>>1987009Perhaps. I think one of the major problems when we humans give non-humans tasks in order to test their intelligence, is that we can't be totally sure that the animals will go all in to solve them. Most of the time, we reward them with snacks or fruit for a completed task, but since the (most often captive-bred, and thus, also well-fed) animal might know that it'll be fed at a later occation, it might not decide that solving the problem is worth the trouble.
I'm not sure about the exact circumstances for this webm, but it doesn't really feel like the orangutan knows that she's supposed to nail the nail through the board. She might be imitating someone she saw successfully nail it, but perhaps she only noticed that he was hitting the nail with a hammer, and assumed that there was nothing more to it(the exercise doesn't seem to have any practical application in this case). It might also be that she's merely replciating the typical ape "nut-cracking" behaviour, except she changed the nut into a nail and the rock into a hammer. I think I have to see the entire documentary(and, if any, any ethological/primatological research that examines this behaviour).
