, 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

Do Relatives With Greater Reproductive Potential Get Help First?: A Test of the Inclusive Fitness Explanation of Kin Altruism [PDF]
Evolutionary Psychology, 2019 According to inclusive fitness theory, people are more willing to help those they are genetically related to because relatives share a kin altruism gene and are able to pass it along.

What happens after inbreeding avoidance? Inbreeding by rejected relatives and the inclusive fitness benefit of inbreeding avoidance. [PDF]
PLoS ONE, 2015 Avoiding inbreeding, and therefore avoiding inbreeding depression in offspring fitness, is widely assumed to be adaptive in systems with biparental reproduction.

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. Here, we present sociodemographic data from an agropastoralist Buddhist population in western China, where parents sometimes sent a son to the monastery.

Inclusive fitness for in-laws. [PDF]
Biol Lett, 2018 Cooperation among kin is common across the natural world and can be explained in terms of inclusive fitness theory, which holds that individuals can derive indirect fitness benefits from aiding genetically related individuals. However, human kinship includes not only genetic kin but also kin by marriage: our affines (in-laws) and spouses ...

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 ...

Inclusive fitness in agriculture. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2014 Trade-offs between individual fitness and the collective performance of crop and below-ground symbiont communities are common in agriculture. Plant competitiveness for light and soil resources is key to individual fitness, but higher investments in stems and roots by a plant community to compete for those resources ultimately reduce crop yields ...

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 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
