The causal meaning of Hamilton’s rule [PDF]
Hamilton’s original derivation of his rule for the spread of an altruistic gene (rb>c) assumed additivity of costs and benefits. Recently, it has been argued that an exact version of the rule holds under non-additive pay-offs, so long as the cost and ...

A quantitative test of Hamilton's rule for the evolution of altruism. [PDF]
The evolution of altruism is a fundamental and enduring puzzle in biology. In a seminal paper Hamilton showed that altruism can be selected for when rb - c > 0, where c is the fitness cost to the altruist, b is the fitness benefit to the beneficiary, and

Cooperation and Hamilton's rule in a simple synthetic microbial system [PDF]
A fundamental problem in biology is understanding the evolutionary emergence and maintenance of altruistic behaviors. A well‐recognized conceptual insight is provided by a general mathematical relation, Hamilton's rule.

Can Hamilton’s rule be violated? [PDF]
How generally Hamilton’s rule holds is a much debated question. The answer to that question depends on how costs and benefits are defined. When using the regression method to define costs and benefits, there is no scope for violations of Hamilton’s rule.

The general version of Hamilton’s rule [PDF]
The generality of Hamilton’s rule is much debated. In this paper, I show that this debate can be resolved by constructing a general version of Hamilton’s rule, which allows for a large variety of ways in which the fitness of an individual can depend on ...

Assortment, Hamilton's rule and multilevel selection. [PDF]
Explaining the evolution of cooperation has been under debate for a long time (reviewed in [Frank 1998][1]; [Lehmann & Keller 2006][2]). Cooperative traits impose a cost on the individual exhibiting the trait to the benefit of other individuals.

Hamilton's rule and the causes of social evolution. [PDF]
Hamilton's rule is a central theorem of inclusive fitness (kin selection) theory and predicts that social behaviour evolves under specific combinations of relatedness, benefit and cost. This review provides evidence for Hamilton's rule by presenting novel syntheses of results from two kinds of study in diverse taxa, including cooperatively breeding ...

Hamilton's rule in economic decision-making. [PDF]
Significance Kin selection—helping genetically related individuals even at a cost to oneself—can be evolutionarily advantageous. This is the main theoretical explanation for altruism in the natural world. Hamilton’s rule provides a simple algebraic relationship that captures this profound idea.

Limits of Hamilton's rule [PDF]
The evolution of cooperation is a fundamental problem in evolutionary biology. Over the last decades a wealth of models and mechanisms have been proposed for explaining how cooperators can thrive under Darwinian selection. At the same time, discussions of the conceptual connections between the different approaches have often been neglected.
