Hamilton's rule applied to reciprocal altruism

open access: closedProceedings of the 2004 Congress on Evolutionary Computation (IEEE Cat. No.04TH8753), 2004
Reciprocal 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

Hamilton's rule in multi-level selection models

open access: closedJournal of Theoretical Biology, 2011
Hamilton'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

Journal of Theoretical Biology, 2017
This paper reviews and addresses a variety of issues relating to inclusive fitness. The main question is: are there limits to the generality of inclusive fitness, and if so, what are the perimeters of the domain within which inclusive fitness works? This question is addressed using two well-known tools from evolutionary theory: the replicator dynamics,

Inclusive fitness and Hamilton’s rule in a stochastic environment

Theoretical Population Biology, 2021
The evolution of cooperation in Prisoner's Dilemmas with additive random cost and benefit for cooperation cannot be accounted for by Hamilton's rule based on mean effects transferred from recipients to donors weighted by coefficients of relatedness, which defines inclusive fitness in a constant environment.

Hamilton's rule and conditionality

Ethology Ecology & Evolution, 1989
Hamilton's rule is that an altruistic act shoud be performed when r times the benefit to a recipient is greater than the cost to the donor, where r is a measure of the extent of genetic similarity at the locus determining the action. This rule applies when the action is conditional upon role.
