Dietary 14C reservoir effects and the chronology of prehistoric burials at Sakhtysh, central European Russia

We present the first robust radiocarbon (14C) chronology for prehistoric burial activity at Sakhtysh, in European Russia, where nearly 180 inhumations attributed to Lyalovo and Volosovo pottery-using hunter-gatherer-fishers represent the largest known mortuary populations of these groups. Past attempts at 14C dating were restricted by poor preservation and limited understanding of diet and dietary 14C reservoir effects (DREs). We obtained 32 new AMS (Accelerator Mass Spectrometry) 14C dates on human petrous bones. Dietary stable isotopes ({delta}13C, {delta}15N) for all AMS-dated human samples allow us to propose a novel DRE correction model, using differences in 14C, {delta}13C and {delta}15N from bones and teeth of the same individuals to predict DREs of up to c.900 14C years. Our chronological model for 40 individuals dates Lyalovo burials to the early 5th millennium cal BC, and Volosovo burials to the mid-4th to early 3rd millennium. It reveals a previously unrecognised shift in the Volosovo subsistence economy at c.3300 cal BC, coinciding with a reorientation of trade networks, and shows that the last burial at Sakhtysh was the only one in a crouched position, which coincided with the beginning of Fatyanovo practices, the regional expression of the Yamnaya/Corded Ware expansion.

The population history of northeastern Siberia since the Pleistocene

Far northeastern Siberia has been occupied by humans for more than 40 thousand years. Yet, owing to a scarcity of early archaeological sites and human remains, its population history and relationship to ancient and modern populations across Eurasia and the Americas are poorly understood. Here, we analyze 34 ancient genome sequences, including two from fragmented milk teeth found at the ~31.6 thousand-year-old (kya) Yana RHS site, the earliest and northernmost Pleistocene human remains found. These genomes reveal complex patterns of past population admixture and replacement events throughout northeastern Siberia, with evidence for at least three large-scale human migrations into the region. The first inhabitants, a previously unknown population of \"Ancient North Siberians\" (ANS), represented by Yana RHS, diverged ~38 kya from Western Eurasians, soon after the latter split from East Asians. Between 20 and 11 kya, the ANS population was largely replaced by peoples with ancestry related to present-day East Asians, giving rise to ancestral Native Americans and \"Ancient Paleosiberians\" (AP), represented by a 9.8 kya skeleton from Kolyma River. AP are closely related to the Siberian ancestors of Native Americans, and ancestral to contemporary communities such as Koryaks and Itelmen. Paleoclimatic modelling shows evidence for a refuge during the last glacial maximum (LGM) in southeastern Beringia, suggesting Beringia as a possible location for the admixture forming both ancestral Native Americans and AP. Between 11 and 4 kya, AP were in turn largely replaced by another group of peoples with ancestry from East Asia, the \"Neosiberians\" from which many contemporary Siberians derive. We detect gene flow events in both directions across the Bering Strait during this time, influencing the genetic composition of Inuit, as well as Na Dene-speaking Northern Native Americans, whose Siberian-related ancestry components is closely related to AP. Our analyses reveal that the population history of northeastern Siberia was highly dynamic throughout the Late Pleistocene and Holocene. The pattern observed in northeastern Siberia, with earlier, once widespread populations being replaced by distinct peoples, seems to have taken place across northern Eurasia, as far west as Scandinavia.

Paleo-Eskimo genetic legacy across North America

Paleo-Eskimos were the first people to settle vast regions of the American Arctic around 5,000 years ago, and were subsequently joined and largely displaced around 1,000 years ago by ancestors of the present-day Inuit and Yupik. The genetic relationship between Paleo-Eskimos and Native American populations remains uncertain. We analyze ancient and present-day genome-wide data from the Americas and Siberia, including new data from Alaskan Inupiat and West Siberian populations, and the first genome-wide DNA from ancient Aleutian Islanders, ancient northern Athabaskans, and a 4,250-year-old individual of the Chukotkan Ust'-Belaya culture. Employing new methods based on rare allele and haplotype sharing as well as established methods based on allele frequency correlations, we show that Paleo-Eskimo ancestry is widespread among populations who speak Na-Dene and Eskimo-Aleut languages. Using phylogenetic modelling with allele frequency correlations and rare variation, we present a comprehensive model for the complex peopling of North America.
