Genes for cooperation are not more likely to be carried by plasmids by Dewar, AE, Belcher, LJ, Scott, TW, West, SA

“…Overall, the vast majority of genes for cooperation are not located on plasmids, suggesting that the more general mechanism of kin selection is sufficient to explain the prevalence of cooperation across bacteria.…”

Cooperation peaks at intermediate disturbance. by Brockhurst, M, Buckling, A, Gardner, A

“…Higher rates of disturbance prevent this because the resulting bottlenecks increase genetic structuring (relatedness) promoting kin selection for cooperation. However, cooperation cannot be sustained under very frequent disturbance if population density remains below the level required for successful cooperation. …”

Coexistence of cooperation and defection in public goods games. by Archetti, M, Scheuring, I

“…Therefore it is generally believed that public goods can be produced only in the presence of repeated interactions (which allow reciprocation, reputation effects and punishment) or relatedness (kin selection). Cooperation, however, often occurs in the absence of iterations and relatedness. …”

Are greenbeards intragenomic outlaws? by Biernaskie, J, West, SA, Gardner, A

“…Hence, they can be favored by kin selection, irrespective of the degree of genealogical relationship between social partners. …”

Genomic imprinting and sex allocation. by Wild, G, West, SA

“…Genomic imprinting allows maternally and paternally derived alleles to have different patterns of expression (one allele is often silent). Kin selection provides an explanation of genomic imprinting because conflicts of interest can arise between paternally and maternally inherited alleles when they have different probabilities of being present in other individuals. …”

Grandparental Child Care in Europe: Evidence for Preferential Investment in More Certain Kin by Mirkka Danielsbacka, Antti O. Tanskanen, Markus Jokela, Anna Rotkirch

“…Theories of kin selection and parental investment predict stronger investment in children and grandchildren by women and maternal kin. …”

Sociogenetic Organization of the Red Honey Ant (<i>Melophorus bagoti</i>) by Nathan Lecocq de Pletincx, Serge Aron

“…Kin selection and inclusive fitness are thought to be key factors explaining the reproductive altruism displayed by workers in eusocial insect species. …”

“…Genomic imprinting allows maternally and paternally derived alleles to have different patterns of expression (one allele is often silent). Kin selection provides an explanation of genomic imprinting because conflicts of interest can arise between paternally and maternally inherited alleles when they have different probabilities of being present in other individuals. …”

Sexual conflict in viscous populations: the effect of the timing of dispersal. by Wild, G, Pizzari, T, West, SA

“…Our results support the suggestion that kin selection can influence the evolution of sexual conflict, but reveal that such a role might be more complex than previously appreciated when sex-specific life histories are taken into consideration. …”

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. …”

Phylogenetic relationships of Palaearctic Formica species (Hymenoptera, Formicidae) based on mitochondrial cytochrome B sequences. by Anna V Goropashnaya, Vadim B Fedorov, Bernhard Seifert, Pekka Pamilo

“…Ants of genus Formica demonstrate variation in social organization and represent model species for ecological, behavioral, evolutionary studies and testing theoretical implications of the kin selection theory. Subgeneric division of the Formica ants based on morphology has been questioned and remained unclear after an allozyme study on genetic differentiation between 13 species representing all subgenera was conducted. …”

Social navigation hypothesis of depressive disorder disproven by Marcin Piotr Nowak

“…Presented models, based on simplistic mathematical assumptions, don’t take into account kin selection and inclusive fitness. Conclusions SNH cannot explain the high prevalence of depressive symptoms and depressive disorder. …”

Ancestral social environments plus nonlinear benefits can explain cooperation in human societies by Nadiah P. Kristensen, Hisashi Ohtsuki, Ryan A. Chisholm

“…We use a mathematically tractable evolutionary model to formalise a chronological narrative that has previously only been investigated verbally: given that ancient humans interacted mostly with family members (genetic homophily), cooperation evolved first by kin selection, and then persisted in situations with nonlinear benefits as homophily declined or even if interactions with strangers became the norm. …”

THE PREREQUISITES OF PROSOCIAL BEHAVIOR IN HUMAN ONTOGENY by Irina M. Sozinova, Alexey A. Sozinov, Seppo J. Laukka, Yuri I. Alexandrov

“…These findings are discussed from the perspectives of kin selection theory, group selection theory and the system-evolutionary approach. …”

Understanding microbial divisions of labor by Zhang, Z, Claessen, D, Rozen, DE

“…We first discuss evolutionary arguments, derived from kin selection, that allow divisions of labor to be maintained in the face of non-cooperative cheater cells. …”

Ecological bases of philopatry and cooperation in Ethiopian wolves by Marino, J, Sillero-Zubiri, C, Johnson, P, Macdonald, D

“…Ecological reasons for philopatry and cooperation are frequently invoked when kin selection is an insufficient explanation. The Ethiopian wolf (Canis simensis) is a specialised rodent hunter that forms family groups with cooperative breeding but also lives as monogamous pairs in suboptimal areas. …”

Investigating the Impact of a Curse: Diseases, Population Isolation, Evolution and the Mother’s Curse by Maria-Anna Kyrgiafini, Themistoklis Giannoulis, Katerina A. Moutou, Zissis Mamuris

“…Finally, mito-nuclear co-adaptation, paternal leakage, and kin selection are some mechanisms that can mitigate the impact of the Mother’s Curse.…”

Insights from Melipona bicolor hybrid genome assembly: a stingless bee genome with chromosome-level scaffold by Natalia de Souza Araujo, Fernando Ogihara, Pedro Mariano Martins, Maria Cristina Arias

“…As the only known genuinely polygynous bee, M. bicolor’s genome provides a valuable resource for investigating sociality beyond kin selection. Results The genome was assembled employing a hybrid approach combining short and long reads, resulting in 241 contigs spanning 259 Mb (N50 of 6.2 Mb and 97.5% complete BUSCOs). …”

Diluted competition? Conflicts between full- and half-siblings in two adult generations by Tanskanen, A, Danielsbacka, M, Jokela, M, David-Barrett, T, Rotkirch, A

“…Respondents represent an older generation (born between 1945 and 1950, n = 2,015) and their adult children (born between 1962 and 1993, n = 1,565). Based on kin selection and parent–offspring conflict theory, we expect reports of any conflict to be more likely between full siblings than half-siblings, between maternal half-siblings than paternal half-siblings, and among the younger generation compared to the older generation. …”
