Inclusive fitness and the major transitions in evolution [PDF]
Current Opinion in Insect Science, 2019 Inclusive fitness theory is the leading framework for explaining the major transitions in evolution, whereby free-living subunits (e.g. cells, organisms) have cooperated to form new, higher-level units (e.g. organisms, eusocial societies). The theory has attracted considerable controversy.

, 2016 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,

Religious celibacy brings inclusive fitness benefits. [PDF]
Proc Biol Sci, 2022 The influence of inclusive fitness interests on the evolution of human institutions remains unclear. Religious celibacy constitutes an especially puzzling institution, often deemed maladaptive.

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 selection ...

Male descendant kin promote conservative views on gender issues and conformity to traditional norms
Evolutionary Human Sciences, 2021 Political and social attitudes have been shown to differ by sex in a way that tracks individual self-interest. We propose that these attitudes also change strategically to serve the best interests of either male or female kin. To test this hypothesis, we

Evolutionary Influences on Assistance to Kin: Evidence from the Panel Study of Income Dynamics
Sociological Science, 2023 Amid the changes that have diversified family life, studies have shown the continuing importance of attachment to kin through established patterns such as ties among full siblings and newer patterns such as efforts by donor-conceived individuals to find ...

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 ...

Inclusive fitness is an indispensable approximation for understanding organismal design. [PDF]
Evolution, 2019 For some decades most biologists interested in design have agreed that natural selection leads to organisms acting as if they are maximizing a quantity known as “inclusive fitness.” This maximization principle has been criticized on the (uncontested ...

Monogamy promotes altruistic sterility in insect societies [PDF]
Royal Society Open Science, 2018 Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of altruism.

Relatedness, conflict, and the evolution of eusociality. [PDF]
PLoS Biology, 2015 The evolution of sterile worker castes in eusocial insects was a major problem in evolutionary theory until Hamilton developed a method called inclusive fitness.
