An evolutionary perspective on kin care directed up the generations

open access: yesScientific 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.

Algebra of Inclusive Fitness [PDF]

open access: yesEvolution, 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 ...

Sociogenetic Organization of the Red Honey Ant (Melophorus bagoti)

open access: yesInsects, 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

Cancer and intercellular cooperation [PDF]

open access: yesRoyal 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.

The strategic reference gene: an organismal theory of inclusive fitness. [PDF]

open access: yesProc Biol Sci, 2019
How to define and use the concept of inclusive fitness is a contentious topic in evolutionary theory. Inclusive fitness can be used to calculate selection on a focal gene, but it is also applied to whole organisms.

Kin selection theory and the design of cooperative crops

open access: yesEvolutionary 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.

Sibling Relations in Patchwork Families: Co-residence Is More Influential Than Genetic Relatedness

open access: yesFrontiers 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]

open access: yesBiol 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

What's wrong with inclusive fitness? [PDF]

open access: yes, 2006
In lieu of an abstract, here is the first paragraph: In a recent issue of TREE, Foster et al. [1] defend inclusive fitness theory [2] from recent challenges [3,4]. The main author of these challenges, E.O.

Funding: Natural Environment Research Council (NE/K009524/1) and European Research Council (771387).Proponents of the “Extended Evolutionary Synthesis” argue that the current state of evolutionary biology departs from what was established in Modern ...
