Researchers have discovered finger flutings made by young children in the Rouffignac cave system in France, indicating that the cave may have been a prehistoric art school. The flutings were too steady for a toddler, suggesting that an adult guided the child's hand while teaching him or her. Some of the drawings were high on the walls and on the ceiling, suggesting that the children were lifted. The researchers were also able to tell the children's genders from the shape of the fingers.
