Left handedness=better spatial memory?

This is yet further data to put with all that stuff about left and right brain and evolutionary biology. The jjury is still out, but studying chimpanzee brain and comparing them with humans seesm to be helping progress; it now looks like language is not wspecially implicated in left- or right- handedness, if chimps are anything to go by. It'll probably feed even more of those pop science and mysticism ideas about being left or right brained.
