I don't mean to pick on you RitaRose, even if it may seem that way.
Way to miss the forest for the trees, Grok. He's saying that the very important social roles of teacher, healer, leader, conflict resolver, etc. we're taken up as needed on a voluntary basis, according to one's inclinations and abilities, because the close genetic and emotional ties of the people in a tribe to each other motivates behavior that fosters preservation of the group identity, in order to mutually increase the odds of survival for each member.
It doesn't mean people were never petty and never corrupt and never awful, just that the basic function of such societies doesn't rely on our narrow, individualistically money-centered views of fair exchange and justice, and also doesn't require the psychotic philosophy of continual expansion, improvement and conquest.
Today I will: Eat food, not poison. Plan for success, not settle for failure. Live my real life, not a virtual one. Move and grow, not sit and die.
My Primal Journal
Do you really think there were certain people designated as cops? Or protectors? What evidence do you have of that?! Why would you need police protection in a paleolithic tribe of probably less than 100 people? You only had large civilizations after the advent of farming.
Sure, there were probably the Elders who were too old to hunt, but you probably had to go through thirty years of hunting before reaching elder status. And I'm pretty sure the medicine man was also the spiritual leader of the tribe. There wasn't much of a division of labor back in the old days.
I can just see it now, Grok growing up 25,000 years ago contemplating his future and deciding on becoming a carpenter for his make believe anarcho-socialist tribe.
On the education topic in particular, you do not understand how education works. Kids could watch all the adults in action to learn from. There was no person necessarily designated as 'teacher'. I'm sure though that there were many ways that kids were educated.
You're applying our society's values to theirs. It doesn't work to do that. Why would or should they care about Euclidean geometry? Poetry and history are found in story-tellings around the campfire. Psychology is innate to talk and think about. Let me guess...the next thing you're going to mock is who the teacher was for writing/reading.
