Overview
J1-Z1853 is a downstream branch of J1-Z1828 that is particularly enriched in populations of the southern and central Caucasus and the adjacent eastern Anatolian highlands. Its formation timeframe suggests that it emerged in Holocene highland communities that had already adopted agro-pastoral subsistence strategies and were integrated into expanding regional interaction networks. By the Bronze Age, Z1853-bearing groups were likely involved in the complex mosaic of chiefdoms and early polities across the Armenian highlands, parts of Georgia and northeastern Anatolia, linking highland livestock production with lowland urban centers through caravan trade routes. The clade’s distribution and diversity indicate that it was shaped by repeated episodes of demographic expansion, local isolation and clan- or tribe-level structuring.
Geographic distribution
Modern J1-Z1853 frequencies are highest in Armenia, Georgia, eastern Turkey and parts of northern Iran and northern Iraq. Substantial representation is seen among some Armenian, Georgian and Kurdish populations, as well as select North Caucasian groups. Lower frequencies appear in the Levant and the wider Middle East, often tracing back to historical relocations or diasporic movements from the Caucasus or eastern Anatolia. In diaspora settings, Z1853 frequently marks paternal lineages of families with documented Caucasus or Armenian highland origins.
Ancient DNA
- Bronze Age individuals from the Armenian highlands show J1 lineages consistent with early Z1853 diversification.
- Kura–Araxes archaeological contexts in Armenia and eastern Anatolia include J1 profiles that sit phylogenetically near or within Z1853.
- Iron Age samples from Urartian cultural sites suggest continuity of highland J1 lineages compatible with Z1853-bearing populations.
- Late Bronze and Iron Age individuals in northern Mesopotamia show occasional J1 lineages that likely derive from highland Z1853 expansions.
- Medieval cemetery samples in the Caucasus preserve J1 substructure matching modern Z1853 distributions.
Phylogeny & subclades
J1-Z1853 forms a compact but internally stratified set of lineages under Z1828, with multiple microclades exhibiting strong geographic clustering in specific valleys, plateaus and mountain regions of the Caucasus and eastern Anatolia. These patterns reflect long-term residence in rugged terrain, limited gene flow in some locales and the impact of social structures such as clan- and village-based endogamy.

- Caucasian microclades in Armenia and Georgia
- Eastern Anatolian branches with partial spread into northern Mesopotamia
- Rare Levantine and Iranian Plateau subbranches
Notes & context
J1-Z1853 is especially useful for fine-scale studies of Caucasus and Armenian highland paternal structure, capturing the imprint of long-term settlement in mountainous ecologies. Its detailed substructure has the potential to correlate with specific historical processes such as the consolidation of highland polities, but should always be interpreted in light of complex admixture and population movements in the region.
