Darwinian evolution needs three ingredients: reproduction (universes beget universes), heritable variation (offspring inherit slightly changed parameters), and selection (differential success). This atlas scores every proposed evolutionary cosmology against that triad.
The ingredient map places each theory in a three-circle diagram — only the center holds all three. Badges flag the honest edge cases: variation without inheritance, inheritance without variation, quasi-selection. The timeline traces descent, borrowed mechanisms, and critiques across a century.
