Science Explains Why So Few People Are Left-Handed
Posted By: Dennis - Source: Web
I'm no lefty, in fact my left hand is pretty dumb when it comes to doing precision tasks like writing but I can assemble a motherboard, rebuild an engine, draw and paint with both my hands, assuming the right is involved.
Left-handers aren't very common. In fact , they only represent about 10 percent of the human population. But a new study suggests that the reason lefties are in the minority isn't anything suspect—rather, it boils down to the fact that the human race cooperate more than they compete.
Not sure I believe that the reason for handed'ness is based on the social order of humans but it seems logical.
