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.

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.

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.

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.

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.
