An archaeologist compared the "leisurely life of the paleolithic" to the 
grinding labour of the neolithic framer. He should know.
Man is a pack hunter; all he had to do was chase an animal into the 
waiting spears of his partners, or if the animal is too big, dig a hole 
for it to fall into, lined with sharp sticks.

Any animal stupid enough to attack an party of the mightiest killers on 
earth soon became extinct.

We can metabolize a high fat moderate meat diet because it is what we 
are designed to eat. Proven by those who have tried it.
