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.
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.
During archaeological rescue excavations carried out in 2007 at Potočani in continental Croatia, a pit containing numerous human skeletal remains (MNI = 41) was discovered. The remains were mostly articulated but also commingled and showed no clear pattern of organization. There were no associated artifacts, just a few pottery fragments probably belonging to the Copper Age Lasinja Culture (c. 4300 to 3950 BCE). Anthropological analyses suggest the presence of individuals of all ages and both sexes with many crania exhibiting various perimortem injuries. Three human bone samples from different layers were dated to around 4100 cal BCE by radiocarbon analysis. These radiocarbon dates combined with other aspects of archaeological context, indicate that the deposition was a single episode rather than a long-term accumulation. All this suggests a single violent encounter (massacre). Here we present results of the bioarchaeological analysis of four adult crania with clear signs of perimortem trauma. These include blunt force trauma as well as cuts and penetrating injuries indicating the use of different weapons/tools.
Diet often plays a vital role in defining social divisions within and between social groups and thus can be used to understand the social paradigms of archeological cultures. During the Early Avar period (568-630 A.D.), burial evidence indicates that there were strong demarcations of social stratification and divisions between sexes and age groups; however, the symbols of intrapopulation heterogeneity become increasingly rare during the Late Avar period (680-822 A.D.). In this study, we investigate social differences expressed through diet in the cemetery population from Nuštar, eastern Croatia (eighth to early ninth century), to determine whether dietary social disparities existed during the Late Avar period in this region. Stable isotope analysis of carbon (δ 13 C) and nitrogen (δ 15 N) from bone and dentine collagen shows no dietary differences, neither between high, middle, and low status individuals, nor between males, females, and juveniles. These results likely reflect the outcome of the social homogenization process that began after the failed Avar attack on Constantinople in 626 A.D. Geographical patterning is visible when the data from Nuštar is compared to data from other Middle and Late Avar sites. While Avar sites in the southern and south-eastern frontiers of the Avar qaganate do not display dietary differences between sexes, previous isotopic work on populations in Lower Austria shows that males consumed a higher proportion of animal protein than females. This is likely the result of Frankish influence and reflects diversity in social practices within the Avar qaganate itself during the Middle and Late Avar periods.
