Overview
J1-FGC9275 is a highland-derived branch of the J1-Z1828 complex, originating among early agro-pastoral populations in the Armenian Highlands, eastern Anatolia and northern Zagros. These groups relied on mountain-based herding systems, highland irrigation networks and early metallurgical activity. Their cultural traditions contributed directly to the development of the Kura-Araxes horizon, which played a major role in spreading highland cultural innovations across West Asia. During the Bronze and Iron Ages, FGC9275-bearing communities remained concentrated within highland valleys and plateau regions where geographic isolation promoted long-term demographic stability. The lineage’s downstream structure is composed of highly localized microbranches that reflect clan-based continuity across multiple millennia. Archaeogenetic links show consistency between FGC9275-related populations and early highland settlements noted for fortification structures and transhumant pastoral networks.
