“Why, of all the species that have ever existed, have only us humans reached this unparalleled level of social organisation?” Sounds familiar? I indeed opened my review of E.O. Wilson’s recent book Genesis: On the Deep Origin of Societies with almost these exact words. Where that book (quite literally) fell a bit short of the intended mark, biologist Mark W. Moffett here delivers a sprawling big history book that considers almost the same question. Perhaps this should not come as a surprise, for Wilson has been Moffett’s mentor.
