I always assumed that hunter gatherer division was mostly down to the individual, some traits make some better at hunting than others.
I struggle to locate static objects, I for the fucking life of me just can’t see it. I’ll be looking for something and either look right over it or walk past it multiple times
But if I go outside and look in the trees I can spot all the squirrels within seconds. Not like that’s a talent or anything special, but my point is that I’d starve if I had to look for food in the brush, and likely I imagine these types of traits are what defined who did what job, meaning who was good at what, and likely considering lots of hunting was endurance based and not skill based at all, then most adults probably participated to some degree.
I’ve also gone shroom hunting and had to come back empty handed because I can’t see the god damned things.
