Overview
G-Y251884 is a mountain-basin lineage shaped by Bronze Age interactions between eastern Anatolia, the Armenian Highlands and northern Mesopotamia. The lineage likely arose from settled agro-pastoral communities thriving along river valleys and elevated plains that bridged highland and lowland ecotones. Its demographic history reflects the cultural complexity of Hurrian, Urartian and early Assyrian interactions.
The branch shows deep continuity in rugged terrain, where paternal lines persisted through extended periods of political turnover. It represents a highland continuity lineage rather than a migratory expansion lineage, making it essential for reconstructing localized demographic histories.
Geographic distribution
Modern carriers are most frequently found in Armenia, eastern Turkey, northern Iraq and northwest Iran. Occasional individuals appear in Georgia. The lineage is nearly absent elsewhere, underlining its highland-focused demographic trajectory.
Ancient DNA
- Bronze Age individuals from the Lake Van region show upstream markers resembling early Y251884.
- Iron Age highland settlements demonstrate autosomal and upstream paternal affinities aligned with this lineage’s core structure.
- Urartian cultural horizon individuals provide contextual support for long-term continuity.
Phylogeny & subclades
Y251884 forms a small but structured branch, with two major clades: a Lake Van-Armenian plateau clade and a northern Mesopotamian clade. Divergence times cluster around the late Bronze Age, matching archaeological settlement patterns.
- G-Y251884* Armenian plateau basal line
- G-Y251884a Lake Van region clade
- G-Y251884b northern Mesopotamian branch
- rare Zagros foothill microlineages
Notes & context
This lineage strengthens the atlas’s highland continuity component and provides important representation of the eastern Anatolia–Mesopotamia interface.
