In the new book by David Graeber and David Wengrow, they do much more than champion early egalitarian societies. They point out that early societies did not march lock-step from hunter-gathering, to horticulture, to agricultural states in a one-at-a-time manner. Rather, they rotated hunting, gathering, horticulture and herding at different times of the year. At the same time, they used authority structures during certain seasons but were then able to disband them.
