Socially‑initiated learning in orangutans

Wild Sumatran orangutan youngsters often learn about food not only by individual exploration but by 'peering'—sustained watching that stimulates exploration for up to ~2.5 hours—so social cues trigger individual trial behavior. In a 12‑year field dataset, social learning events outnumbered individual exploration about fivefold, and individual differences in responsiveness to social cues predict adult diet breadth. — Shows cultural transmission mechanisms in great apes are measurable and influential, which matters for debates about human nature, education, animal culture, and conservation strategies that protect behavioural as well as genetic diversity.
