Nearly all living creatures manage some form of communication. The dance patterns of bees in their hive help to point the way to distant flower fields or announce successful foraging. Male stickleback fish regularly swim upside-down to indicate outrage in a courtship contest. Male deer and lemurs mark territorial ownership by rubbing their own body secretions on boundary stones or trees. Everyone has seen a frightened dog put his tail between his legs and run in panic. We, too, use gestures, expressions, postures, and movement to give our words point.
