Dolphins chat and elephants care for each other, while monkeys steal and rats can sometimes share; humans are not alone in our ability to think about ourselves, make plans, help each other, or participate in deception. In this book, Nancy Castaldo introduces readers 12 and up to the scientific method and details how best to observe animals in their natural settings, as well as explaining how and why scientists are trying to unlock the secrets of animal empathy, communication, tool use, and social societies. Color photographs appear throughout, and the book also includes a glossary and info on web resources for further study.
