   Life wasn't that simple.   
      
   Such places existed well into the time of Homo habilis, and before.   
   In fact, such places had always existed. They lacked the knowledge   
   to exploit them.   
      
   The documentary I recommended claimed that a single individual   
   working for three weeks could accumulate enough of the wild grains   
   to feed four people for an entire year. But they needed something to   
   put in, some place to store -- a way to keep it dry for that year. And   
   they needed to process it. They needed to separate it from the rest   
   of the plant and turn it into something they could cook. So next they   
   needed new tools for harvesting, preparing & cooking this new   
   food.   
      
   AND EVEN THEN IT WASN'T ENOUGH!   
      
   They could only be semi settled. Once they exploited a field it would   
   takes years -- plural -- for it to recover. So the better they got at   
   collecting, storing & processes this new food source, the more mouths   
   they could feed (the higher the population density) the quicker they   
   used up their food sources and had to move on...
