One problem. Admittedly, the processes you describe seem to be valid but
I think you are "progressing" tool manufacturing farther than it need
be. Using a stick to dig up plant tubers is so much more logical to me.
Hypothetical situation. Robust A. comes along and finds likely food
source. He (gender neutral) looks around sees a nice stick or broken
branch and goes to work digging up his find. After successfully digging
up the tuber he discards the stick....no energy lost but much energy
gained. The robust A. had no reason to carry around a stick that has
been painstakenly fashioned and sharpened to a perfect point (if he
wanted the stick he picked up to sharp, all that had to be done is rub it
against the ground or a handy rock.) neither does he need to carry around
a stone tool, as basic as it may be, that must be maintained and most
importantly must be _carried_. Robust A. didnt have pockets or pouches
to put it in. Well, thats my logic.....hope it makes sense and that Im
not too far off. I would love to see a bibliography on the sources you
used....I am always willing to be proven wrong.
