Hamiltonian inclusive fitness: a fitter fitness concept.
In 1963-1964 W. D. Hamilton introduced the concept of inclusive fitness, the only significant elaboration of Darwinian fitness since the nineteenth century. I discuss the origin of the modern fitness concept, providing context for Hamilton's discovery of inclusive fitness in relation to the puzzle of altruism. While fitness conceptually originates with Darwin, the term itself stems from Spencer...
متن کاملMating frequency and inclusive fitness in Drosophila melanogaster.
In many species, increased mating frequency reduces maternal survival and reproduction. In order to understand the evolution of mating frequency, we need to determine the consequences of increased mating frequency for offspring. We conducted an experiment in Drosophila melanogaster in which we manipulated the mating frequency of mothers and examined the survival and fecundity of the mothers and...
متن کاملUnifying the theories of inclusive fitness and reciprocal altruism.
Inclusive fitness and reciprocal altruism are widely thought to be distinct explanations for how altruism evolves. Here we show that they rely on the same underlying mechanism. We demonstrate this commonality by applying Hamilton's rule, normally associated with inclusive fitness, to two simple models of reciprocal altruism: one, an iterated prisoner's dilemma model with conditional behavior; t...
متن کاملHamilton goes empirical: estimation of inclusive fitness from life-history data.
Hamilton's theory of kin selection is one of the most important advances in evolutionary biology since Darwin. Central to the kin-selection theory is the concept of inclusive fitness. However, despite the importance of inclusive fitness in evolutionary theory, empirical estimation of inclusive fitness has remained an elusive task. Using the concept of individual fitness, I present a method for ...
متن کاملInclusive Fitness in Evolutionary Modelling
The notion of Darwinian fitness allows us to understand how natural selection influences the evolution of organismal traits. For example, we might explain a plant’s morphology, or a bird’s behaviour in terms of the fitness advantages (reproductive or survival benefits) such morphology or behaviour confers. The notion of inclusive fitness is used specifically to understand how selection will act...
