Science has discovered a great deal about why being a lefty shows up in only 10 percent of the world’s population. A study found that lefties are probably left-handed because of a balance between competition and cooperation in human evolution. Cooperation favors same-handedness (sharing tools), and competition favors the unusual (southpaws have advantage in a fight.) The 90-10 ratio of right-handed to left-handed has remained stable for over 5,000 years. Source: LiveScience.com
