I'm generally against forcing animals, using punishment, to learn to perform stupid tricks for our amusement, but I think this complex set of executions demonstrates a heretofore unrecognized level of primate intelligence.
I realize this sort of thing is illegal, unethical, immoral and violates every self-imposed code we humans have for our conduct toward other living things, BUT, wouldn't it be cool if we could engineer at conception a human Broca's Area(speech center) in the Bonobo brain along with the concomitant vocal chord genes necessary for speech? The FOXP2 gene is really the only genetic difference in brain speech development between Bonobo's and humans. Then we could really asses the intelligence of these creatures.
The fact that it can be done means that somebody somewhere WILL do it, and I for one, can't wait to see the results.
