Overview
J1-Y5382 is a downstream offshoot of the Arabian-centered J1-P58 clade and formed among pastoralist populations inhabiting the northern Arabian plateau during the early Bronze Age. These groups practiced desert-steppe herding systems that relied on water sources such as wells and wadis, enabling short-range seasonal mobility. Their presence along trade-linked corridors between the Hejaz, southern Jordan and northern Arabia allowed them to take part in the region’s early caravan and oasis-based economic systems. During the Bronze and Iron Ages, Y5382-bearing groups contributed to tribal coalitions that shaped the North Arabian linguistic and demographic landscape. Its downstream phylogeny features founder-driven expansions tied to clan structures that developed in the Hejaz and northern Arabian regions. During the early Islamic era, several derivative lineages dispersed eastward into Iraq, Kuwait and parts of the Gulf.
