Evolutionary Clues to Why Lefties Still Thrive

This is one of those "Well, DUH" articles.  It's pretty cool, but once brought up, seems obvious.  Ever wondered why, with all the difficulty and disadvantages the left handed face, there are so many?  Al-Jazeera.net reports that evolutionary researches from France have indicated lefties have a serious whup-ass advantage on the right handed. Today we have traced many skills and abilities that are more prevalent in the left-handed (math, music, many creative endeavors), but those don't really explain anything from an evolutionary standpoint.  Actually, i'm not sure this does, either, but it's interesting.
