When the baboon leader is eating, as long as he yawns and exposes his sharp teeth, he will be frightened and shy away from others, and no one will dare to fight for food.

Therefore, the low ranking lions always turn their heads to one side, avoiding the eyes of the leaders and elders, and yawn quietly.

The researchers found that yawning infection also exists in wolves.
