Overview
J1-Y3836 is a downstream Arabian-rooted lineage within the J1-P58 radiation, emerging during the late Neolithic and early Bronze Age phases of pastoral intensification in northern Arabia. Its ancestral communities likely practiced a mixed pastoral economy centered on herd mobility, seasonal grazing regions and strategic exploitation of oases along the Syro-Arabian steppe. Archaeological correlates include desert pastoral camps, early caravan trails and copper-age waystations in the northern Hejaz and southern Jordan. Through the Bronze and Iron Ages, Y3836-bearing populations appear to have integrated into the wider network of North Arabian and southern Levantine tribal structures. Their spatial distribution and internal phylogenetic segmentation suggest widespread involvement in tribal-level demographic pulses connected with the early historic incense trade and the rise of proto-Arabic-speaking confederations. The microbranching within Y3836 indicates discrete founder effects tied to tribal and clan-based identities.
