Ouh, i recently learned that war is likely a product of humans abandoning their nomadic lifestyle for settlements and agriculture.

Yes, there was certainly violence between humans before, but since tribes were always on the move, resources at their current location weren’t as valuabe/ worthy of defence. No berries here? Guess we’ll move on. Another tribe fishes here already? What is increasing your survival chances? Moving along the shore, looking for a different fishing spot or violently take the occupied one?

If you grew crops on fields it absoluetly made sense to defend your location. You can’t take these plants with you, but they’ll yield a lot of food you wouldn’t want, or could affort to lose.
