I wasn't disputing the advantage of human anatomy, I was relating it to natural selection.
The idea of natural selection in humans gets a little confusing when you consider the importance of man’s brainpower and his unmatched ability to share knowledge and skills with his pack mates.
I would suggest to you that in humans the only natural selection pressures of major significance are those that select one pack of humans’ warfare technology over another’s. I don’t see genetics being terribly important. The most profound feature, imo, is the genocidal utility of a tribe’s weaponry...and the effectiveness of his defenses and fortifications.
Man is so extremely head and shoulders above every other creature on the planet, man is not in competition with animals. i don’t even think man is competing with man for ability to ingest animal protein.
Man is in competition with man for power and control over man.
