I’ve been recently learning from a very well researched tome that the reasons for the discrepancy in the development of civilizations, over time, around the world, was, contrary to popular opinion, the result of factors that had little or nothing to do with human capabilities.
The so-called cradle of civilization, the fertile crescent in the near east which was the location of the earliest known significant civil progress had the benefits of a variety of domestic-able food plants and large animals which provided the means to create sedentary communities able to diversify energies toward technological developments: a considerable head-start on the rest of the world.
So called backward peoples like the Australian Aborigines remained hunter/ gatherers into modern times because, to a great extent, the lands they occupy don’t accommodate farming and the indigenous fauna isn’t domestic-able. The knowledge these people have acquired, though, makes it possible for them to thrive in an exceedingly harsh environment.
It would appear that humankind has survived to this point in time through a common intelligence and adaptability. Now, if we can all just recognize our mutual worth perhaps we can survive a bit longer.
