Overview
J1-FGC10485 is a downstream lineage of the highland-centered J1-Z1828 complex and emerged among early agro-pastoral groups occupying the Armenian Highlands, eastern Anatolia and the northern Zagros. These communities practiced vertical transhumance, maintained fortified upland settlements and participated in long-established metallurgical traditions characteristic of early West Asian highland societies. Their archaeological signatures align closely with phases of the Kura-Araxes cultural expansion. During the Bronze and Iron Ages, populations carrying FGC10485 remained geographically stable within mountainous zones where ecological boundaries preserved demographic continuity. The downstream topology reveals region-specific microclades formed by long-term settlement in highland valleys. Medieval populations of Armenia and eastern Anatolia show continued derivation from ancestral FGC10485 lineages, reflecting substantial continuity across millennia.
