 How is the evolution of 'atomic' instincts explained?
 By 'atomic' instinct, I mean a complex instinctual
 behaviour such as constructing a beehive.  The initial
 advantageous mutation must be how close to the fixed
 evolution-selected instinct?  Did the construction of 
 beehives start with a bee with a mutation that just
 caused it cough up a lump of wax?  An amorphous behavioural
 mutation too far from the finally selected stable instinct 
 seems unlikely to converge to the final instinct no matter
 how many generations pass.  It's clearly not magic or divine
 intervention that does it, but could there be some
 lamarckian channel that allows for accidentally performed
 proto-behaviours to be incorporated into the genome?????
