Eleuthera Taino Echoes

The individual from Preacher's Cave on Eleuthera dates to the Late Ceramic period in the northern Caribbean (radiocarbon-calibrated range 892–1022 CE). Archaeological data indicate that the people archaeologists label as Taino in the Greater Antilles and adjacent island groups are the product of long-distance movements of Arawakan-speaking, ceramic-producing populations that dispersed northward from northern South America over the first millennium BCE and into the first millennium CE. Material culture — including distinct pottery styles, ground stone tools, and settlement forms — shows affinities across the northern Lesser Antilles, the Greater Antilles, and the Bahamian archipelago.

Preacher's Cave has yielded cultural deposits that situate Eleuthera within these networks of exchange and mobility. The single genetic sample from this site provides a direct biological link to that archaeological horizon, but that link must be framed carefully: one mtDNA result can confirm presence of a lineage (here, haplogroup B2) but cannot by itself reconstruct migration routes, population size, or the full diversity of Bahamian peoples. Limited evidence suggests continuity with broader Arawakan ancestries, yet archaeological and genetic work across more Bahamian sites is needed to turn suggestive patterns into robust models.

The genetic evidence from Preacher's Cave is currently limited to a single mitochondrial genome assigned to haplogroup B2. Haplogroup B2 is one of the well-established Native American maternal lineages with deep roots tracing back to the initial peopling of the Americas via Beringia and subsequent southward dispersals. Its presence in a Late-1st-millennium CE Bahamian individual is consistent with broader patterns of Indigenous American maternal diversity observed across the Caribbean and mainland Americas.

Important constraints shape interpretation. With only one sampled individual from Eleuthera (sample count = 1), any population-level inference is preliminary. The absence of recovered Y-chromosome data for this individual means paternal lineages remain unknown. Archaeogenetic studies from other Caribbean islands often show a mixture of Arawakan-associated ancestries and local insular variation; therefore, the Preacher's Cave B2 result signals continuity with Indigenous American maternal lineages but cannot alone define migration timing, admixture events, or the presence of other maternal haplogroups in the Bahamian population.

Future sampling across multiple Bahamian sites, incorporation of nuclear genome data, and direct comparison with contemporaneous Greater Antillean and South American ancient genomes will be required to move from suggestive connections to detailed reconstructions of ancestry, kinship, and population dynamics.
