> ..research at Kirikongo has revealed a dynamic socio-political sequence, with the development of #InstitutionalizedInequalities over the course of the 1st millennium CE, followed by an egalitarian revolution in the early 2nd millennium CE. The consequent social formation, despite being structurally egalitarian was actually more complex than the vertically oriented system that preceded it, and calls into question common assumptions of directionality in socio-political evolution. #StephenDueppen
> Kirikongo’s chickens are currently the earliest known in #SubSaharanAfrica, and I have argued that chickens are of greater relative importance in egalitarian political systems since they are less likely than other domestic animals to be a symbol of inequality. These results are featured in the 2014 popular science book Why Did the Chicken Cross the World: The Epic Saga of the Bird that Powers Civilization by #AndrewLawler
