New research suggests upright walking and brain growth shaped human right-handedness. This evolutionary process began when hands were freed from locomotion duties. As hominins evolved, right-hand preference grew stronger with increasing brain size. Larger brains encouraged hemisphere specialization, making consistent hand use more common. This explains why most humans favour their right hand over others….
