Desmond Morris 
The Human Zoo 

A must-read for anyone who has ever wondered why people do what they do, from the popular author of The Naked Ape.
This study concerns the city dweller. Morris finds remarkable similarities with captive zoo animals and looks closely at the aggressive, sexual and parental behaviour of the human species under the stresses and pressures of urban living.
‘Compelling and absorbing…Morris is concerned with the tension between our biology and our culture, as it is expressed in power, sex, status and war games’ New York Times
