    Ancient DNA from Mesopotamia suggests distinct Pre-Pottery and Pottery Neolithic migrations into Anatolia
    (Amer Assoc Advancement Science, 2022) Lazaridis, Iosif; Alpaslan-Roodenberg, Songül; Acar, Ayşe; Açıkkol, Ayşen; Agelarakis, Anagnostis; Aghikyan, Levon; Akyüz, Uğur
    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.

    The genetic history of the Southern Arc: A bridge between West Asia and Europe
    (Amer Assoc Advancement Science, 2022) Lazaridis, Iosif; Alpaslan-Roodenberg, Songül; Acar, Ayşe; Açıkkol, Ayşen; Davtyan, Ruben; Agelarakis, Anagnostis; Aghikyan, Levon
    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 IndoAnatolian language family was in West Asia, with only secondary dispersals of non-Anatolian IndoEuropeans from the steppe.

    A genetic probe into the ancient and medieval history of Southern Europe and West Asia
    (Amer Assoc Advancement Science, 2022) Lazaridis, Iosif; Alpaslan-Roodenberg, Songül; Acar, Ayşe; Açıkkol, Ayşen; Agelarakis, Anagnostis; Aghikyan, Levon; Akyüz, Uğur
    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.
