"Look at how tribes like the Bushmen hunt." Well, I know but that's first thing everybody says. What about the way the Inuit hunt or the way the Celts hunted? Where I live, the Indians used to drive pronghorn and buffalo over small cliffs into dry washes. They didn't run, they walked (and later rode).
I guess I'm just not totally convinced.
Yup, and some tribes somewhere lost in time 'hunted' by stealing baby animals and rising them in pens. Or following herds of animals that were somewhat easy to bring down with a spear of sling.
A real scientist does not mix up cause and effect randomly and assume intent. I have often thought the human leg structure was designed *cough* evolved for sitting on a nice padded buttocks for long periods of time. Soooo did we evolve to sit for long time waiting for prey? I use to think scientists put more thought into their work. Now I know better.
