|The Naked Ape|
Mr Morris explains in his book the human behaviour and culture from a zoological point of view. This was quite provocative in his time, and reading the book nowadays you can still feel your face firing when the author gives his interpretation of many facts under a sexual view.
Anyway, the book contains many interesting explanations, very funny most of the time but a little bit scary others. Highly valuable for business dealing with people i.e. communities, customer, employees.
Even more interesting and modern, Mr. Morris is the author of another useful reference, titled Peoplewatching: The Desmond Morris Guide to Body Language. People watching is "is the act of observing people and their interactions, usually without their knowledge". Using people watching with scientific aims produce interesting insights for social science. Therefore, this reference is now waiting in my reading shelf.
So yes, highly recommended!
