Ride, Ride, Ride, Let It Ride: Pathological Lesions in Horse Skeletons Related to Riding.
Bibliographic record
Abstract
The last 30 years have seen researchers working towards determining the earliest date of domestication for the horse (E. caballus), using osteological and pathological changes to a horse’s skeleton to infer evidence for riding—a key signature of domestication. This article provides an investigation and evaluation of the methods used, testing them on the skeletal remains of 12 horses of unknown provenience and history from Alberta, Canada. These methods include studies on the skull (cranium and mandible), the dentition (teeth), the spine, and the metapodials (lower leg bones). Overall, three of the horses exhibit osteological changes consistent with riding, three have ambiguous results, and the remaining six do not show sufficient changes. The limitations of the methods, the collections, and those of the researcher, are discussed in relation to the findings.

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.
