Body Language

S1 E1: In the Amazon, a bald uakari monkey does a jig before urinating. In Africa, a cobra spreads out its ribs to form a hood at the sight of another creature. In the U.K., an alpha male wolf places his chin on the back of a pack member. What are these animals trying to communicate through these gestures and poses? Scientists have spent years studying the body language of creatures great and small and are finally learning to decode the signals they’re sending, whether it’s to ward off a threat, find a mate, or uphold a social structure.
