One bonobo comforts another. Frans De Waal is a scientist who studies bonobos and chimpanzees, animals that are most like human beings. He noticed some natural behaviors that seemed to show that these animals had empathy and a sense of fairness. Empathy means the ability to identify with another and imagine what the other feels. The picture showing a bonobo comforting another with a hug suggests that one animal feels empathy for pain or disappointment the other felt. De Waal conducted experiments that seem to prove that bonobos and chimps show empathy and fairness. Apparently, grapes are highly prized by both kinds of animals. If two bonobos are both given grapes, they are happy but if only one gets a grape and the other gets a cucumber, the one with the cucumber gets angry. They stay angry until they get a grape too...
