Subject: Does the hunting instinct control many of our actions?

What I mean by "control our actions" is does it provide the basic 
model for how we carry out our lives?  As Desmond Morris says, 
are we a "supertribe" that maintains its hierarchical structure 
and roles in the modern world?  As an educator in the humanities, 
I suspect that our classrooms are "tribes", and that literature 
basically is a linguistic derivitive of the need to hunt.  If 
primitive tribes hunted, then returned to tell the tale to the 
rest of the tribe, was this, instead of the agricultural cycle, 
the true model for what was to become literature?  I see in the 
agricultural cycle the leaving of home,  entering unsafe 
territory, hunting the beast, then returning home through 
dangerous territory (and fighting off scavengers in the process), 
then (hopefully) returning home triumphantly?  Where can I read 
more about this?  I see this utter primitiveness in Hemingway's 
_The Old Man and the Sea_.  What scientists lay out this pattern 
really well?  I've found only snippets on the idea.
