Overview
G-Y182347 represents a cluster whose early development occurred in the eastern Anatolia to southern Caucasus corridor. This region was a major interaction zone during the Bronze Age, where populations associated with Hurrian, Urartian and other highland cultural traditions contributed to a complex demographic mosaic. G-Y182347 appears to have emerged in communities deeply integrated into these highland ecosystems.
The lineage is notable for maintaining localized continuity in mountainous environments where population density was lower but long term genealogical preservation was more stable. Such contexts often preserve older paternal lines that elsewhere became overshadowed by demographic expansions.
Geographic distribution
G-Y182347 today is concentrated in Armenia, eastern Turkey, northern Iraq and parts of Georgia. It also occurs sporadically in Iran. The modern distribution fits a pattern of Bronze Age continuity in highland settlements that experienced fewer large scale demographic turnovers compared to lowland regions.
Ancient DNA
- Middle Bronze Age individuals from the Lake Van region show upstream SNP patterns consistent with proto Y182347 ancestry.
- Urartian period samples from eastern Anatolia occasionally present haplotypes that align with basal Y182347 configurations.
- No confirmed European ancient DNA belongs to this branch, which supports a strictly Near Eastern development path.
Phylogeny & subclades
Within G2a2b1a, Y182347 sits as a sibling lineage to FT41950 and FT49621 but retains a more geographically restricted structure. It forms a few internal branches that show tight clustering in the Caucasus highlands. Phylogenetically it represents an older retention line inside the broader M406 radiation, conserving signals of early Bronze Age population structure.
- G-Y182347* basal Armenian and Lake Van cluster
- G-Y182347a northern Iraq derived branch
- G-Y182347b southern Caucasus microclade
- minor Iranian foothill lineages
Notes & context
G-Y182347 contributes to the atlas by representing highland Near Eastern paternal continuity from the Bronze Age to the present. Its preservation in mountain environments highlights the role of isolated populations in maintaining rare haplogroup structures.
