Interesting question, and I have some thoughts, but gained from reading about anthropology, which goes back into the time of the hominids rather than the stone age:
Why is hunting regarded as riskier than gathering? A group of humans staying in one place would be smelled a mile off by a predator.
How often did they hunt? Chimpanzees do hunt in groups of males, but not very often. Bonobos, it seems, don’t hunt at all.
What constitutes “hunting”? Most anthropologists seem to include scavenging as hunting. There’s evidence in Jersey of a lot of animal bones plus hominid tools at the bottom of a cliff. And those animals include those in their prime, not just the old or the young. That’s driving a herd over a cliff, which is also counted as hunting. I could imagine that every able-bodied person, whatever their sex, would be involved in that.
And then there’s the question of what “gathering” or “farming” involves. There’s no evidence, but I can’t imagine that young boys and old men would simply be sitting back at the cave.
So, I think like all things to do with humans, it isn’t quite that simple.
Nuffaluff - love the discussion on games consoles in the Stone Age.
