Kin recognition: an overview of conceptual issues, mechanisms and evolutionary theory

An introduction to KR is provided, including an overview of the main debates, the underlying mechanisms and evolutionary analyses, and a classification scheme of the different mechanisms based on whether they are considered to be KR in the broad or in the narrow sense.

Identity Signaling and Patterns of Cooperative Behavior.

A simple model is developed showing that learning a kin recognition template is sufficient to increase and maintain diversity in genetic traits used for kin recognition, and suggests that phenotypes used for recognition may be true signals of genetic identity.

Kith or Kin? Familiarity as a Cue to Kinship in Social Birds

It is concluded that while familiarity as a mechanism for kin recognition may be more parsimonious and widespread than genetic mechanisms, its apparent simplicity as a decision rule governing social interactions may be deceptive.

Perspectives: Hamilton's Legacy: Mechanisms of Kin Recognition in Humans

The behavior literature is replete with examples of individuals exhibiting costly acts that benefit someone else. These examples troubled Darwin so much so that he thought they would be fatal to his

Kin recognition in guppies uses self-referencing on olfactory cues

It is shown that guppies discriminate among their full- and maternal half-siblings, which can only be explained by self-referencing, and that olfactory communication is both necessary and sufficient for kin discrimination.

Olfactory Signals Involved in Kin Recognition in Zebrafish

Kin recognition requires more stringent criteria when proximity and familiarity with conspeciÞcs are not sufÞciently reliable to detect true genetic relatedness.

Kin discrimination in sticklebacks is mediated by social learning rather than innate recognition

Adult, non-reproductive three-spined sticklebacks, Gasterosteus aculeatus, prefer to shoal with kin and this preference was shown for familiar as well as for unfamiliar individuals, suggestingKin recognition in stickleback is most likely mediated by social learning.

Kin Discrimination in Protists: From Many Cells to Single Cells and Backwards

It is emphasized that because protists are among the most ancient organisms on Earth, belong to multiple taxonomic groups and occupy all environments, they can be central to reexamining traditional hypotheses in the field of kin recognition, reforming concepts, and generating new knowledge.



Kin recognition: function and mechanism in avian societies.

Do animals really recognize kin?

Kin Recognition Mechanisms: Phenotypic Matching or Recognition Alleles?

Kin recognition in the absence of obvious opportunities to learn one's kin is an important biological phenomenon and elucidating the mechanism by which the recognition is achieved is a major

A test of alternative hypotheses for kin recognition in cannibalistic tiger salamanders

The necessary condition for kin selection, Hamilton’s rule, was met and the results implicate kin selection as the overriding reason that cannibalistic tiger salamanders discriminate kin.

Problems of kin recognition.

Genetic control for sibling recognition?

Tadpoles were separated before hatching and reared apart from other individuals, results suggest that the ability of these tadpoles to discriminate between siblings and non-siblings has some innate component.

Kin preference in infant Macaca nemestrina

It is shown that young pigtail macaques prefer to interact with a related over an unrelated monkey in a laboratory test, suggesting that kin recognition can occur in the absence of prior association with relatives.

The Ontogeny of Kin Recognition in Two Species of Ground Squirrels1

The laboratory work shows that in both species, preweaned pups reared together, whether they are biological siblings or cross-fostered (unrelated) nestmates, are equally aggressive in subsequent paired arena tests, so pups that share a natal nest are treated like siblings.

The function of kin discrimination

Two postulates derived from inclusive fitness theory that fitness benefits toward kin are correlated with degree of relatedness and that social behavior of members of a kin group is always cooperative are refuted by analyses of the social dynamics of yellowbellied marmots.
