Overview
J1-ZS462 is a downstream branch of the widespread J1-L147.1 lineage, itself a major component of the Arabian-centered J1-P58 expansion. The clade emerged during the late Neolithic to early Bronze Age when expanding pastoral networks began linking the northern Arabian plateau with southern Mesopotamia and the southern Levant. Environmental pressures and the development of oasis-based subsistence strategies likely shaped the early demographic behaviors of the lineage. During the Bronze and Iron Ages, ZS462-bearing groups participated in the formation of North Arabian tribal confederations, trade routes and cultural networks associated with early Semitic expansions. Its downstream phylogeny suggests multiple localized founder events, with branches showing geographic coherence in the northern Arabian interior and adjoining Levantine regions.
