Definition
Cultural evolution is the variation, transmission and selective retention of ideas, practices and techniques through learning and symbolic communication rather than genetic inheritance alone. It proceeds alongside biological evolution, often much faster, while remaining materially embodied. Cultural inheritance makes acquired innovations available beyond individual lives; neither conscious design nor inevitable improvement defines the whole process.
Explanation
AB describes ideas and techniques spreading through speech and writing and later emphasizes teaching, archives and continued use as means of retention. RB1 compares ideas with genes, credits Dawkins for memes, and calls the transmission of acquired innovations culture's “Lamarckian” aspect. These are comparisons and local descriptions, not an identification of cultural with genetic inheritance. Its discussion of Henrich makes socially learned biases, rather than individual understanding alone, central to selective transmission.
RB2 stresses preserved inventions, norms and archives but immediately denies inevitable progress: civilizations can forget techniques. RB3 presents cultural variation-selection as a faster development incorporating older evolutionary patterns, while distinguishing formal similarities from identical mechanisms. PB's reviewed ancestral-memory passage concerns genes, not socially transmitted innovations, so it does not warrant a cultural-evolution treatment.
Scope and attribution
Positive book treatments belong to AB, RB1, RB2 and RB3. Cultural inheritance names the transmission dimension, and the Lamarckian wording names acquired-innovation transmission locally; neither is installed as an unrestricted synonym. The separately identified cumulative and self-aware cultural-evolution concepts are not merged.
AB — The Actual Book
Ideas and techniques vary and spread through speech and writing. Teaching, archives and living use preserve innovations beyond individual lifetimes; broken transmission threatens this inheritance.
Occurrence locators: 50, 61, 62, 63.
RB1 — The Real Book, Volume I: The Possible Is Real
Culture is a faster evolutionary substrate with conscious minds involved but not wholly governed by deliberate design. Symbolic systems remain materially constrained. Henrich's socially learned selective filters explain retention without requiring each individual to understand what is preserved.
Occurrence locators: 147, 150, 151, 166, 178, 179, 180, 181, 182, 185, 186, 193, 195, 217, 230, 231, 232, 233, 234, 235, 236, 237, 238, 240, 243, 244, 247, 248, 249, 250, 259, 264, 265, 279.
RB2 — The Real Book, Volume II: Becoming Is Being
Recorded and transmitted concepts, tools, norms and archives enable cumulative cultural complexity. The surrounding qualification denies inevitable progress and explicitly allows the loss of techniques.
Occurrence locators: 222, 223, 225, 246, 271, 272, 273.
RB3 — The Real Book, Volume III: Murmurations
Cultural variation-selection is presented as faster and idea-based, developing from rather than simply replacing biological evolution. Cross-domain equivalence is formal, not an assertion that words and alleles share a substance or mechanism.
Occurrence locators: 63, 64, 81, 82, 83, 84, 85, 86, 87, 88, 89, 92, 96, 97, 98, 104, 121.
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.
