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

Hamiltonian inclusive fitness: a fitter fitness concept. [PDF]
Biol Lett, 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

Sex investment ratios in eusocial Hymenoptera support inclusive fitness theory [PDF]
, 2015 Inclusive fitness theory predicts that sex investment ratios in eusocial Hymenoptera are a function of the relatedness asymmetry (relative relatedness to females and males) of the individuals controlling sex allocation. In monogynous ants (with one queen

Algebra of Inclusive Fitness [PDF]
Evolution, 1981 is couched in terms of genes identical by descent (i. b. d.). The coefficient r (Wright's coefficient of relationship) measures the expected fraction of genes i.b.d. in each recipient as viewed from the donor when neither individual is inbred. An altruist suffers a cost in fitness c while donating a total benefit b, which is distributed evenly among ...
