Scientific Study Explores Why Nearly All Humans Are Right-Handed

A scientific study examines the evolutionary reasons behind human handedness, suggesting that having a specialized dominant hand may have provided a competitive advantage in human development. The research explores why the vast majority of people across cultures and throughout history have been right-handed, pointing to potential evolutionary benefits of hand specialization. The findings contribute to understanding human motor development and the biological basis of lateralization in the brain, where one side becomes dominant for certain functions.
