Overview
J1-Y5982 is a downstream component of the major Arabian J1-P58 expansion and appears to have originated among pastoralist communities situated across the central and northern Arabian Peninsula during the early Bronze Age. These groups relied heavily on short-range seasonal mobility involving wells, ephemeral streams and stable grazing zones near oasis corridors, forming a demographic core that later fed into the formation of early North Arabian tribal societies. Throughout the Bronze and Iron Ages, populations bearing Y5982 became involved in the demographic expansions shaping the Hejaz, northern Arabia and adjoining areas of southern Jordan. Downstream structure indicates multiple founder effects linked with early clan-based tribal formations. During the early Islamic period, several derivative subbranches of Y5982 expanded into Iraq and parts of the Gulf region, where additional localized microclades emerged.
