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
