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.

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.

In 2016, archaeological excavations undertaken by the Ephorate of Antiquities of West Attica, Piraeus and Islands 3.8 km south-west of Athens, Greece, revealed mass burials of 79 skeletons in three rows. The burials are dated to the 7th century BC. The anthropological field documentation was undertaken by The Swedish Institute of Athens, and followed established bioarchaeological protocols regarding taphonomic processes, age, sex, injuries, and pathological changes. The descriptions and interpretations should be regarded as preliminary field observations. A majority of the individuals were young adult or juvenile males, most of them without signs of active disease and with a generally good oral health status, but with corroded iron shackles around their wrists. Cause of death could not be determined although extensive and likely perimortem fractures were observed. The only object related to injury and/or possible cause of death was an arrowhead found in the chest of one of the skeletons. Why and where the individuals were killed is a matter of conjecture; the observations from the field documentation neither validate, nor disprove the hypothesis that these individuals were captives and victims of the so-called “Cylonian conspiracy” in the 7th century BC.

Le poste routier du lieu-dit Παράγκα, à Χοιρόμανδρες, est l'un des postes de garde les plus importants de la route reliant l'habitat minoen d'Aμπέλoς (Ξηρόκαμπος) à la région fortement peuplée de Πάνω Ζάκρος et à la ville palatiale du même nom. La dernière campagne de fouille de la construction, dans le courant de l'année 1989, et les études topographiques complémentaires effectuées dans la vallée de Χοιρόμανδρες, ont confirmé qu'il s'agit d'une puissante construction à caractère défensif, s'insérant dans un programme plus vaste, destiné à contrôler les communications. Il fut fondé au MM II et resta en usage jusqu'au MR IB, époque à laquelle il s'écroula, mais il est impossible de préciser si son utilisation a changé lors des occupations successives. L'aménagement architectural et les trouvailles ont des parallèles, aussi bien dans d'autres postes de garde routiers que dans des édifices datant du Minoen Moyen, l'époque où devrait avoir été dessiné le réseau routier minoen.
