A QUESTION….Here’s a question for the evolutionary psychology folks: what’s the deal with handedness? It’s pretty clear that being right-handed or left-handed is innate, not learned, and therefore ought to be the result of some kind of evolutionary pressure. But what? My cats, for example, seem to be equally dextrous with both paws, but I’m not. So what happened to us?

(My real guess is that it’s just a (fairly) benign side effect of some other brain development that’s genuinely useful, but that’s cheating by ev psych rules. You need to come up with some plausible story. So let’s hear it.)

(And yes, I’m making fun of the ev psych folks even though I basically support their enterprise. So sue me.)
