I don't see why it should follow that they must have been hunters rather  
than scavengers.
This from my own experience, and from reading of the techniques used by  
paleo man, aboriginal Americans, Inuit etc. Hunting is neither harsh nor  
demanding. Maybe it was, for the stupid, but that rules out paleoman, and  
makes the story irrelevant.

If they were scavengers it would make sense that they needed to flee when  
the predator returned to it's kill, so then speed was required.

Don't try to think too much. It frightens the anthropoids.
