Inclusive fitness as a criterion for improvement [PDF]

open access: yesStudies in History and Philosophy of Science Part C:Studies in History and Philosophy of Biological and Biomedical Sciences, 2019
I distinguish two roles for a fitness concept in the context of explaining cumulative adaptive evolution: fitness as a predictor of gene frequency change, and fitness as a criterion for phenotypic improvement. Critics of inclusive fitness argue, correctly, that it is not an ideal fitness concept for the purpose of predicting gene-frequency change ...

Invasion fitness, inclusive fitness, and reproductive numbers in heterogeneous populations [PDF]

open access: yesEvolution; International Journal of Organic Evolution, 2016
How should fitness be measured to determine which phenotype or "strategy" is uninvadable when evolution occurs in subdivided populations subject to local demographic and environmental heterogeneity? Several invasion fitness measures, such as basic reproductive number, lifetime dispersal success of a local lineage, or inclusive fitness have been ...

Inclusive fitness maximization: An axiomatic approach [PDF]

open access: yesJournal of Theoretical Biology, 2014
Kin selection theorists argue that evolution in social contexts will lead organisms to behave as if maximizing their inclusive, as opposed to personal, fitness. The inclusive fitness concept allows biologists to treat organisms as akin to rational agents seeking to maximize a utility function. Here we develop this idea and place it on a firm footing by

How (not) to review papers on inclusive fitness

open access: yesTrends in Ecology and Evolution, 2015
Evolutionary fitness of traits or behaviors is inclusive [1] of their ‘direct’ effects on the trait bearers’ reproduction and their ‘indirect’ effects on others’ reproduction (Figure 1). Inclusive fitness models lay bare that traits can be selectively advantageous even when they negatively impact direct fitness.

An inclusive fitness analysis of altruism on a cyclical network

open access: yesJournal of Evolutionary Biology, 2007
A recent model studies the evolution of cooperation on a network, and concludes with a result connecting the benefits and costs of interactions and the number of neighbours.

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.

Relatedness and inclusive fitness with inbreeding

Theoretical Population Biology, 1992
Relatedness arising in kin selection theory is measured by a variable taking as values two pedigree indices in populations with inbreeding when selection is weak. This variable reduces to a single pedigree index when inbreeding is caused by partial selfing or partial sib-mating.

Inclusive fitness in evolution

Nature, 2011
Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson , 1057–1062 (2010)10.1038/nature09205 ; Nowak et al. reply For over fifty years, the evolution of social behaviour has been guided by the concept of inclusive fitness as a measure of ...

How to measure inclusive fitness

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1990
Although inclusive fitness (Hamilton 1964) is regarded as the basic currency of natural selection, difficulty in applying inclusive fitness theory to field studies persists, a quarter-century after its introduction (Grafen 1982, 1984; Brown 1987). For instance, strict application of the original (and currently accepted) definition of inclusive fitness ...

A reconciliation of inclusive fitness and personal fitness approaches: A proposed correcting term for the inclusive fitness formula

Journal of Theoretical Biology, 1979
Abstract Hamilton implicitly defined the inclusive fitness of an individual as the number of genomes, identical by descent to its own, but not in its own body, which owe their existence to expression of genes in said individual. Hamilton regarded inclusive fitness as the true metric of evolutionary success and the thin- maximized by selection ...
