    Humans settled the Caribbean ~6,000 years ago, with ceramic use and intensified agriculture marking a shift from the Archaic to the Ceramic Age ~2,500 years ago. We report genome-wide data from 174 individuals from The Bahamas, Hispaniola, Puerto Rico, Curaçao, and Venezuela co-analyzed with published data. Archaic Age Caribbean people derive from a deeply divergent population closest to Central and northern South Americans; contrary to previous work, we find no support for ancestry contributed by a population related to North Americans. Archaic lineages were >98% replaced by a genetically homogeneous ceramic-using population related to Arawak-speakers from northeast South America who moved through the Lesser Antilles and into the Greater Antilles at least 1,700 years ago, introducing ancestry that is still present. Ancient Caribbean people avoided close kin unions despite limited mate pools reflecting small effective population sizes which we estimate to be a minimum of Ne=500-1500 and a maximum of Ne=1530-8150 on the combined islands of Puerto Rico and Hispaniola in the dozens of generations before the analyzed individuals lived. Census sizes are unlikely to be more than ten-fold larger than effective population sizes, so previous estimates of hundreds of thousands of people are too large. Confirming a small, interconnected Ceramic Age population, we detect 19 pairs of cross-island cousins, close relatives ~75 kilometers apart in Hispaniola, and low genetic differentiation across islands. Genetic continuity across transitions in pottery styles reveals that cultural changes during the Ceramic Age were not driven by migration of genetically-differentiated groups from the mainland but instead reflected interactions within an interconnected Caribbean world.

    The Yamnaya archaeological complex appeared around 3300 BCE across the steppes north of the Black and Caspian Seas, and by 3000 BCE reached its maximal extent from Hungary in the west to Kazakhstan in the east. To localize Yamnaya origins among preceding Eneolithic people, we assembled ancient DNA from 428 individuals, demonstrating three genetic clines. A “Caucasus-Lower Volga” (CLV) Cline suffused with Caucasus hunter-gatherer1 ancestry extended between a Caucasus Neolithic southern end, and a northern end at Berezhnovka along the Lower Volga river. Bidirectional gene flow created intermediate populations, such as north Caucasus Maikop people, and those at Remontnoye on the steppe. The “Volga Cline” was formed as CLV people mixed with upriver populations of Eastern hunter-gatherer2 ancestry, creating hyper-variable groups as at Khvalynsk. The “Dnipro Cline” was formed as CLV people moved west, mixing with Ukraine Neolithic hunter-gatherers3 along the Dnipro river to establish Serednii Stih groups from whom Yamnaya ancestors formed around 4000 BCE and grew explosively after 3750-3350 BCE. CLV people contributed four-fifths of the ancestry of the Yamnaya, and, entering Anatolia likely from the east, at least a tenth of the ancestry of Bronze Age Central Anatolians, where Hittite was spoken4,5. We thus propose that the final unity of the speakers of “Proto-Indo-Anatolian”, the language ancestral to both Anatolian and Indo-European, was among CLV people sometime between 4400-4000 BCE.

    A genomic history of the North Pontic Region from the Neolithic to the Bronze Age

    The north Black Sea (Pontic) Region was the nexus of the farmers of Old Europe and the foragers and pastoralists of the Eurasian steppe1,2, and the source of waves of migrants that expanded deep into Europe3–5. We report genome-wide data from 78 prehistoric North Pontic individuals to understand the genetic makeup of the people involved in these migrations and discover the reasons for their success. First, we show that native North Pontic foragers had ancestry not only from Balkan and Eastern hunter-gatherers6but also from European farmers and, occasionally, Caucasus hunter-gatherers. More dramatic inflows ensued during the Eneolithic, when migrants from the Caucasus-Lower Volga area7moved westward, bypassing the local foragers to mix with Trypillian farmers advancing eastward. People of the Usatove archaeological group in the Northwest Pontic were formed ca. 4500 BCE with an equal measure of ancestry from the two expanding groups. A different Caucasus-Lower Volga group, moving westward in a distinct but temporally overlapping wave, avoided the farmers altogether, and blended with the foragers instead to form the people of the Serednii Stih archaeological complex7. A third wave of expansion occurred when Yamna descendants of the Serednii Stih forming ca. 4000 BCE expanded during the Early Bronze Age (3300 BCE). The temporal gap between Serednii Stih and the Yamna expansion is bridged by a genetically Yamna individual from Mykhailivka in Ukraine (3635-3383 BCE), a site of uninterrupted archaeological continuity across the Eneolithic-Bronze Age transition, and the likely epicenter of Yamna formation. Each of these three waves propagated distinctive ancestries while also incorporating outsiders during its advance, a flexible strategy forged in the North Pontic region that may explain its peoples’ outsized success in spreading their genes and culture across Eurasia3–5,8–10.

    Entwined African and Asian Genetic Roots of Medieval Peoples of the Swahili Coast
    (SpringerNature, 2023-03-29) Brielle, Esther; Fleisher, Jeffrey; Wynne-Jones, Stephanie; Sirak, Kendra; Broomandkhoshbacht, Nasreen; Callan, Kimberly; Curtis, Elizabeth; Iliev, Lora; Lawson, Ann; Oppenheimer, Jonas; Qiu, Lijun; Stewardson, Kristin; Workman, James; Zalzala, Fatma; Ayodo, George; Gidna, Agness; Kabiru, Angela; Kwekason, Amandus; Mabulla, Audax Z.

    The urban peoples of the Swahili coast traded across eastern Africa and the Indian Ocean and were among the first sub-Saharan practitioners of Islam [1, 2]. The extent to which these early interactions between Africans and non-Africans were accompanied by genetic exchange remains unknown. We report ancient DNA data for 80 individuals from six medieval and early modern (1250-1800 CE) coastal towns and an inland town postdating 1650 CE. Many coastal individuals had over half their DNA from primarily female African ancestors, with large proportions and occasionally more than half from Asian ancestors. The Asian ancestry included both Persian and Indian-associated components, with eighty to ninety percent from Persian males. Peoples of African and Asian origins began to mix by about 1000 CE, coinciding with large-scale adoption of Islam. Before about 1500 CE, the Southwest Asian ancestry was mainly Persian-related, consistent with the narrative of the Kilwa Chronicle, the oldest history told by people of the Swahili coast [3]. After this time, the sources became increasingly Arabian, consistent with evidence of growing interactions with southern Arabia [4]. Subsequent interactions with Asians and Africans further changed the ancestry of Swahili coast people relative to the medieval individuals whose DNA we sequenced.

    Present-day people from England and Wales harbour more ancestry derived from Early European Farmers (EEF) than people of the Early Bronze Age1. To understand this, we generated genome-wide data from 793 individuals, increasing data from the Middle to Late Bronze and Iron Age in Britain by 12-fold, and Western and Central Europe by 3.5-fold. Between 1000-875 BCE, EEF ancestry increased in southern Britain (England and Wales) but not northern Britain (Scotland) due to incorporation of migrants who arrived at this time and over previous centuries, and who were genetically most similar to ancient individuals from France. These migrants contributed about half the ancestry of Iron Age people of England and Wales, thereby creating a plausible vector for the spread of early Celtic languages into Britain. These patterns are part of a broader trend of EEF ancestry becoming more similar across Central and Western Europe in the Middle to Late Bronze Age, coincident with archaeological evidence of intensified cultural exchange2-6. There was comparatively less gene flow from continental Europe during the Iron Age, and Britain’s independent genetic trajectory is also reflected in the rise of the allele conferring lactase persistence to ~50% by this time compared to ~7% in Central Europe where it rose rapidly in frequency only a millennium later. This suggests that dairy products were used in qualitatively different ways in Britain and in Central Europe over this period.
