Turkey

Turkey's Anatolian peninsula preserves one of the longest records of human presence in western Eurasia. Archaeological evidence from caves such as Karain and Üçağızlı indicates that hominins, including early members of our species, occupied the region by at least 300,000–40,000 years ago, exploiting diverse coastal and inland environments during the Middle and Upper Paleolithic. These early occupations set the stage for repeated population movements, as Anatolia later served as a corridor for groups dispersing from the Levant and the Caucasus.

By the late Pleistocene and early Holocene, Anatolia witnessed the gradual transition from mobile foraging to settled communities. Sites such as Göbekli Tepe and the slightly later Aşıklı Höyük document monumental architecture and intensive plant management around 9600–8000 BCE, centuries before fully domesticated crops became widespread. Genetic and archaeobotanical data suggest that these developments occurred locally rather than through simple diffusion, although researchers continue to debate the relative contributions of indigenous foragers and incoming groups from the Fertile Crescent.

The subsequent Neolithic period saw Anatolia emerge as a primary source population for the farming expansion into Europe. Ancient DNA from individuals at Barcın, Tepecik-Çiftlik, and Çatalhöyük reveals a distinctive Anatolian-related ancestry that spread westward beginning around 7000 BCE, mixing only modestly with local hunter-gatherers in southeastern Europe. This genetic signal aligns with archaeological evidence of pottery, domestic animals, and architectural traditions that track the same route, underscoring Anatolia’s role in reshaping the demographic landscape of the continent.

Later prehistoric and historic periods brought successive waves of migration and cultural transformation. Bronze Age polities such as the Hittite Empire incorporated both local Anatolian lineages and newcomers from the Caucasus and northern Mesopotamia, while Iron Age movements associated with Phrygians, Greeks, and later Galatians introduced additional layers of ancestry. Ottoman-era population shifts further diversified the genetic and linguistic map, illustrating how Anatolia repeatedly absorbed and recombined influences from three continents.

Ongoing ancient-DNA studies continue to refine these narratives, revealing both long-term continuity in some highland communities and punctuated episodes of large-scale admixture. Because Anatolia lies at the intersection of multiple migration corridors, its archaeological and genetic records remain central to debates about the timing and drivers of major transitions in human prehistory, from the Neolithic demographic expansion to the spread of Indo-European languages.
