> I find it reasonable to assume that any civilization will gradually adapt to meet demands, given whichever constraints burden it
So your theory is that civilizations are the way they are because of exogenous rather than endogenous factors? That seems difficult to reconcile with the historical record. Your viewpoint just begs the question. For example, why was Europe in a position to colonize the Americas in the first place? Why weren’t the Spanish greeted by Aztecs with swords and guns?
In the long term, I think civilizations grow along the lines of natural selection. They are neither optimal nor pessimal, but are likely to display a high degree of fitness. Environmental shocks in the short term will challenge fitness. Competition among civilizations also challenges fitness.
Why indeed was Europe technologically advanced? Why were the Americas not so much? Resources are one factor, which is why obtaining resources from other lands is valuable. But the main impetus for advancement surely isn't based on one's "skill in advancing". Most people could be trained to fix cars, if desired. Also, Rome fell, but people now live where Rome was with far greater technology. I posit that, if the indigenous peoples of the Americas were given the desire to advance to the level of Europeans, the resources to do so, and time, similar advancement would arise.
