THE PRECERAMIC AND EARLY CERAMIC PERIODS IN BELIZE AND THE CENTRAL MAYA LOWLANDS
Bibliographic record
Abstract
Abstract This introduction to the Special Section provides a summary of our current understanding of the first humans and the first Maya in these regions and presents seven articles that examine these critical periods from varied, intersecting perspectives. The Introduction begins with a brief history of early preceramic research (primarily in northern Belize) and provides a current chronology for the Paleoindian, Archaic, and Early Preclassic periods. The Paleoindian and Archaic (ca. 11,500–900b.c.) periods are discussed in terms of the origins of the first peoples in these regions, lithic technology, subsistence, and early ritual. Next, a summary of archaeological evidence for the transition to the first villages (ca. 1200–800b.c.) is provided, with examinations of a horticultural lifestyle, the earliest ceramics, increased socio-economic complexity, new ideology and ritual practices, and developing social inequality. Proto-Mayan and Mayan languages—their dating, origin, and early lexicon—are discussed in relation to the first Maya. Material culture and language are explored with regard to conceptions of Maya culture.

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.
