Primes¶
- Antifragility
- Evolutionary biology: Populations under fluctuating selection, frequent recombination, or environmental noise can evolve greater evolvability — the capacity to generate useful variation — so that the lineage's long-run fitness rises with the very environmental turbulence that culls individuals.
This sourceDefines evolvability as a lineage's capacity to generate heritable, selectable phenotypic variation; the basis for the claim that populations under fluctuating selection and recombination can raise long-run lineage fitness with the very turbulence that culls individuals.

Defines evolvability and tentatively suggests it was selected in lineages with frequent ecological upheavals, but never discusses fluctuating selection, recombination or noise raising long-run fitness.
“Perhaps evolvable mechanisms were further selected in clades exposed to frequent radiations.”

- Exaptation
- Kirschner and Gerhart (1998) formalize exactly this link between latent structural surplus and a system's capacity to generate viable novelty.
This sourceDefines evolvability as a lineage's capacity to generate heritable, useful phenotypic variation, linking latent structural surplus and flexible/redundant machinery to a system's capacity to produce viable novelty.

Kirschner and Gerhart argue that redundancy and weak linkage enable accumulation of nonlethal variation and thus evolvability, but as a conceptual review, not a formalization.
“The properties of versatile protein elements, weak linkage, compartmentation, redundancy, and exploratory behavior reduce the interdependence of components and confer robustness and flexibility on processes during embryonic development and in adult physiology. They also confer evolvability on the organism by reducing constraints on change and allowing the accumulation of nonlethal variation.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
