Overview
J2a-Y16783 is an upland-centered lineage under the J2a-M67 macro-branch and is linked to populations settled in the high-altitude regions of the Armenian plateau, eastern Anatolia and the fringes of northern Mesopotamia. Its early formation corresponds to the consolidation of mixed agriculture and herding communities occupying highland valleys and mountain basins during the early Holocene.
Bronze Age cultural landscapes saw Y16783 anchored in regions tied to Upper Tigris fortified settlements, highland metallurgical zones and the early iterations of mountain corridor trade. The lineage's downstream structure reveals restricted dispersal and microregional founder effects associated with isolated upland communities. Its continuity into the Iron Age and classical periods demonstrates the lineage's strong anchoring in culturally conservative highland populations.
Geographic distribution
Armenia, eastern Turkey, northwest Iran, northern Iraq; minor frequencies in Georgia and northern Syria.
Ancient DNA
- Bronze Age Armenian plateau burials display upstream variation consistent with Y16783 ancestry.
- Chalcolithic Upper Tigris samples show J2a-M67 diversity linked to the lineage.
- Eastern Anatolian Bronze Age sites contain paternal markers aligned with the ancestral structure of the clade.
- Iron Age upland communities exhibit downstream derivatives.
- Classical highland populations preserve continuity with Y16783 microbranches.

Notes & context
Y16783 is essential for reconstructing persistent highland settlement continuity from the Chalcolithic onward.
