Abstract
This chapter evaluates predictions that the origins of at least some gestures of human infants are shaped through ontogenetic ritualization (Clark 1978; Lock 1978; Tomasello 2008). To do so, we examine the development of five gesture types in four children between the ages of 6.5 and 11.5 months. This analysis supports a comparison between those gestures thought to be ritualized ( pick-me-up, graspindex ), with those that are socially learned ( wave, clap, clasp-hands ). Although some limited evidence for ritualization is found, developmental similarity amongst the five gesture types is strong. Through comparisons of gesture ontogeny between human and non-human primates, we explore the possible reasons for this result.

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 it
