The chimpanzee is one of our planet's best-loved and most instantly recognisable animals. Splitting from the human lineage between four and six million years ago, it is (along with its cousin, the bonobo) our closest living relative, sharing around 94% of our DNA. First encountered by Westerners in the seventeenth century, virtually nothing was known about chimpanzees in their natural environment until 1960, when Jane Goodall travelled to Gombe to live and work with them. Accessibly written, yet fully referenced and uncompromising in its accuracy and comprehensiveness, this book encapsulates everything we currently know about chimpanzees: from their discovery and why we study them, to their anatomy, physiology, genetics and culture. The text is beautifully illustrated and infused with examples and anecdotes drawn from the author's thirty years of primate observation, making this a perfect resource for students of biological anthropology and primatology as well as non-specialists interested in chimpanzees.
