Interesting article on Discovery about the motivations behind the rise of agriculture in early human societies:

People turned to farming to grow fiber for clothing, and not to provide food, says one researcher who challenges conventional ideas about the origins of agriculture.

Ian Gilligan, a postgraduate researcher from the Australian National University, says his theory also explains why Aboriginal Australians were not generally farmers.

Gilligan says they did not need fiber for clothing, so had no reason to grow crops like cotton.
