    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.

    Entwined African and Asian Genetic Roots of Medieval Peoples of the Swahili Coast

    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.
