Definition
Natural selection is differential survival and reproduction acting on heritable biological variation in an ecological context, without a predetermined goal. The books place it within historically constrained evolution rather than treating it as the sole source of organization. It must be distinguished from broader selective retention, neural selection and cross-scale analogies, which need not share its biological machinery.
Explanation
AB accepts variation and selective filtering while rejecting a picture of evolution as optimization toward a fixed target. In its presentation of Kauffman, spontaneous organization supplies candidates and selection stabilizes what works. RB1's Darwin discussion makes the mechanism non-teleological, and its synthesis retains heritable variation and differential reproduction while allowing disputes over drift, levels of selection and developmental constraints. Its wider functional-information proposal explicitly distinguishes biological evolution from selection processes in other domains.
RB2 uses natural selection as the comparison for Edelman's neuronal-group theory, but reports Crick's objection about replication and explicitly denies that neural selection is biological natural selection inside the skull. Its later account connects heredity and non-random selection to retention across generations without a monotonic ladder toward humanity. RB3 uses Riedl's flight example to couple selection with inherited structural constraints and attributes cognitive adaptation claims to Riedl following Lorenz. Its cross-scale discussion expressly preserves differences in mechanism. PB's general filtering language is therefore not promoted into an independently defined biological treatment.
Scope and attribution
AB, RB1, RB2 and RB3 own biological treatments. PB contributes contrasting general filtering language only. Selection is a context-local shortening, not an unrestricted alias across neural, physical or cultural processes.
AB — The Actual Book
Selection edits variation and stabilizes candidates without inventing all organization. Evolution follows contingent paths; outside biology selection is deliberately widened language.

PB — The Possible Book
Source-verified occurrence; see the printed-page references below.
Occurrence locators: 136.
RB1 — The Real Book, Volume I: The Possible Is Real
Selection acts non-teleologically on heritable variation. Differential reproduction remains central alongside developmental and ecological constraints; LIFI has broader scope.
Occurrence locators: 135, 144, 145, 146, 147, 149, 150, 151, 152, 153, 154, 155, 168, 174, 177, 196, 206, 213, 214, 217, 231, 239, 241, 242, 243, 245, 248, 262, 264, 267, 268, 280.
RB2 — The Real Book, Volume II: Becoming Is Being
Natural selection supplies the neural analogy but is explicitly not identical to neuronal selection. Heredity retains selected innovations without monotonic progress toward humanity.
Occurrence locators: 20, 21, 221, 269, 271.
RB3 — The Real Book, Volume III: Murmurations
Selection operates with inherited body-plan constraints in the Riedl flight example. Cognitive adaptation remains attributed; social and quantum analogies preserve differing machinery.
Occurrence locators: 51, 58, 64, 68, 92, 93, 96, 100, 121, 123, 124.
Background used in the editorial explanation
Domain-specific mechanisms and wider analogies remain distinguished. Original definitions retain their scope; local cross-references do not rewrite them. Named theories and mechanisms are distinguished from neighboring background, homonyms and the author’s own synthesis. Reproduced AI passages retain their separate voice.
