You probably don't think about left-handed folks until you have to sit next to a lefty at the dinner table and end up getting elbowed in the ribs. Lefties represent only 10 percent of the world's population, yet they've been such a fascination for so long that study after study has been conducted on what makes them so unique. But while we now know that lefties are normal folks, history wasn't always so kind to our left-handed friends. In the Middle Ages, being a leftie was enough to get you accused of being a witch , and in the 18 th and 19 th centuries, left-handed children were forced to use their right hands in schools, which was dreadful - have you ever tried switching hands to write? It's not easy. Those biases persisted well into the 20 th century: In the s, the Soviet bloc even had official policies against lefties.

In human biology , handedness is a better, faster, or more precise performance or individual preference for use of a hand, known as the dominant hand ; the incapable, less capable or less preferred hand is called the non-dominant hand. There are several theories of how handedness develops in individual humans. Occurrences during prenatal development may be important; researchers studied fetuses in utero and determined that handedness in the womb was a very accurate predictor of handedness after birth. One common theory as to how handedness affects the hemispheres is the brain hemisphere division of labor. Since speaking and handiwork require fine motor skills, its presumption is that it would be more efficient to have one brain hemisphere do both, rather than having it divided up. Since in most people, the left side of the brain controls speaking, right-handedness predominates.
