http://www.independent.co.uk/news/s...earning-to-talk-say-researchers-10456969.html Researchers say they have "found examples of Koko performing nine different, voluntary behaviors that required control over her vocalisation and breathing." "Koko bridges a gap. She shows the potential under the right environment conditions for apes to develop quite a bit of flexible control over their vocal tract. It's not as fine as human control, but it's certainly control." How long before we are forced to bow down to our ape overlords?
