Optimization of inclusive fitness
Journal of Theoretical Biology, 2006 The first fully explicit argument is given that broadly supports a widespread belief among whole-organism biologists that natural selection tends to lead to organisms acting as if maximizing their inclusive fitness. The use of optimization programs permits a clear statement of what this belief should be understood to mean, in contradistinction to the ...

Inclusive fitness as a criterion for improvement [PDF]
Studies 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]
Evolution; 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 ...

Adaptation and Inclusive Fitness [PDF]
Current Biology, 2013 Inclusive fitness theory captures how individuals can influence the transmission of their genes to future generations by influencing either their own reproductive success or that of related individuals. This framework is frequently used for studying the way in which natural selection leads to organisms being adapted to their environments.

Limitations of inclusive fitness. [PDF]
Proc Natl Acad Sci U S A, 2013 Significance Inclusive fitness theory is the idea that the evolutionary success of a trait can be calculated as a sum of fitness effects multiplied by relatedness coefficients. Despite recent mathematical analyses demonstrating the limitations of this approach, its adherents claim that it is as general as the theory of natural ...

A new metric of inclusive fitness predicts the human mortality profile. [PDF]
PLoS ONE, 2015 Biological species have evolved characteristic patterns of age-specific mortality across their life spans. If these mortality profiles are shaped by natural selection they should reflect underlying variation in the fitness effect of mortality with age ...

Inclusive fitness maximization: An axiomatic approach [PDF]
Journal 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

The group selection–inclusive fitness equivalence claim: not true and not relevant [PDF]
Evolutionary Human Sciences, 2020 The debate on (cultural) group selection regularly suffers from an inclusive fitness overdose. The classical view is that all group selection is kin selection, and that Hamilton's rule works for all models.

Hamiltonian inclusive fitness: a fitter fitness concept [PDF]
Biology Letters, 2013 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

Long reach of inclusive fitness. [PDF]
Proc Natl Acad Sci U S A, 2017 Inclusive fitness theory is one of the central paradigms of behavioral ecology (1, 2). Initially developed to explain the effect of genetic relatedness on prosocial behaviors such as altruism and cooperation, the power of inclusive fitness thinking became even more evident when modifications to the original models were applied to such behavioral ...
