Last week I asked my Chinese painting prof if we could try calligraphy, and he said "no". "Left-handedness is too much of a problem, movements would be too awkward with the brush. - So what happens with the small percentage of natural left-handed in China? - It's beat out of them. I still use chopsticks with my left hand, because it's tolerated, but writing is just unacceptable." So yeah, it's a complete mystery. Recently there were some interesting papers looking at laterality from a more general point of view (which is a bit touched on with the simian examples in the article). Given that there are strong genetic factors involved, it's not surprising that with tools becoming more prevalent in complex societies there would be a human co-evolution.
