Then why do you propose human standards a comparision? The chimp upper
body is different from a human's.

The chimp's strength has been established. Tho smaller than a human,
they can easily knock one down.

But we're talking about defense against four legged predators,
not humans.

How about _many_ stray rocks, thrown by many chimps/humans? Being
hit by one is a start, being hit by more establishes the desired
response: they keep their distance. Do you jog? Had dogs confront
you? All I have to do is reach to the ground and pretend to pick up
a rock. Response: the dog stops his advance or even backs up.
Predators are no less capable of making this association.

In the plains? Assuming they traveled alone, instead of the
groups they are found in, then yes a chimp is at the same
disadvantage any lone animal would find itself in...

There are numerous recorded interactions of modern human/predators.
Hikers, campers, etc. Without weapons in many cases. Some are
injured, most are not. Scream, make noise, throw things.

The same can be told of early peoples and their relations with
predators. It must be effective since they survived...
