Overview
E-Z2336 is one of the most expansive and demographically influential branches of the E-Z1725 cluster, which lies at the core of paternal West and Central African population history. Emerging during the mid-to-late Holocene, E-Z2336 diversified in a biological and cultural landscape defined by rising agricultural innovation, intensifying settlement patterns and proto-urban developments across the Niger–Benue corridor and the Cameroon grassfields. Compared to narrower branches like E-Z1722, E-Z2336 exhibits a far broader geographic spread and a richer, more complex phylogenetic structure. Its lineage diversity mirrors some of the earliest demographic pulses that preceded and later intertwined with the Bantu expansions, embedding E-Z2336 deeply into the paternal ancestry of millions of people across sub-Saharan Africa.
Geographic distribution
Today, E-Z2336 is widely distributed across Nigeria, Cameroon, Gabon, Equatorial Guinea, the Democratic Republic of the Congo and surrounding regions. It is notably frequent among Bantoid speakers, many Niger–Congo populations of southern Nigeria and tribes occupying the Cross River, Lower Niger and northwestern Congo Basin territories. Some of its downstream clades appear at high frequencies among Bantu-speaking groups further south and east, illustrating that portions of E-Z2336 were incorporated early into dispersals that expanded into Central, Southern and Eastern Africa. In African diaspora populations, E-Z2336 is one of the more regularly encountered E-U175 derivatives, reflecting its strong representation in historically affected regions of the Gulf of Guinea.
Ancient DNA
- Although ancient DNA from West and Central Africa remains sparse due to climate limitations, temporal estimates position E-Z2336 diversification in the period when sedentary village clusters and early food-production systems were developing across the Niger–Benue–Cross River region.
- Linguistic and archaeological parallels suggest that several downstream branches of E-Z2336 belong to demographic networks that either fed into or interacted with the beginnings of the Bantu expansions.
- Internal TMRCA patterns imply multiple growth phases consistent with population consolidation during the late Holocene, ironworking diffusion and the establishment of major cultural spheres in West Central Africa.
Phylogeny & subclades
E-Z2336 contains numerous sub-branches, making it one of the densest components of the E-U175 phylogeny. Its structure reveals episodes of sustained local differentiation followed by later expansions that carried certain lineages across wide regions of Central and Southern Africa. Some subclades appear strongly associated with Nigeria–Cameroon upland populations, whereas others show signatures of movement into the Congo Basin, the Great Lakes region and beyond. The clustering of lineages within this branch suggests both ancient microregional continuity and subsequent long-distance dispersal, reflecting an intricate demographic history.

Notes & context
E-Z2336 stands out as one of the most informative paternal lineages for reconstructing the population structure of the Gulf of Guinea and the wider Bantu-influenced regions of Africa. Its widespread presence reflects both pre-Bantu demographic foundations and later incorporation into expanding cultural-linguistic spheres. The branch's internal complexity makes it highly valuable for fine-scale population genetics, historical linguistics and studies of regional continuity in West Central Africa.
