Convergence Encyclopedia: C09 — Selection / Variation-Retention (Universal Darwinism)

F1 — Tier. T1 (biological evolution — established); T2 (extension to culture, cognition, markets — contested). Uncertainty flag: “Universal Darwinism” as a claim about all complex adaptive systems is T2; natural selection in biology is T1.

F3 — Domains. Biology (evolution), immunology (clonal selection), neuroscience (neural Darwinism), culture (memetics — T2), markets (economic selection), machine learning (stochastic gradient descent as selection).

F4 — Scale. Viral quasispecies (~10⁻⁸ m) → biosphere (~10⁷ m); cultural evolution (decades → millennia).

F5 — Falsifier. Adaptation without variation or without differential retention — a system that produces fit structures without either random generation of alternatives or selective preservation of better-performing variants. Lamarckian inheritance (if demonstrated) would partially falsify the Darwinian mechanism as exclusive.

F6 — Rival (strongest form). Selection is a statistical filter, not a force. “Universal Darwinism” is metaphorical extension — the formal similarity between biological evolution and, say, market dynamics or SGD is superficial. What looks like “selection” in non-biological domains is actually optimization (gradient descent), diffusion, or drift. The Price equation (1970) formalizes selection algebraically, but its applicability requires defining “fitness” and “heritability” in ways that may be question-begging outside biology. (Gould & Lewontin 1979 “spandrels” critique; Walsh 2018 Nature 559:189 on drift vs. selection.)

F7 — Independence. HIGH. Darwin & Wallace (natural history, 1850s), Price (mathematics, 1970 — developed the formalism independently of biology training), Dawkins (zoology/ ethology, Oxford, 1976), Campbell (psychology, Northwestern, 1960), Edelman (immunology/ neuroscience, Rockefeller, 1987) — five independent research programs, no shared institutional lineage. Campbell’s evolutionary epistemology (1960) predates Dawkins; Price’s equation (1970) was developed without biological training.

F8 — Pattern type. Biological.

F9 — Maps. A1 (foundational structure), A3 (pattern-dynamics).
