   For a hg group the ratio of plant to animal foods eaten is directly a   
   function of what the enviromment supports.  This is largely a product of   
   latitude and seasonality.  Humans being able to easily digest just about   
   anything thrive on any ratio of plant to animal foods that includes all   
   that is required for proper metabolism.  When proto-humans started using   
   meat some 1.5 million years ago it started them on the way to being able to   
   inhabit all parts of the globe, and they did.  That record is followed now   
   by the animal parts they left behind.  The out of africa model shows huge   
   piles of shells from marine animals as a principle food source that allowed   
   them to follow the sea shore eastward into s. asia.   
      
   That is the long and short of what is known scientifically.  This McDougall   
   fella is quite sloppy with his facts.  He is an md not a scientist.  The hg   
   groups that live on almost all plant matter he proposes do not exist.   
   There are no veggie alone or near so anywhere, none.  All hg groups eat as   
   much animal products as can be gotten.
