Orangutans have one of the slowest-paced life histories all mammals. Whereas life-history theory suggests that time to reach adulthood is constrained by needed adult body size, needing-to-learn hypothesis instead it limited acquire adult-level skills. To test between these two hypotheses, we compared development foraging skills and growth trajectories immature wild orangutans in populations: at Tuanan (
