Humans domesticated fire, landscapes, water, plants, animals, metal, labor, information, belief, violence—and one another. Each system expanded what societies could coordinate. Each also created new dependencies and new ways to fail.
This is not a neutral encyclopedia. It is a source-traceable argument told through maps, timelines, models, and comparisons. Where the evidence is fragmentary, the uncertainty belongs in the explanation.
The atlas
Pages are published as their evidence and visuals become strong enough. Draft pages contain live, auditable work; research pages show the committed sequence.
