Most people are right-handed (about 90%) due to a combination of genetics, brain lateralization (left-brain control of the right side), and evolutionary advantages, with the left hemisphere specializing in both language and fine motor skills, creating an efficient system for the right hand. While genes contribute, environmental factors, fetal development, and cultural pressures also play a role in this widespread human trait, which likely emerged with tool use in our ancestors.
