Arawak Voices of the Caribbean

From the wind-swept coasts of the Orinoco basin to coral shores across the Caribbean, the cultural identity labeled “Arawak” emerges in the archaeological record as a constellation of boat-using communities and ceramic traditions. Sites in this dataset — Punta de Chateaux peninsula, Anse à la Gourde (Guadeloupe), Cueva de los Esqueletos and El Morrillo (Cuba), Lavoutte (St. Lucia), Las Locas (Venezuela) and Preacher’s Cave (Eleuthera, Bahamas) — preserve ceramics, burials and midden deposits that mark centuries of maritime connectivity between mainland South America and island archipelagos.

Archaeological data indicates sustained movement of people, ideas and goods during the Ceramic Period (broadly overlapping the samples here). Lavoutte-style pottery in St. Lucia and related ceramic forms in Guadeloupe and Curaçao suggest shared technological practices and networks of exchange. Limited evidence suggests these connections were oriented along prevailing currents and seasonal voyaging routes rather than single, rapid colonization events; instead, island colonization appears episodic and regionally varied.

Chronologically, the material culture in our sample set spans from the earliest dated contexts around 800 BCE through late pre-contact centuries. While stylistic similarities link many sites, local adaptations — in settlement pattern, subsistence emphasis and mortuary treatment — underline a mosaic of Arawak cultural expressions rather than a single uniform society. Ongoing excavation and targeted radiocarbon dating remain essential to refine the timing and pathways of these movements.

Fifty-two ancient genomes from this Arawak-associated dataset span 800 BCE to 1650 CE and originate from Cuba, St. Lucia, Guadeloupe, Venezuela, Curaçao and the Bahamas. The paternal lineages are dominated by Y-chromosome haplogroup Q (26 individuals), with a small subset assigned to Q1b (2 individuals). Maternal lineages show a mix of Native American founding haplogroups: mtDNA C (14), D1 (10), B2j (6), A2 (5) and C1b (4).

These patterns align with broader expectations for Indigenous American groups: haplogroup Q is a common paternal lineage among many Native American populations, while A2, B2, C and D1 are typical matrilineal markers tracing back to the initial peopling of the Americas. The distribution of haplogroups across islands and time suggests a degree of continuity between mainland source populations (notably northern South America) and island communities, consistent with archaeological models of Orinoco-to-Caribbean dispersals.

Caveats: although 52 samples provide meaningful resolution, sampling is uneven in time and space. Temporal span across more than two millennia means later samples (post-contact centuries) could reflect demographic shifts, including contact-era admixture, which must be evaluated with genome-wide autosomal data. Some sites contribute only a few genomes, so site-level inferences remain tentative. Combined archaeological context and ancient DNA, however, strengthen the inference of long-standing indigenous ancestry in these islands and illuminate patterns of regional connectivity and local differentiation.
