Genome-wide patterns of selection in 230 ancient Eurasians

Ancient DNA makes it possible to directly witness natural selection by analyzing samples from populations before, during and after adaptation events. Here we report the first scan for selection using ancient DNA, capitalizing on the largest genome-wide dataset yet assembled: 230 West Eurasians dating to between 6500 and 1000 BCE, including 163 with newly reported data. The new samples include the first genome-wide data from the Anatolian Neolithic culture whose genetic material we extracted from the DNA-rich petrous bone and who we show were members of the population that was the source of Europe’s first farmers. We also report a complete transect of the steppe region in Samara between 5500 and 1200 BCE that allows us to recognize admixture from at least two external sources into steppe populations during this period. We detect selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height

The genetic history of the Southern Arc: a bridge between West Asia and Europe

By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe

Hayaz Höyük and the final PPNB in the Taurus foothills

In this paper differences of various aspects between Pre-Pottery Neolithic Hayaz and Pottery Neolithic Kumartepe are emphasized. Although these settlements are close in space and time, it seems that the Pottery Neolithic of the Taurus foothills owe little to the PPNB, especially where the chipped stone industry is concerned.Cette contribution porte sur les différents aspects qui séparent le site PPNB de Havaz du site de Kumartepe, lequel appartient au Néolithique à poterie. Bien que les deux sites soient proches dans l'espace et dans le temps, il semble que le Néolithique à poterie dans les contreforts du Taurus ne soit guère redevable à la tradition du PPNB, en particulier quant à son industrie lithique.Roodenberg Jacob.

Traces d'utilisation sur les haches polies de Bouqras (Syrie)

The Neolithic occupation of Tell Bouqras was located on the right bank of the Middle Euphrates valley, across from the junction with the Khabour. The village was occupied continuously from 6400 to 5900 B.C., and comprised about 180 houses, at its peak. A PPNB facies of chipped stone tools of flint, and, less commonly, obsidian, were found here, as well as many ground stone artifacts, including an esthetically-pleasing stoneware and rather abundant ground stone woodworking tools. Study of microtraces of use, along with observation of other attributes, proved to be useful in functional classification of the various ground stone tools. At least five distinct functional types were distinguished : felling axe, wedge, chisel, paring chisel and adze.Roodenberg Jacob J. Traces d'utilisation sur les haches polies de Bouqras (Syrie).

A genetic probe into the ancient and medieval history of Southern Europe and West Asia

Literary and archaeological sources have preserved a rich history of Southern Europe and West Asia since the Bronze Age that can be complemented by genetics. Mycenaean period elites in Greece did not differ from the general population and included both people with some steppe ancestry and others, like the Griffin Warrior, without it. Similarly, people in the central area of the Urartian Kingdom around Lake Van lacked the steppe ancestry characteristic of the kingdom's northern provinces. Anatolia exhibited extraordinary continuity down to the Roman and Byzantine periods, with its people serving as the demographic core of much of the Roman Empire, including the city of Rome itself. During medieval times, migrations associated with Slavic and Turkic speakers profoundly affected the region

Ancient DNA from Mesopotamia suggests distinct Pre-Pottery and Pottery Neolithic migrations into Anatolia

We present the first ancient DNA data from the Pre-Pottery Neolithic of Mesopotamia (Southeastern Turkey and Northern Iraq), Cyprus, and the Northwestern Zagros, along with the first data from Neolithic Armenia. We show that these and neighboring populations were formed through admixture of pre-Neolithic sources related to Anatolian, Caucasus, and Levantine hunter-gatherers, forming a Neolithic continuum of ancestry mirroring the geography of West Asia. By analyzing Pre-Pottery and Pottery Neolithic populations of Anatolia, we show that the former were derived from admixture between Mesopotamian-related and local Epipaleolithic-related sources, but the latter experienced additional Levantine-related gene flow, thus documenting at least two pulses of migration from the Fertile Crescent heartland to the early farmers of Anatolia
