Problem solving in European bison (
Royal Society Open Science, 2021 The ability to solve novel problems is crucial for individual fitness. However, studies on problem solving are usually done on few taxa, with species with low encephalization quotient being rarely tested.

Ecological Drivers of Non-kin Cooperation in the Hymenoptera
Frontiers 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.

Kin selection and altruism [PDF]
Current Biology, 2019 Natural selection is predicated on the 'struggle for existence': life is short, cruel and, whether through predation, disease or starvation, often ends traumatically. It would seem that in such a dog-eat-dog world, organisms ought to act selfishly, and avoid reducing their fitness (expected survival and reproductive success) by expending time and ...

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

Frontiers 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.

Kinship underlies costly cooperation in Mosuo villages [PDF]
Royal Society Open Science, 2018 The relative importance of social evolution theories such as kin selection, direct reciprocity and need-based transfers in explaining real-world cooperation is the source of much debate.

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

Hamilton's rule and its discontents [PDF]
, 2013 In an incendiary 2010 Nature article, M. A. Nowak, C. E. Tarnita and E. O. Wilson present a savage critique of the best known and most widely used framework for the study of social evolution, W. D. Hamilton’s theory of kin selection.

Does the kin orientation of a British woman’s social network influence her entry into motherhood? [PDF]
, 2013 BACKGROUND The influence of family and friends on an individual's fertility has long been an important topic within demography. Researchers who focus on social network effects and evolutionary demography have shown a renewed interest in this issue in ...

Integrating the theories of kin selection and sexual selection [PDF]
, 2019 Sexual selection and kin selection are both considered special cases of natural selection. However, both topics have developed almost entirely independently, with a prominent review even suggesting that there is no overlap between the two theories.
