GoKawiilStudy finds chimp mothers actively teach tool use by handing tools to offspring
Researchers publishing in Frontiers in Psychology observed that adult chimpanzees, mostly mothers, model tool-use behaviors like extracting hard-to-reach food, then pass their tools directly to young chimps so they can imitate the motions. The team calls this deliberate handoff a form of teaching, distinct from mere observation, that helps juveniles master foraging technology.
