I have to give a presentation tommorow on the evolution of human "language ability." (That is, the way kids can learn a language with very little instruction/negative feedback.) Basically, they think this evolved to help deal with social situations. The chiefs of primitive tribes (please excuse the anecdotal evidence) are often both extremely eloquent and reproductively successful. Some hunter-gatherer societies spend enormous amounts of time talking, arguing, gossipping etc., so being good at these things is probably selected for.

The scorpion's tail seemed a hell of a lot harder to explain.
