Diversity of Lifeways in Early Antillean Societies: A Multi‐Isotope Approach
Bibliographic record
Abstract
ABSTRACT Objectives In this paper, we sought to examine whether people with different lifeways, as evidenced by their mobility patterns and dietary practices, inhabited the Antilles in early precolonial time. We also aimed to explore spatiotemporal trends. Materials and Methods New and previously published enamel strontium, oxygen, and carbon isotope data were combined with bone apatite carbon and bone collagen carbon and nitrogen isotope data to assess the mobility and diet of 146 individuals from eight early precolonial sites from Cuba. Results At least three patterns of mobility, associated with different dietary signals, were identified. In contrast with the low 87Sr/86Sr and δ13Cen variability found in Canímar Abajo (CA) between bce 1320 and 807, more variability in dietary practices and higher mobility was apparent in later groups. Between bce 116 and 241 ce, individuals from Playa del Mango showed high mobility within the Cauto region, likely associated with food procurement between inland and coastal areas. From at least 174 ce, a moderate pattern of mobility and a diversity of dietary traditions could be observed among groups from western sites. At least three general dietary patterns were observed, ranging from a 100% C3 diet to 70:30 C3/C4 and, in the case of CA, a higher dependence on marine/C4 resources. Conclusions The differences observed in both mobility and diet between and within populations support the notion that groups with different lifeways inhabited the Antilles in precolonial times. This diverse mosaic of cultural traits defies attempts to group them into broad categories for regional studies of biological and cultural traits.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
