Most animals that show a paw preference are split 50/50 with half of the population preferring one side and the other half preferring the other, yet in humans only 10 percent are left-handed. The video explains what part of the brain controls handedness and language and the connection, or lack of connection, between the two. It ends up raising more questions than it answers, which is an important lesson for scholars to understand.
