Ragged Island Ceramic — Flamingo Cay

Emerging between roughly 900 and 1500 CE, the Ragged Island Ceramic expression in the southern Bahamas is part of the broader Ceramic Age transformations that reshaped the Caribbean world. Archaeological data indicates pottery styles, shell-midden economies, and coastal camp sites that align this local variant with island-to-island networks across the southern Bahamas and into the Greater Antilles. Flamingo Cay, in the Ragged Island Range (Jumento Cays), provides the single ancient genomic anchor for this local ceramic tradition: a human bone sample associated with ceramic-bearing deposits dated within the 900–1500 CE range.

Material culture suggests people adapted to fragile island ecologies through specialized maritime subsistence and mobile settlement strategies. Ceramics provide stylistic signals of cultural affiliation, but the archaeological record in the Ragged Island Range remains patchy: limited excavations and preservation biases mean our picture is incomplete. Archaeological evidence indicates repeated coastal occupations, shell-rich refuse deposits, and light architectural features rather than large permanent settlements. These patterns are consistent with a seafaring lifeway that emphasized inter-island connectivity, seasonal resource use, and cultural exchange.

Limited evidence suggests local innovations in pottery forms and ornament that reflect both internal development and influence from neighboring island groups. However, because the current genetic dataset from Flamingo Cay is a single individual, any narrative of migration pathways or origins must remain tentative. Continued excavation and new ancient DNA samples are needed to move from hypothesis to robust regional models.

The genetic signal from Flamingo Cay is compelling but currently very limited: one ancient individual associated with Ragged Island Ceramic deposits yielded paternal haplogroup Q and maternal haplogroup C. Both haplogroups are well-established components of Indigenous American genetic diversity. Haplogroup Q is commonly observed among Native American Y-chromosomes and is interpreted as part of the deep paternal legacy of peoples who peopled the Americas. Haplogroup C on the mitochondrial side is one of several founding maternal lineages distributed across the Americas and parts of the circum-Pacific.

Archaeogenetic context matters: the presence of Q and C in a single island individual fits broad expectations for pre-contact Caribbean populations, but with crucial limitations. With a sample count of one, statistical power is negligible; any inference about population structure, sex-biased migration, or continuity with mainland groups must be framed as preliminary. Comparative ancient DNA from the Greater Antilles and other Bahamian localities remains sparse, and modern Bahamian genetic profiles reflect centuries of contact, migration, and admixture that complicate simple continuity claims.

Nevertheless, this genome demonstrates that Indigenous-linked maternal and paternal lineages persisted in the Ragged Island Range into the late first millennium CE and beyond. Combined with ceramic and archaeological evidence, the genetic data point to island populations that were part of wider maritime networks connecting islands and, ultimately, mainland sources. Future sampling across multiple sites and dates will be necessary to test hypotheses about migration routes, demographic size, and potential sex-biased patterns of mobility.
