I finished Sapiens by Yuval Harari this week - an absolutely superb history of homo sapiens and the 3 revolutions that shaped it: Cognitive, Agricultural, and Scientific. Expect a big summary blog post soon.Most interesting note from it - shared myths that exist only in the minds of humans: gods, law, money, LLCs. These are the tools that allow humans to cooperate with strangers - something no other animal can do.Also, he notes that foragers were probably happier than modern people - due to more leisure time, days with known friends, and a more varied diet. Jared Diamond goes further and calls agriculture 'The Worst Mistake of Humankind'.
