Gambia: Coastal Threads of Today

The samples assigned to "Modern Gambia" capture life at a single temporal snapshot: the year 2000 CE. Archaeological continuity along the Gambian coast — seen in settlement traces, fishing infrastructure, and trade-linked artefacts — creates a long visual of human occupation, but modern collections reflect living communities rather than deep-time layers.

Archaeological data indicates persistent coastal economies shaped by estuarine resources of the Gambia River and Atlantic littoral. Landscapes of mangrove, tidal flats and riverine floodplains have long directed settlement, mobility and material culture. Ethnohistoric records and excavations elsewhere in Senegambia show how trade, seasonal fishing, and small-scale agriculture form a resilient fabric that frames modern lifeways.

Genetically, this snapshot sits atop millennia of movement across West Africa. Limited evidence in this dataset (haplogroups not listed) prevents direct claims about specific lineages in these 113 samples, but comparative regional studies point toward deeply rooted West African ancestries that reflect both local continuity and historical interactions.

This dataset comprises 113 samples from the Western District and Western Divisions dated to 2000 CE. The submission does not list specific Y‑DNA or mtDNA haplogroups, so direct claims about lineage proportions within these samples cannot be asserted. Where the dataset is silent, comparative population genetics for Gambian and broader Senegambian populations provide a cautious interpretive frame.

Regionally, living Gambian populations typically show Y‑chromosome profiles with high frequencies of haplogroup E1b1a (E‑M2) and mitochondrial DNA dominated by sublineages of macro-haplogroup L (L0, L1, L2, L3). Genome-wide studies of West African populations reveal deep autochthonous ancestry components, layered with signals of historical contact across the Sahel and Atlantic coast.

Important caveats: because haplogroup details are not provided for these 113 samples, any direct mapping of lineages to archaeological features is preliminary. The sample count, however, is substantial enough to support population-level analyses if accompanying genetic calls are later released. Spatially concentrated sampling (Western District/Divisions) means findings primarily reflect coastal Gambian diversity and may not capture inland variation.
