Both controversial and influential at the time of its publication, Ardrey's Territorial Imperative did much to foster wide public interest in the origins of mankind. With an strong emphasis on mankind's sense of territory as a driving developmental force, Ardrey builds the argument that man's origins were African rather than Asian, and that he is driven by inherited instincts to acquire land and defend territory.
