Primate intelligence is a fascinating study. For one thing, it easilly dispels the idea that animals are somehow "dumb". What I find fascinating is the potential impact of our teaching of primates. For example, were Koko to teach her signing to others, presumably that would continue to successive generations. Eventually, the communication would become integrated, much like with humans. Who knows where it could go from there?

Sadly, I think most of this is largely academic as most people seem to have very little interest in this area. I suppose that until companies or governments see profit potential, the area will not recieve a great deal of backing.

I suppose it's not surprising, though, given that it is hard enough to find support for taking care of our own species, much less any other.

It would be awesome if Koko taught signing to her children.
