They were probably very skilled at this kind of thinking, more than and I. You have to emphasize with an animal to track it, for example. Even non human hunters have such intuitions. A wildcat knows when a squirrel is likely to head for the nearest tree. By the time such structures were being built, coralling using simpler or natural terrain features was probably an important hunting method. Imo the notable part here is the scale and it's implications. Large groups. Long term projects. Long lived assets. A progressive mindset, where the "economy" and roles within it change. That's not, seemingly, the default.
