Inclusive Fitness and Hamilton’s Rule
2021This chapter evaluates the long and intimate association between the gene’s-eye view and the work of W.D. Hamilton. Hamilton’s key insight was that individual organisms can affect the transmission of their genes through personal reproductive success, as well as through the success of close relatives.

Hamilton's rule in multi-level selection models
Journal of Theoretical Biology, 2012Hamilton's rule is regarded as a useful tool in the understanding of social evolution, but it relies on restrictive, overly simple assumptions. Here we model more realistic situations, in which the traditional Hamilton's rule generally fails to predict the direction of selection.

Hamilton's rule applied to reciprocal altruism
Proceedings of the 2004 Congress on Evolutionary Computation (IEEE Cat. No.04TH8753), 2004Reciprocal altruism and inclusive fitness are generally considered alternative mechanisms by which cooperative, altruistic traits may evolve. Here we demonstrate that very general versions of Hamilton's inclusive fitness rule (developed by Queller) can be applied to traditional reciprocal altruism models such as the iterated prisoner's dilemma. In this

Inclusive Fitness and Hamilton’s Rule
2015This chapter examines how the logic of inclusive fitness theory can be mathematically formalized using the Price equation, and how that formalization can be used to derive Hamilton's rule in its simplest form, as applied to unconditional behaviors having additive effects on fitness.

A generalization of Hamilton's rule—Love others how much?
Journal of Theoretical Biology, 2012According to Hamilton's (1964a, b) rule, a costly action will be undertaken if its fitness cost to the actor falls short of the discounted benefit to the recipient, where the discount factor is Wright's index of relatedness between the two. We propose a generalization of this rule, and show that if evolution operates at the level of behavior rules ...

Nonadditive Interactions and Hamilton’s Rule
2015This chapter examines what happens in nonadditive interactions when such interactions take place between relatives, and how Hamilton's rule can be extended in two different ways to accommodate such nonadditivity. It first considers the selective pressures on nonadditive behaviors directed towards relatives by making use of the replicator dynamics to ...

Hamilton’s Rule as an Organizing Framework
2017Queller’s version of Hamilton’s rule (HRG), derived from the Price equation, states that the mean breeding value for a social character increases if and only if rb > c, where r is the coefficient of relatedness between social partners, b is the benefit conferred on recipients, and c is the cost incurred by actors.
