Why are 90% of people right-handed? Evolutionary biology explains the mystery
Most humans favour their right hand, a trait deeply rooted in our evolutionary past. This dominance, linked to language processing in the left brain and the precision needed for early tool use, has persisted for millions of years. While left-handedness offers a strategic advantage, the efficiency of a dominant hand has shaped our species.
