Two very clear indicators are the appearance of lavishly furnished burials and large, elaborate private residences. Skeletons can tell us that one segment of population ate much higher-quality foods and enjoyed better health than the rest. Based on such indicators, we know that large differentials between the rich and powerful few and the rest arose within a few thousand years of agriculture in Mesopotamia, Egypt, China, Mexico, and the Andes. Somehow a segment of society succeeded in manipulating itself into a position of superiority in these regions; this is a fact accepted by all archaeologists.
