The genetic formation of Central and South Asian populations has been unclear because of an absence of ancient DNA. [...] Key Result We document a southward spread of genetic ancestry from the Eurasian Steppe, correlating with the archaeologically known expansion of pastoralist sites from the Steppe to Turan in the Middle Bronze Age (2300-1500 BCE).Expand
The formation of human populations in South and Central Asia
TLDR
It is shown that Steppe ancestry then integrated further south in the first half of the second millennium BCE, contributing up to 30% of the ancestry of modern groups in South Asia, supporting the idea that the archaeologically documented dispersal of domesticates was accompanied by the spread of people from multiple centers of domestication. Expand
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. Expand
The genetic history of admixture across inner Eurasia
TLDR
Genome-wide data for 763 individuals from inner Eurasia reveal 3 admixture clines in present-day populations that mirror geography, illuminating the historic spread and mixture of peoples across the Eurasian steppe, taiga and tundra. Expand
The genetic makings of South Asia.
TLDR
Current studies on natural selection in South Asia have so far revealed strong signals of sweeps that are shared with West Eurasians, but future studies will have to fully unlock the aDNA promise for South Asia. Expand
Characterizing the genetic history of admixture across inner Eurasia
TLDR
The genetic structure of Caucasus populations highlights a role of the Caucasus Mountains as a barrier to gene flow and suggests a post-Neolithic gene flow into North Caucasus populations from the steppe. Expand
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. Expand
The Genetic Ancestry of Modern Indus Valley Populations from Northwest India.
TLDR
New genome-wide genotype data for 45 modern individuals from four Northwest Indian populations, including the Ror, are reported, showing that the Indus Valley populations are characterized by considerable genetic heterogeneity that has persisted over thousands of years. Expand
Historic migration to South Asia in the last two millennia: A case of Jewish and Parsi populations
TLDR
In this study, a broad genetic profile of Indian Jews and Parsis is reconstructed to paint a fine-grained picture of these ethnic groups. Expand
Ancient Genomes Reveal Yamnaya-Related Ancestry and a Potential Source of Indo-European Speakers in Iron Age Tianshan
TLDR
A Western Eurasian steppe origin for at least part of the ancient Xinjiang population is suggested, and a Yamnaya-related origin for the now extinct Tocharian languages in the Tarim Basin, in southern Xinjiang is supported. Expand
Ancient genomes reveal complex patterns of population movement, interaction, and replacement in sub-Saharan Africa
TLDR
The contraction of diverse, once contiguous hunter-gatherer populations in sub-Saharan Africa is demonstrated, and the resistance to interaction with incoming pastoralists of delayed-return foragers in aquatic environments is suggested. Expand

The Genomic History of Southeastern Europe
TLDR
It is shown that southeastern Europe continued to be a nexus between east and west after the arrival of farmers, with intermittent genetic contact with steppe populations occurring up to 2,000 years earlier than the migrations from the steppe that ultimately replaced much of the population of northern Europe. Expand
Genomic insights into the origin of farming in the ancient Near East
We report genome-wide ancient DNA from 44 ancient Near Easterners ranging in time between ~12,000 and 1,400 bc, from Natufian hunter–gatherers to Bronze Age farmers. We show that the earliestExpand
Early Neolithic genomes from the eastern Fertile Crescent
TLDR
It is concluded that multiple, genetically differentiated hunter-gatherer populations adopted farming in southwestern Asia, that components of pre-Neolithic population structure were preserved as farming spread into neighboring regions, and that the Zagros region was the cradle of eastward expansion. Expand
The genetics of an early Neolithic pastoralist from the Zagros, Iran
TLDR
It is shown that Western Iran was inhabited by a population genetically most similar to hunter-gatherers from the Caucasus, but distinct from the Neolithic Anatolian people who later brought food production into Europe. Expand
Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans
TLDR
The findings reveal that western Eurasian genetic signatures in modern-day Native Americans derive not only from post-Columbian admixture, as commonly thought, but also from a mixed ancestry of the First Americans. Expand
Reconstructing Indian Population History
TLDR
It is predicted that there will be an excess of recessive diseases in India, which should be possible to screen and map genetically and is higher in traditionally upper caste and Indo-European speakers. Expand
Ancestry and demography and descendants of Iron Age nomads of the Eurasian Steppe
TLDR
Genomic inference reveals that Scythians in the east and the west of the steppe zone can best be described as a mixture of Yamnaya-related ancestry and an East Asian component, and finds evidence that significant gene-flow from east to west Eurasia must have occurred early during the Iron Age. Expand
The Beaker Phenomenon and the Genomic Transformation of Northwest Europe
TLDR
Genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans is presented, finding limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and excludes migration as an important mechanism of spread between these two regions. Expand
An early modern human from Romania with a recent Neanderthal ancestor
TLDR
DNA from a 37,000–42,000-year-old modern human from Peştera cu Oase, Romania is analysed, finding that on the order of 6–9% of the genome of the Oase individual is derived from Neanderthals, more than any other modern human sequenced to date. Expand
Genetic evidence for recent population mixture in India.
Most Indian groups descend from a mixture of two genetically divergent populations: Ancestral North Indians (ANI) related to Central Asians, Middle Easterners, Caucasians, and Europeans; andExpand
