Phytolith Evidence for the Early Presence of Maize in Southern Quebec
Bibliographic record
Abstract
It has long been believed that maize ( Zea mays spp. mays ) was introduced in Quebec at around A.D. 1000, at the very beginning of the Late Woodland period. The identification and dating of maize phytoliths extracted from the carbonized encrustations on the interior surfaces of Native American ceramic vessels from three sites located in the St. Lawrence River valley, namely the Hector-Trudel, Station-4, and Place-Royale sites, indicate that this cultigen was rather introduced in that area during the Early Middle Woodland period, ca.400 to 200 B.C. These sites provide the northernmost and possibly the oldest evidence of maize consumption in northeastern North America. More samples of maize phytoliths from the same two sites were dated to the late Middle Woodland period, between A.D. 600 and 800, suggesting an increase in the ubiquity and importance of this new crop in the subsistence strategies. Moreover, the identification of an unknown variety of maize points toward the possibility that a new local variety of maize appeared during the process. This process might have been accompanied by a more intensive and complementary collecting of wild rice. Finally, the results support the hypothesis of an in situ origin of the St. Lawrence Iroquoians.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
