Eskimo ancestry is widespread among populations who speak Na-Dene and Eskimo-Aleut languages, and a comprehensive model for the complex peopling of North America is presented.
Populations dynamics in Northern Eurasian forests: a long-term perspective from Northeast Asia
Abstract Abstract The ‘Northern Eurasian Greenbelt’ (NEG) is the northern forest zone stretching from the Japanese Archipelago to Northern Europe. The NEG has created highly productive biomes for
Early nomads of the Eastern Steppe and their tentative connections in the West
Abstract Abstract The origin of the Xiongnu and the Rourans, the nomadic groups that dominated the eastern Eurasian steppe in the late first millennium BC/early first millennium AD, is one of the
Bronze Age population dynamics and the rise of dairy pastoralism on the eastern Eurasian steppe
TLDR
Investigation of a putative early pastoralist population in northern Mongolia finds that dairy production was established on the Eastern steppe by 1300 BCE, suggesting that ruminant dairy pastoralism was introduced by local hunter-gatherers through a process of cultural transmission and minimal genetic exchange with outside groups.

The Genomic Formation of South and Central Asia
TLDR
The results show how ancestry from the Steppe genetically linked Europe and South Asia in the Bronze Age, and identifies the populations that almost certainly were responsible for spreading Indo-European languages across much of Eurasia.
Between Lake Baikal and the Baltic Sea: genomic history of the gateway to Europe
TLDR
This project has patched the hole in the genetic map of Eurasia by demonstrating complexity of genetic structure of Northern Eurasians, existence of East-West and North-South genetic gradients, and assessed different inputs of ancient populations into modern populations.
Genome-Wide Diversity in the Levant Reveals Recent Structuring by Culture
TLDR
The results show recent genetic stratifications in the Levant are driven by the religious affiliations of the populations within the region, and Levant populations today fall into two main groups: one sharing more genetic characteristics with modern-day Europeans and Central Asians, and the other with closer genetic affinities to other Middle Easterners and Africans.
A major Y-chromosome haplogroup R1b Holocene era founder effect in Central and Western Europe
TLDR
Within the M412 dichotomy, the major S116 sub-clade shows a frequency peak in the upper Danube basin and Paris area with declining frequency toward Italy, Iberia, Southern France and British Isles, and more complex pre-Neolithic scenarios remain possible for the L23(xM412) components in Southeast Europe and elsewhere.
Genetic differentiation between upland and lowland populations shapes the Y-chromosomal landscape of West Asia
TLDR
This work sequenced a large portion of the Y-chromosome in haplogroup R1b samples from present-day East European steppe populations, showing that the paternal descendants of the Yamnaya still live in the Pontic steppe and that the ancient YamNaya population was not an important source of paternal lineages in present- day West Europeans.
The Genetic Legacy of the Expansion of Turkic-Speaking Nomads across Eurasia
TLDR
The results indicate historical admixture among Turkic peoples, and the recent shared ancestry with modern populations in SSM supports one of the hypothesized homelands for their nomadic Turkic and related Mongolic ancestors.
The population genomics of archaeological transition in west Iberia: Investigation of ancient substructure using imputation and haplotype-based methods
TLDR
Genome-wide imputation of a large dataset of ancient samples enabled sensitive methods for detecting population structure and selection in ancient samples and revealed subtle genetic differentiation between the Portuguese Neolithic and Bronze Age samples suggesting a markedly reduced influx in Iberia compared to other European regions.
Paleo-Eskimo genetic legacy across North America
TLDR
It is shown that Paleo-Eskimo ancestry is widespread among populations who speak Na-Dene and Eskimo-Aleut languages, and a comprehensive model for the complex peopling of North America is presented.
The Caucasus as an asymmetric semipermeable barrier to ancient human migrations.
TLDR
Autosomal genome variation in the Caucasus reveals significant genetic uniformity among its ethnically and linguistically diverse populations and is consistent with predominantly Near/Middle Eastern origin of the Caucasians, with minor external impacts.
