Science is not just a collection of facts. It is the story of man's efforts to find out what kind of world we live in, how it got that way, and what it may become in the future.

The investigation of these mysteries is often more exciting than the facts the scientist discovers. It calls for clever detective work, and the way the scientist tracks down his clues is usually the best part of the story. This new book in the Great Mysteries of Science series tells the tale of one of the thrilling investigations in science.

The story has to do with how we learn. By studying the behavior of animals and the ways in which they learn various things, psychologists have found out a great deal about human learning. This book tells of fascinating experiments in which they have explored the intelligence and learning abilities of dogs, cats, rats, birds, elephants, dolphins, chimpanzees, and other animals—from the dumbest to the most intelligent. From their investigations have come some new ideas on more effective ways to train pets. More important, scientists are gaining a much better understanding of the behavior of animals and human beings.
