Once, when giving a talk, Jane told the amazing story of watching a group of young male chimpanzees walk up a small river they had never visited before. As they came around a sharp corner, they suddenly saw a huge waterfall, crashing majestically into a pond. At first they froze, amazed, taking in what they had just encountered. Then, she said, the young chimps raised their arms above their heads and began to dance with joy. Their response, Jane told the audience, is best understood as awe and wonder.
