A compelling and sometimes provocative series using both anthropological and natural history footage to compare and contrast the origins of human and animal behaviour: The Need To Succeed examines how humans and animals establish and maintain their place in society; The Need To Breed compares the way humans and animals reproduce; The Need To Feed looks at how the behaviour of all animals is more influenced by what they eat than any other factor.
