As a person who is almost completely left-handed I find the following article as complete drivel. Well, not completely. I am instinctually a lefty. So much so that I wrote with both hands in grammer school for a few lower grades to accommodate the teachers who were agast at my preferences. In the USA 15-17% are lefties. Famous lefties include current world leaders, artists, actors,authors, sculpters to an inordinate degree based on average population studies. Lefty IQ is generally high than righties, and 3-D spacial relations is a lefty specialty. It is not inherited.-The theories expressed in the article are illogical uses of the postion of functions in the brain. The brain is too plastic to reach the conclusions presented.
