An Experimental Study of Kin Selection [PDF]

open access: bronzeEvolution, 1980
In this paper, I report the results of an experimental study of kin selection and its influence on the tendency of larvae to cannibalize eggs in the flour beetle, Tribolium confusum. Kin selection has been defined by Maynard Smith (1964, 1976) as that evolutionary process which occurs when individuals within a randomly mating population interact with ...

Monogamy and high relatedness do not preferentially favor the evolution of cooperation [PDF]

open access: yesBMC Evolutionary Biology, 2011
Background Phylogenetic analyses strongly associate nonsocial ancestors of cooperatively-breeding or eusocial species with monogamy. Because monogamy creates high-relatedness family groups, kin selection has been concluded to drive the evolution of ...

Genes, individuals, and kin selection [PDF]

open access: greenProceedings of the National Academy of Sciences, 1981
The altruistic-gene theory of kin selection requires conditions so improbable that its reality is doubtful. The gene-quantity theory, including the theory of inclusive fitness, assumes that selection acts on sums of kins' genes, but no effective mechanism is apparent.

Blood is not always thicker than water: The limited effect of kin selection on human kinship in the traditional Chinese family [PDF]

open access: yesCurrent 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

Effects of soil fertility and toxicity on the performance of Chenopodium quinoa (Willd) plants in kin and non-kin interactions [PDF]

open access: yesPlant Signaling & Behavior
Kin 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

Genetic Relatedness Promotes Equal Contributions of Males and Females to Brood Care in a Biparental Cichlid Fish [PDF]

open access: yesEcology and Evolution
Kin 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 ...
