I know a couple of guys who's bloodlines should have long since vanished. :-)
My theory: "Men performed significantly better on a series of spatial tasks"
Comes from years of peeing standing up. We've been urinating in 3 dimensions.
I think that hypothesis is almost as valid as the one in this study!
So all that silly bickering over on the AP orienteering threads about map scale was maybe important afterall. (Map) size matters. ;-)
