Kin selection explains the evolution of cooperation in the gut microbiota. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance This is a comparative study attempting to explain the pattern of cooperation across a number of microbial species. Hamilton’s inclusive-fitness theory makes the very general prediction that increased genetic relatedness should drive the ...

Need for Alloparental Care and Attitudes Toward Homosexuals in 58 Countries: Implications for the Kin Selection Hypothesis [PDF]
, 2017 Homosexuality is an evolutionary puzzle. Many theories attempt to explain how a trait undermining individual reproduction can be maintained, but experimental testing of their predictions remains scarce.

Blood is not always thicker than water: The limited effect of kin selection on human kinship in the traditional Chinese family [PDF]
Current Zoology, 2010 To examine the importance of kin selection in shaping human societies, this study analyzed the kinship system practiced in traditional China for two millennia and teased apart its underlying genetic and other, presumably cultural, components. The results

Death happy: adaptive ageing and its evolution by kin selection in organisms with colonial ecology. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2021 Standard evolutionary theory, supported by mathematical modelling of outbred, dispersed populations predicts that ageing is not an adaptation. We recently argued that in clonal, viscous populations, programmed organismal death could promote fitness ...

Effects of soil fertility and toxicity on the performance of Chenopodium quinoa (Willd) plants in kin and non-kin interactions [PDF]
Plant Signaling & BehaviorKin selection theory predicts that closely related organisms may exhibit cooperative behaviors that enhance group fitness despite individual costs. In contrast, the resource partitioning hypothesis posits stronger competition among close relatives due to

Encyclopedia of Evolutionary Psychological Science, 2020 A foundational component of social evolution theory and a broader view of natural selection where fitness effects on genetic relatives are explicitly accounted for. Kin selection is particularly well known as an explanation for the evolution of altruism: a trait that is costly to its bearer can spread in a population if it has beneficial effects on ...

Clonemate cotransmission supports a role for kin selection in a puppeteer parasite. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance The lancet fluke Dicrocoelium dendriticum can precisely manipulate its ant host to facilitate transmission to its ungulate host. However, the sole parasite manipulator in the ant brain is presumed not infective to its next host whereas the ...

Genetic Relatedness Promotes Equal Contributions of Males and Females to Brood Care in a Biparental Cichlid Fish [PDF]
Ecology and EvolutionKin discrimination, that is, the differential treatment of kin and nonkin has been studied in a wide range of social contexts because kin selection theory predicts that genetic relatedness among interacting individuals can reduce conflicts and promote ...
