Hamilton's rule, inclusive fitness maximization, and the goal of individual behaviour in symmetric two‐player games [PDF]
, 2015 Hamilton's original work on inclusive fitness theory assumed additivity of costs and benefits. Recently, it has been argued that an exact version of Hamilton's rule for the spread of a pro-social allele (rb > c) holds under nonadditive pay-offs, so ...

Variation in helper effort among cooperatively breeding bird species is consistent with Hamilton’s Rule [PDF]
Nature Communications, 2016 Non-parental helpers contribute to offspring care in many species; however, the amount of care provided varies considerably across species. Here, Green et al.

Generalisations of Hamilton's Rule Applied to Non-Additive Public Goods Games with Random Group Size [PDF]
Frontiers in Ecology and Evolution, 2014 Inclusive fitness theory has been described as being limited to certain special cases of social evolution. In particular some authors argue that the theory can only be applied to social interactions having additive fitness effects, and involving only ...

The group selection–inclusive fitness equivalence claim: not true and not relevant [PDF]
Evolutionary Human Sciences, 2020 The debate on (cultural) group selection regularly suffers from an inclusive fitness overdose. The classical view is that all group selection is kin selection, and that Hamilton's rule works for all models.

Survival cost sharing among altruistic full siblings in Mendelian population [PDF]
BMC Ecology and EvolutionBackground We focus on Haldane’s familial selection in monogamous families in a diploid population, where the survival probability of each sibling is determined by altruistic food sharing with its siblings during starvation.

Hamilton's rule predicts anticipated social support in humans [PDF]
Behavioral Ecology, 2014 Hamilton’s rule predicts that individuals should be more likely to altruistically help closer kin and this theory is well supported from zoological studies of nonhumans. In contrast, there is a paucity of relevant human data. This is largely due to the difficulties of either experimentally testing relatives or of collecting data on genuinely costly ...

Altruism can proliferate through population viscosity despite high random gene flow. [PDF]
PLoS ONE, 2013 The ways in which natural selection can allow the proliferation of cooperative behavior have long been seen as a central problem in evolutionary biology. Most of the literature has focused on interactions between pairs of individuals and on linear public

A generalization of Hamilton's rule for the evolution of microbial cooperation. [PDF]
Science, 2010 Breaking Hamilton's Rule Hamilton's rule states that the evolution of cooperation is correlated with the kin relationship between the actor and the recipient and the degree of the benefit. However, this approximation relies on several steps of simplification that are often violated in natural systems.
