Overview
J1-ZS3752 is a downstream lineage under the Arabian-centered J1-L147.1 clade and is associated with pastoralist populations of northern Arabia, the Jordanian steppe and the Syro-Arabian desert margins. Its formation coincides with mid Holocene patterns of desert pastoral mobility, where seasonal grazing circuits and oasis-linked subsistence strategies developed across northern Arabian ecologies.
During the Bronze and Iron Ages, ZS3752-bearing groups were integrated into tribal populations inhabiting desert margins, caravan pathways and upland-desert transitional zones. Some downstream clades may have entered early Arab tribal structures, while ancestral layers represent pre-Arab desert communities adapted to arid and semi-arid settings. Classical and early medieval desert settlements retained the lineage among pastoralist groups with long-term continuity.
Geographic distribution
Northern Arabia, Jordan, southern Syria, Iraq; rare occurrences in the Hijaz and the Levant interior.
Ancient DNA
- Chalcolithic Levantine samples contain upstream J1 components compatible with the basal ancestry of ZS3752.
- Bronze Age northern Arabian individuals exhibit markers aligned with the lineage’s deeper structure.
- Iron Age Syrian desert burials show downstream elements belonging to this branch.
- Classical oasis settlements appear to preserve microbranch continuity.
- Early Arab expansions may have dispersed later derivatives across northern Arabia and Mesopotamia.
Phylogeny & subclades

Notes & context
ZS3752 is useful for reconstructing early pastoral mobility systems and long-term desert settlement continuity.
