Overview
J1-Y6102 is a downstream branch of the core Arabian J1-P58 radiation that likely formed among pastoralist groups inhabiting northern Arabia and the transitional zones between the Hejaz and southern Jordan during the early Bronze Age. These communities utilized desert wells, seasonal wadis and predictable grazing zones, forming mobility circuits that later became demographic anchors for early North Arabian tribal cultures. Archaeological parallels to ancestral Y6102 populations include desert encampments near caravan staging points and oasis-linked exchange networks. During the Bronze and Iron Ages, Y6102-bearing groups participated in expansions across the Hejaz and Wadi Sirhan corridor. Founder effects shaping the downstream phylogeny reflect well-defined clan structures that persisted into the early Islamic era, when some branches expanded eastward into Iraq and Kuwait.
