Primes¶
- Green-Beard Effect
- The prime names a third mechanism of cooperation, distinct from kin selection (genome-wide relatedness) and reciprocal altruism (repeated interaction with memory).
This sourceFoundational theory of kin selection and inclusive fitness, the alternative relatedness-based mechanism the green-beard effect is distinguished from.

- Other-Regarding Preferences
- In evolutionary biology, kin selection values relatives' reproductive success at a coefficient given by relatedness, reciprocal altruism and eusocial cooperation instantiate the same structure with fitness as the preference function and a related or grouped agent as the "other," and the cross-argument weights are biological parameters with empirical values.
This sourceStates Hamilton's rule (rB > C): kin selection values relatives' fitness at the coefficient of relatedness.

- Solidarity
- W. D. Hamilton's (1964) rule — that an altruistic act is favored when the relatedness-weighted benefit to recipients exceeds the cost to the actor — supplies a substrate-level anchor for fate-sharing: cost borne in proportion to shared genetic stake.

Domain-specific¶
- Hamilton's Rule
- Kin selection
- The condition is formalised in Hamilton's rule: the allele is favoured by selection when rB > C, where r is the coefficient of genetic relatedness between actor and recipient — the probability, above chance, that a gene copy in the actor is identical by descent to a gene copy in the recipient — B is the fitness benefit to the recipient, and C is the fitness cost to the actor, both measured in units of offspring equivalents
This sourceA genetical model of social behaviour in which the coefficient of relationship r and a benefit-versus-cost comparison decide whether a costly social allele spreads.

“coefficient of relationship r (in a non-inbred population)”
- The condition is formalised in Hamilton's rule: the allele is favoured by selection when rB > C, where r is the coefficient of genetic relatedness between actor and recipient — the probability, above chance, that a gene copy in the actor is identical by descent to a gene copy in the recipient — B is the fitness benefit to the recipient, and C is the fitness cost to the actor, both measured in units of offspring equivalents
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 5 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.
