Overview
J1-ZS3336 is a downstream component of the J1-L147.1 Arabian-rooted expansion, associated with pastoralist communities distributed across northern Arabia, the Syrian desert margin and the Jordanian plateau. Its early emergence corresponds to mid Holocene climatic regimes that supported large-scale pastoral mobility, oasis-linked seasonal migrations and the development of desert frontier cultural networks.
Bronze and Iron Age demographic processes shaped the internal structure of ZS3336, with downstream clades spreading across northern Arabia and southern Syria. Some branches may have been absorbed into the earliest Arab tribal formations, while deeper layers reflect pre-Arab pastoral populations with long-term continuity across the desert margin corridor. Classical and later populations exhibit ongoing retention of derivative microbranches.
Geographic distribution
Northern Arabia, Jordan, southern Syria, Iraq; rare occurrences in the Levant and the Hijaz.
Ancient DNA
- Chalcolithic Levantine individuals show upstream J1 components consistent with ZS3336 ancestry.
- Bronze Age northern Arabia samples exhibit ancestral markers linked to this lineage.
- Iron Age Syrian interior burials reveal downstream clade structures.
- Classical desert belt populations preserve microbranch continuity.
- Early Arab tribal expansions likely carried derived subbranches.
