Overview
J1-Y6247 is a downstream derivative of the core Arabian J1-P58 radiation and likely originated among pastoralist populations living across central and northern Arabia during the early Bronze Age. These early groups practiced a mobile pastoral economy anchored to wells, oasis clusters and seasonal wadis, which defined predictable cycles of movement through desert-steppe ecologies. Archaeological settings associated with these societies include multi-season encampments, small fortified installations near water sources and caravan-linked trade infrastructure. During the Bronze and Iron Ages, Y6247-bearing communities participated in demographic expansions that shaped the tribal landscape of the Hejaz, Najd and the southern Levant. The downstream phylogeny indicates several localized founder events tied to stable clan structures. Early Islamic period expansions dispersed some descendants into Iraq, Kuwait and parts of the Gulf region, where further microbranching occurred.
