History of Left Handedness or Left Handers
People have time and again wondered why some are left handed whereas others are right handed. But, till now there is no conclusive study that can provide the exact causes of handedness. A person’s preference to use a particular hand can be due to genes, chance or other social or cultural factors.
One popular theory regarding the high prevalence of right handers is related to the functions that each side of the brain performs.
Speech is controlled by the left side of the brain. Now, each side of the brain controls the opposite side of the human body. Researchers believe that since speech and gestures go side by side hence a person uses more right hand gestures while speaking.
This leads to the right hand becoming dominant and the reason you find more right handers than left handers.
