Brain and Handedness, 3

How soon can handedness be identified? Researchers who studied fetal handedness concluded that handedness during gestation was a very accurate predictor of handedness once the baby was born. Something on the order of ninety-seven percent of toddlers demonstrated a handedness preference. Right-handers tend to use the left cerebral hemisphere more efficiently and may excel in math and science and verbal fluency. Left-handers on the other hand have an especially fine use of the right hemisphere, males even more than females. Many famous individuals were reportedly left-handed, including: Leonardo da Vinci, Michelangelo, Queen Elizabeth the II and her grandson Prince William, Bill Clinton, Barak Obama, Ruth Bader Ginsberg, an estimated fifty percent of famous entertainers, many artists, and a host of sports figures. If you are interested, Wikipedia provides an extensive list of left-handers along with their pictures. More tomorrow
