   There is just one major snag: 3 of the first agricultural   
   cultures were based on crops that grew locally and was not   
   moved far until much later. It was wheat in Mesopotamia,   
   millet in one place in China and rice another place. The   
   simultaneity of the start of agricultural cultures is another   
   one of these strange coincidences that puzzles me.   
      
   The transport of wheat is another mystery; from what I hear   
   it was once thought that the Aryan people brought wheat to   
   Europe along with their indo-european language. More recently   
   I hear some doubt the Aryan people ever existed and that   
   knowledge of what growing was more of a people-to-people   
   movement. What the currently accepted theory is these days   
   I do not know but these theories do seem to change a lot.

   So one has to look for a naturally ocurring cultivable   
   crop on the southern hemisphere. I would be surprised if   
   it didn't exits.
