Explaining the Rise of Complex Societies in Human History: A Cultural Evolution Approach
What are the social forces that hold together complex societies encompassing hundreds of millions of people? How did human ultrasociality – extensive cooperation among large numbers of unrelated individuals – evolve? The theory of cultural multilevel selection is a powerful theoretical framework for addressing these questions. I use this framework to investigate a major transition in human social evolution, from small-scale egalitarian groups to large-scale hierarchical societies such as states and empires. A key mathematical result in the theory is that large states should arise in regions where interpolity competition – warfare – is particularly intense, resulting in high probability of cultural trait extinction. In my talk I will describe how this theory fares when tested empirically against alternatives, using Seshat: Global History Databank.
