Are long digits correlated with high forepaw dexterity? A comparative test in terrestrial carnivores (Carnivora)
Bibliographic record
Abstract
The relationship between manus proportions and forepaw dexterity in 33 species of carnivores (Carnivora) was examined. Both the analysis of "raw" data and independent contrasts revealed no significant correlation between the metacarpalphalanx (MCP) ratio and forepaw dexterity. This result was corroborated by a common origins test, which indicated that changes in the MCP ratio were not coincident with changes in forepaw dexterity throughout carnivore evolution. Together, these results suggest that the morphological basis for variations in manipulative behaviour may be quite complex. Other morphological features, such as manus and carpal shape and myology, may play a critical role in forepaw dexterity, but are not manifested as changes in manus proportions. Behavioural observations also suggest that manus proportions may be correlated more closely with locomotion rather than non-locomotory forepaw usage.

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.
