And so you could say out of necessity, maybe a tribe here or a little group there started to say, hey, what if we started to, if we started to domesticate some of this cattle or if we started to plant crops, all of a sudden they would start to have a higher density and their population could increase. And not only would they be able to survive, but they could also be very dominant in things like conflict. Once you start having agriculture and as agriculture advances, as I mentioned, these people could be more sedentary. They wouldn't have to move around. They wouldn't have to move around all of the time. That allows them to create even defensive structures. You could have specialization where not everyone is having to worry about specialization.
