Nomadic people have to move and follow the game. They don't have time to stay in one spot and construct enormous stone walls in order to funnel the quarry to a killing spot.
On the other hand, sedentary people engaging in agriculture can stay in one spot and build walls for a variety of purposes. But such people tend to have herds of domesticated animals which can provide fresh meat and therefore probably don't have any need to construct enormous stone walls in order to funnel the quarry to a killing spot.
I just don't see who would want to, need to, or be able to do what this article seems to be suggesting.
It's a fair question. As I understand it, the Nomadic people we have in the world today move to new patches of grazing for their herds. They don't do so to follow game.
I think you are correct. My husband has erected barbed wire fences to funnel his cattle toward the cattle pens in the same way.
The animals may have been only semi-domesticated because you could not concentrate them in one area due to lack of forage.
The key to success in hunting is not in being able to follow game, but in being able to predict where game will be at some point in the future and already be waiting there.
These traps were in the path of animals' yearly migrations. So it would have been worthwhile to build it and keep adding to it year after year.
Even Nomadic peoples had to have a way to kill their game. They desired to do so as safely and efficiently as possible. These “kites” are along the normal routes herds of these animals would take. The nomadic people follow the herds, year after year along the same routes. Picture they ran them into the chasm’s without the walls initially, getting a few animals because most would run away to the sides. Then someone comes up with the idea of funneling them, they would have started nearer the chasm and probably over some time work their way out. Perhaps over decades in time. So, a few hundred yards of walls only little more than three feet high, sure it is believable.
