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.

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

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.

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 ...

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.

An evolutionary perspective on kin care directed up the generations
Scientific Reports, 2021 Within evolutionary sciences, care towards younger kin is well understood from an inclusive fitness framework, but why adults would care for older relatives has been less well researched.

Fitness, inclusive fitness, and optimization [PDF]
Biology & Philosophy, 2014 Individual-as-maximizing agent analogies result in a simple understanding of the functioning of the biological world. Identifying the conditions under which individuals can be regarded as fitness maximizing agents is thus of considerable interest to biologists.

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

Sociogenetic Organization of the Red Honey Ant (Melophorus bagoti)
Insects, 2020 Kin selection and inclusive fitness are thought to be key factors explaining the reproductive altruism displayed by workers in eusocial insect species. However, when a colony’s queen has mated with
