Neolithic?
Seriously?
We’re going to go back to the Neolithic period to justify teachers boinking teenagers they are responsible for?
Reevaluate your moral compass.
Yes. We are still the creatures that emerged from the Neolithic. That’s the last period in which humanity was affected and molded by evolutionary mechanisms.
And about that time humanity invented technology. Which has changed ever more rapidly, changing the human environment, physical and social, with it.
Everything since has been, in evolutionary terms, a constant state of biological whiplash. We have not had time to adjust to changing conditions throughout selection pressure.
A great mass of modern problems comes from this.
A “moral compass” is one of the human coping mechanisms for these problems. Not guaranteed to work.
