Ecological Drivers of Non-kin Cooperation in the Hymenoptera

open access: yesFrontiers in Ecology and Evolution, 2022
Despite the prominence of kin selection as a framework for understanding the evolution of sociality, many animal groups are comprised of unrelated individuals.

Socially Enforced Nepotism: How Norms and Reputation Can Amplify Kin Altruism. [PDF]

open access: yesPLoS ONE, 2016
Kin selection, which can lead organisms to behave altruistically to their genetic relatives, works differently when-as is often the case in human societies-altruism can be boosted by social pressure.

Non-kin Cooperation in Ants

open access: yesFrontiers in Ecology and Evolution, 2021
Eusociality represents an extreme form of social behavior characterized by a reproductive division of labor. Eusociality necessarily evolved through kin selection, which requires interactions among related individuals.

The group selection–inclusive fitness equivalence claim: not true and not relevant

open access: yesEvolutionary Human Sciences, 2020
The debate on (cultural) group selection regularly suffers from an inclusive fitness overdose. The classical view is that all group selection is kin selection, and that Hamilton's rule works for all models.

Selfish or altruistic? An analysis of alarm call function in wild capuchin monkeys, Cebus apella nigritus [PDF]

open access: yes, 2008
Alarm calls facilitate some antipredatory benefits of group living but may endanger the caller by attracting the predator's attention. A number of hypotheses invoking kin selection and individual selection have been proposed to explain how such behaviour

Natural selection. III. Selection versus transmission and the levels of selection [PDF]

open access: yes, 2011
George Williams defined an evolutionary unit as hereditary information for which the selection bias between competing units dominates the informational decay caused by imperfect transmission.

Kin-Mediated Male Choice and Alternative Reproductive Tactics in Spider Mites

open access: yesBiology, 2020
Optimal outbreeding and kin selection theories state that the degree of kinship is a fundamental determinant in any mating system. However, the role of kinship in male choice and alternative reproductive tactics (ARTs) is poorly known.

Human kin detection [PDF]

open access: yes, 2015
Natural selection has favored the evolution of behaviors that benefit not only one's genes, but also their copies in genetically related individuals. These behaviors include optimal outbreeding (choosing a mate that is neither too closely related, nor ...

Influence of kinship and MHC class II genotype on visual traits in zebrafish larvae (Danio rerio). [PDF]

open access: yesPLoS ONE, 2012
Kin recognition can drive kin selection and the evolution of social behaviour. In zebrafish (Danio rerio, Hamilton 1822), kin recognition is based on olfactory and visual imprinting processes.
