Yeah. If even only one comes back, he might be the strongest or whatever, but he might also be weak. You’d probably also want to keep weaker men back at the village rather than on the hunt because they have the lowest chances of survival (thought I think that might be kind of overstated, I think it’s kind of unlikely that everyone randomly dying on a hunt was some sort of common enough occurrence, I think individual instances of tragedies or freak accidents are more likely). If you’re keeping back the weakest men, you’re also going to have weaker men going forward, which then leads to the village dying out in the long term. You also see less genetic variance if all the strong men die and the weak men are left reproducing, which is also bad, yadda yadda.
So I’m not sure I buy the whole like, men are expendable, which is why they’re stronger, or why they’re hunters more commonly, or both. That kind of at face value reads as a kind of macho posturing sort of idealism.
