This is a clip from the Life of Mammals (Food for Thought). On one hand, I think it’s fascinating–orangutans are amazing at picking things up just from observing humans! However, all of these behaviors are a result of living in captivity among humans. As Attenborough points out, the orangutans spontaneously engaged in these behaviors–they weren’t trained to do so. However, they nonetheless are engaging in these human-like behaviors because they’ve spent so much time around and observing humans.
