Overview
J1-Y7288 is a downstream lineage of the Arabian-centered J1-P58 radiation and likely formed among pastoral groups occupying the northern Arabian Peninsula during the early Bronze Age. These ancestral communities practiced a desert-steppe pastoral lifestyle structured around reliable wells, limited-water wadis and oasis-linked grazing systems. Their settlement and mobility patterns reflect early tribal processes that later shaped North Arabian society. Throughout the Bronze and Iron Ages, Y7288-bearing groups moved across the Hejaz corridor, Wadi Sirhan and the transitional steppe regions of southern Jordan. The lineage's downstream topology shows several founder-driven events characteristic of clan-level social organization. With the expansion of the early Islamic world, Y7288 lineages spread into Iraq and eastern Arabia, where additional microclades formed through localized demographic growth.
