Good observations Bob.

My suggestion is that when HG's success led to large population growth,
the large land animals were hunted out.  Simultaneously, the last ice age
was waning and plants/grasses were proliferating.  Humans being the
resourceful folk that we are, turned to grain production to survive.
This meant settling down and not moving around as much, to maintain crops
in one place.  The storage and nutrient density I agree with.  I'm not so
sure about the ease of processing as a reason to go to grains.
