The Naked Ape: A Zoologist’s Study of the Human Animal by Desmond Morris, first published in 1967. The book explores human behavior and society from a zoological perspective, examining the ways in which humans are similar to and different from other animals. Morris argues that humans are essentially animals, and that many of our behaviors and social structures can be explained by looking at our evolutionary history.

The book covers a wide range of topics, including human sexuality, aggression, communication, and culture. Morris uses examples from both human and animal behavior to illustrate his points, and he challenges many commonly-held beliefs about human nature. The Naked Ape was a controversial book when it was first published, but it quickly became a best-seller and has since become a classic of popular science writing.
