according to Brain, the types of tools (stone and bone) found at Swartkrans do
a very good job of digging up bulbs, tubers etc. of the sorts found in the
area today. It seems to me that even if they only did the job a bit better than
could be done by hand, that's better than nothing and the ability to make such
tools would then be selected for (as discussed in my posting to Rob Quinlan).
Also, don't forget the use that certain chimp societies make of hammers and
anvils to crack nuts (although how much all the invested effort pays off
energetically perhaps varies, see Gunther and Boesch). I don'tknow the answer
really....nature, green in tooth and claw....
