What is william howell's argument in "back of history (man in the beginning)? "

This brings us . . . to the meaning of the so-called Neolithic revolution. If you generalize, and take the typical effects on culture of hunting life on the one hand and of farming life on the other, you can see that something stupendous took place . . . it was a breaking of one of nature’s bonds, the freeing of man from the limits of the natural supply of food.
...simple hunter-gatherers.. . . have a few crude ideas about conservation and some...exerted themselves in pious rites1 to make the game more plentiful. But that is wishful thinking; nature is in control, not they. Nature goads them about from spot to spot like howling monkeys, and there is nothing they can do about it. They cannot stockpile their food: when they have eaten, it is high time to start thinking about the next meal. Around any camp there are only so many wild animals and so many edible plants, because of the balance of nature. When these have been hunted or picked beyond a given point, the supply becomes too short and cannot recover, perhaps, for that season. What do the people in the camp do? They pick up and move on, to a place where the game is untouched. So this band must have enough territory to keep rebuilding the supply, it must preserve the supply against poachers, and it must move, move, move.

The answer is input i hope it ya
