So, just saying maybe. If you know the Migratory path studied by our Ancestors, now include pit falls run them into a trench. Several spears and cut it up before the Saber Tooth comes or more coldly even then let it them eat and stab the crap out of them. Defeating your enemy.I wouldn't put too much in that running down theory. I saw a show on Nova about that many years ago.
I tried for over three hours to run down some antelope once. In the grass flats with an old mercury. They led me in circles at 35-40 MPH for hours and never broke a wind.
I'm not kidding you...for hours and they did not tire. Tried with deer and elk too......but they always went for rough ground.......while the antelope thought it was play.
Besides....we're much too lazy.....I'll bet we had throwing rocks, boomerangs, spears and traps within the first week of hunger.
Just saying somehow you still have a belly button, and humans survived.
