Overview
J1-ZS351 is a downstream lineage under J1-L147.1, the major structural backbone of the Arabian centered P58 radiation. Its early development took place during the late Neolithic and early Chalcolithic expansions of pastoral groups across the Arabian plateau. Climatic fluctuations, including shifts in aridity, likely influenced the early movements of ZS351 ancestral populations. By the Bronze and Iron Ages, ZS351 bearing groups were part of the emerging tribal confederations of north and central Arabia, interacting with the Levant through trade corridors, pastoral mobility and early political alliances. The clade shows layered microstructure reflecting multiple tribal founder effects. Some of its downstream branches appear to correlate geographically with historically documented Arabian tribal groupings, though the lineage itself is older than recorded genealogical traditions.
