You could have specialization where not everyone is having to worry about specialization. Not everyone is having to worry about food all of the time. And so you could develop warriors. You could have technology developing, especially weapons. And so not only would that tribe or that group be able to get higher density, but they would be able to defend their property. In fact, they would probably care a lot more about property because they use it to farm versus hunter-gatherers might just view that as their territory that they wander over in order to find food. Now, whatever the actual cause of the birth of agriculture, it has had profound implications on our society.
