Invariant: 3.12 Selection / variation-retention (universal Darwinism)

3.12 Selection / variation-retention (universal Darwinism)

Vary, select, retain — anywhere those three exist, design accumulates with no designer. Sources: Darwin, Wallace; Price equation (the algebra of any selection); Dawkins (replicators); Campbell (evolutionary epistemology); Edelman (neural Darwinism). Domains: biology, immune system, brain, culture (memetics — T2), markets, ML (evolutionary search; arguably SGD). Dual: directed/Lamarckian design, or pure drift. Tier: T1 (bio), T2 (culture). Falsifier: cumulative adaptation with no variation or no differential retention. Maps: A₁, A₃, the "self-copies" rung.
