Wild Justice and Moral Intelligence in Animals

A rat in a cage refuses to push a lever for food when it sees that another rat receives an electric shock as a result. A male Diana monkey who learned to insert a token into a slot to obtain food helps a female who can’t get the hang of the trick, inserting the token for her and allowing her to eat the food reward.
