Resumen de Warfare helped stabilise early societies
Hodson talks about complex human society development. Like the computer game Civilisation, the model breaks the world into squares--or in this case the Eurasian continent--and characterizes them according to the type of land present. how mountainous it was, and if it was farmed. Every farmed square was inhabited by an independent group of humans, which could either be organized or not. Military technologies were seeded in squares close to the Eurasian steppe--where horses were first harnessed by humans--and gradually diffused outwards. The researchers ran the model between the years 1500 BC and AD 1500. When compared with historical records, it predicted where and when large empires would form and persist with 65% accuracy.
