It's probably about as easy to lay out a big case that humans evolved for rock climbing and swimming. We out perform plenty of animals at that.


When you compare the meat yield of persistence hunting vs. rock climbing, PH's case does come out quite stronger.


I doubt anybody has empirically compared anything with regard to persistence hunting.

Might as well talk about meat yields of diving for shellfish. Some people think this was a major human activity.

It's all supposition.


Well, we do have a rather pronounced diving reflex.


I was under the impression that ours was one of the weakest of the mammals...


Compared to marine mammals yes. But I've read someplace that ours is remarkably strong for a supposedly completely non-aquatic mammal.
