Why some of us lean left, while the majority of us lean right

Have you ever noticed that most people use their right hand to write, eat, or throw, whereas some use their left? For ages, this basic habit has baffled parents, educators, and even scientists. According to current research, handedness is a fascinating combination of genes, environment, and brain wiring rather than only a choice.AN EARLY BRAIN CHOICE The two parts of our brain are referred to as hemispheres. Language and fine motor skills are controlled by the left hemisphere in almost 90% of persons, meaning that the dominant hand is the right one.In roughly 10% of cases, however, this wiring appears differently. Left-handedness may result from their brain's tendency to divide tasks more evenly or from the right hemisphere taking the lead.

When nerve connections are still developing, this process begins before to birth.Although some genes have been identified by scientists as being associated with handedness, none of them by itself can determine the outcome. Rather, handedness seems to be influenced by a variety of minor genetic influences as well as fetal variables including hormones, stress, or even the way a baby lies before birth. Learning in early childhood can also throw off the equilibrium, particularly if a youngster tries using both hands before choosing one.Culture also has a role. Being left-handed was stigmatized for generations. "Sinister" actually means "left" in Latin, and many schools used to make students use their right hand instead. Even if these customs have diminished, the world is still mostly made for right-handers—just take a look at cricket equipment, tables, and scissors. However, well-known leftists like Barack Obama, Sachin Tendulkar, and Leonardo da Vinci serve as a reminder that the left hand has created some of the greatest minds in history.
