Well, Clyde sure did in the movie Every Which Way But Loose. Orangs are quite clever, and we always knew they were by far the best tool users among the great apes. Their feats of intelligence and escape artistry at zoos are near-legendary, and have included hiding improvised lockpicks in their lower lip - then successfully using them. They've also shown the inclination to make one tool using another tool, which is no small water.
Clyde was a trained ape, of course. So was Chantek, who showed the ability to master sign language, invent new words, lie successfully, and absorb human cultural notions at the level of a young child.
All pretty cool - and potentially disruptive to our notions of where the term "reasonable creature" (which defines some states' murder laws) might begin and end.
Another brick in the wall comes from Erica Cartmill and Richard Byrne at the University of St. Andrews in the UK. They studied orangutans in zoos, but the study focused on how they interacted with each other, not with humans. The kicker? The orangs were consistently using sign/body language among themselves, for specific things, and using the same signals both consistently, and with more emphasis when a response isn't forthcoming (the sign equivalent of talking slower and louder - guess that reflex goes pretty deep).
The use of zoos introduces some complications to the conclusions, but without some kind of anti-grav pack, that stuff is going to be very hard to observe in the wild. If we ever do establish the existence of a similar behaviour pattern in the wild, without human intervention, I think the case will pretty much slam shut on the notion of orangutans as, effectively, "people."
I'm there now. Right beside Philo Beddoe.
