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 ...

Cancer and intercellular cooperation [PDF]
Royal Society Open Science, 2017 The major transitions approach in evolutionary biology has shown that the intercellular cooperation that characterizes multicellular organisms would never have emerged without some kind of multilevel selection.

Kin selection theory and the design of cooperative crops
Evolutionary Applications, 2022 In agriculture and plant breeding, plant traits may be favoured because they benefit neighbouring plants and ultimately increase total crop yield. This idea of promoting cooperation among crop plants has existed almost as long as W.D.

Queller’s separation condition explained and defended [PDF]
, 2014 The theories of inclusive fitness and multilevel selection provide alternative perspectives on social evolution. The question of whether these perspectives are of equal generality remains a divisive issue.

Sibling Relations in Patchwork Families: Co-residence Is More Influential Than Genetic Relatedness
Frontiers in Psychology, 2020 In “patchwork” families, full siblings, maternal and paternal half-siblings, and non-related children are raised together, and sometimes, genetically related children are separated.

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

Hamilton's rule, inclusive fitness maximization, and the goal of individual behaviour in symmetric two-player games [PDF]
, 2016 Hamilton's original work on inclusive fitness theory assumed additivity of costs and benefits. Recently, it has been argued that an exact version of Hamilton's rule for the spread of a pro-social allele (rb > c) holds under nonadditive pay-offs, so ...

What is inclusive fitness theory, and what is it for? [PDF]
, 2016 Inclusive fitness theory is a cornerstone of modern evolutionary biology, yet critics contend it is not general but subject to serious limitations, and is ripe for replacement, for example by multilevel selection theory.
