Overview
J1-FGC10812 is a downstream branch of the highland-anchored J1-Z1828 lineage and originated among agro-pastoral populations inhabiting the Armenian Highlands, eastern Anatolia and the northern Zagros. These communities developed upland farming systems, practiced vertical transhumance and participated in early metallurgical traditions associated with highland West Asian cultures. Archaeological patterns strongly correlate this lineage with cultural horizons branching from or interacting with the Kura-Araxes world. Throughout the Bronze and Iron Ages, FGC10812-bearing groups remained ecologically and geographically isolated in mountainous regions. This isolation resulted in tightly clustered downstream microclades. Medieval highland populations from Armenia and eastern Anatolia show strong continuity with ancestral FGC10812 lineages, reflecting long-term demographic stability across millennia.
