In a sci-fi setting, could apes really speak?
I was recently very moved by the movie "Rise of the Planet of the Apes." What I connected with was the way the movie addressed the cruelty towards other species that a lot of the members of ours considers a matter of course, but the inquisitive/scientific aspect of me also noticed some ideas in the movie that I was not sure were really realistic. So my question is: in a sci-fi world like in the movie, could apes (e.g. chimpanzees) really vocalize human speech?
