Variation in helper effort among cooperatively breeding bird species is consistent with Hamilton’s Rule by Green, J, Freckleton, R, Hatchwell, B

“…Our findings support the hypothesis that variation in helping behaviour among cooperatively breeding birds is consistent with Hamilton’s rule, indicating a key role for kin selection in the evolution of cooperative investment in social birds.…”

Evolution of helping and harming in heterogeneous populations by Rodrigues, A, Gardner, A

“…We highlight the prospect for using kin selection theory to explain within-population variation in social behavior, and point to the need for further theoretical and empirical investigation of this topic. © 2012 The Author(s). …”

Evolution of helping and harming in heterogeneous populations. by Rodrigues, A, Gardner, A

Cooperation and conflict in quorum-sensing bacterial populations. by Diggle, S, Griffin, A, Campbell, G, West, SA

“…We also show that a solution to the problem of exploitation is kin selection, if interacting bacterial cells tend to be close relatives. …”

The Human Family—Its Evolutionary Context and Diversity by Karen L. Kramer

“…To do so, first those traits that distinguish the human family are reviewed with an emphasis on the key contributions that behavioral ecology has made toward understanding dynamics within and between families, including life history, kin selection, reciprocity and conflict theoretical frameworks. …”

How Facial Expressions of Recipients Influence Online Prosocial Behaviors?—Evidence from Big Data Analysis on Tencent Gongyi Platform by Lihan He, Tianguang Meng

“…As a result, the conventional theories of kin selection and reciprocal altruism fall short in completely elucidating online prosocial behavior. …”

The origin of cooperation by Koduri, Nihal, Lo, Andrew W

“…This mechanism is distinct from standard biological explanations like kin selection, group selection, and reciprocity, and relies only on natural selection, and without recourse to notions of evolutionary stability.…”

The benefits of help in cooperative birds – non-existent or difficult to detect? by Downing, PA, Griffin, AS, Cornwallis, CK

“…In birds that breed cooperatively in family groups, adult offspring often delay dispersal to assist the breeding pair in raising their young. Kin selection is thought to play an important role in the evolution of this breeding system. …”

A general ploidy model for the evolution of helping in viscous populations. by Yeh, A, Gardner, A

“…There is growing interest in understanding how kin selection drives the evolution of social behaviours in viscous populations. …”

Assortment and the analysis of natural selection on social traits by McDonald, G, Farine, D, Foster, K, Biernaskie, J

“…We discuss links between social selection and kin selection theory, and we provide a practical guide for the social selection approach. …”

Pleiotropy, cooperation, and the social evolution of genetic architecture by dos Santos, M, Ghoul, M, West, S

“…The hypothesis is that linking cooperation with a trait that provides a personal (private) benefit can outweigh the cost of cooperation in situations when cooperation would not be favoured by mechanisms such as kin selection. We analysed the theoretical plausibility of this hypothesis, with analytical models and individual-based simulations. …”

Social semantics: altruism, cooperation, mutualism, strong reciprocity and group selection. by West, SA, Griffin, A, Gardner, A

“…In particular, we: (i) discuss confusion over the terms kin selection, mutualism, mutual benefit, cooperation, altruism, reciprocal altruism, weak altruism, altruistic punishment, strong reciprocity, group selection and direct fitness; (ii) emphasize the need to distinguish between proximate (mechanism) and ultimate (survival value) explanations of behaviours. …”

Inclusive fitness consequences of dispersal decisions in a cooperatively breeding bird, the long-tailed tit (Aegithalos caudatus) by Green, J, Hatchwell, B

“…This is especially true in social species, in which natal philopatry allows kin selection to operate, so direct and indirect components of inclusive fitness have to be considered when evaluating selection on dispersal. …”

Why die for my sibling? The positive association between identity fusion and imagined loss with endorsement of self-sacrifice by Vázquez, A, Ordoñana, JR, Whitehouse, H, Gómez, A

“…Overall, these results suggest that identity fusion might contribute towards explaining self-sacrifice among genetically related individuals as predicted by the theory of kin selection.…”

Social Support and Network Formation in a Small-Scale Horticulturalist Population by Cohen R. Simpson

“…Specifically, I test standard predictions of cooperation derived from the evolutionary theories of kin selection and reciprocal altruism alongside well-established sociological predictions around the self-organisation of asymmetric relationships. …”

Evolutionary theory of bacterial quorum sensing: when is a signal not a signal? by Diggle, S, Gardner, A, West, SA, Griffin, A

“…From an evolutionary perspective, intraspecies signalling can be explained using models such as kin selection, but when communication is described between species, it is more difficult to explain. …”

Is bacterial persistence a social trait? by Gardner, A, West, S, Griffin, A

“…This raises the possibility that persistence is a social trait, which can be influenced by kin selection. We develop a theoretical model to investigate the social consequences of persistence. …”

Cooperation and competition in pathogenic bacteria. by Griffin, A, West, SA, Buckling, A

“…One solution to this problem is if costly cooperative behaviours are directed towards relatives. This idea of kin selection has been hugely influential and applied widely from microorganisms to vertebrates. …”
