Ever thought being left-handed was a disadvantage when it comes to facing the predominantly right-handed world? Turns out it's just the opposite: Right-handers are so conditioned to compete against other righties that a southpaw's angle of attack comes as more of a surprise. While this has been documented in sports such as baseball, where a left-hander's chances of victory are better than average, until now no one realized that it also partially explains why lefties still exist. Last year, French researchers Charlotte Faurie and Michel Raymond, of the Institute of Evolutionary Sciences at the University of Montpellier, studied why the left-handed—roughly 10 percent of the population in the West—haven't been naturally selected out over millennia, given that lefties suffer from higher incidences of weakened immune systems than right-handers. The duo tracked homicide rates in primitive societies in which hand-to-hand combat is the primary form of conflict and discovered that right-handed opponents are being killed off at a disproportionate rate—one tribe had 17 percent more lefties than the Western norm. The next time you face off against a lefty in a tennis match or bar brawl, you might want to keep this in mind.
