“…In the particular case where the individual learns its own cues to recognize its kin (without any prior encounter with kin individuals), the mechanism is called 'self-referent phenotype matching' (Hauber & Sherman 2001, Holmes 2004. Social learning and phenotype matching seems to have been adopted by the great majority of animals recognizing kin (Waldman 1981(Waldman , 1982Porter et al 1983;Gadagkar 1985;Getz & Smith 1986;Sun & Mü ller-Schwarze 1997;Mateo & Johnston 2000). Self-referent phenotype matching and recognition alleles concern a few examples of kin recognition, probably not due to their rarity but because they are so difficult to demonstrate (Mateo & Johnston 2000;Jansen & van Baalen 2006).…”

Kin discrimination and altruism in the larvae of a solitary insect

Kin selection theory predicts altruism between related individuals, which requires the ability to recognize kin from non-kin. In insects, kin discrimination associated with altruistic behaviour is well-known in clonal and social species but in very few solitary insects. Here, we report that the solitary larvae of a non-social insect Aleochara bilineata Gyll. (Coleoptera; Staphylinidae) show kin discrimination and sibling-directed altruistic behaviour. Larvae superparasitize more frequently the hosts parasitized by non-kin individuals than those hosts parasitized by siblings. Kin discrimination probably occurs by self-referent phenotype matching, where an individual compares its own phenotype with that of a non-familiar related individual, a mechanism rarely demonstrated in animals. The label used to recognize kin from non-kin corresponds to substances contained in the plug placed on the hosts by the resident larvae during the parasitization process. Kin competition induced by a limited larval dispersion may have favoured the evolution of kin recognition in this solitary species.

“…There is extensive evidence supporting both familiarity and phenotype matching among rodents [e.g. Belding’s ground squirrels (Holmes, 1986 b ); North American beaver, Castor canadensis (Sun & Müller‐Schwarze, 1997); golden hamsters (Heth, Todrank & Johnston, 1998; Mateo & Johnston, 2000); white‐footed deermice, Peromysus leucopus (Grau, 1982); spiny mouse, Acomys cahirinus (Porter, Matochik & Makin, 1983); reviewed for rodents by Mateo (2003)]. Recent primate studies have also suggested familiarity and/or phenotype matching as underlying mechanisms of paternal sibling discrimination, while fathers might use mating information as a proxy to recognize offspring (summarized in Table 3).…”

Paternal kin discrimination: the evidence and likely mechanisms

One of the most important assumptions of kin selection theory is that individuals behave differently towards kin than non-kin. In mammals, there is strong evidence that maternal kin are distinguished from non-kin via familiarity. However, little is known about whether or not mammals can also recognize paternal kin as many female mammals, including primates, mate with multiple males near the time of conception, potentially concealing paternal kinship. Genetic data in several mammalian species with a promiscuous mating system and male-biased dispersal reveal a high skew in male reproduction which leads to co-residing paternal half-siblings. In most primates, individuals also form stable bisexual groups creating opportunities for males to interact with their offspring. Here I consider close paternal kin co-resident in the same social group, such as father-offspring and paternal half-siblings (i.e. animals sharing the same father but who were born to different mothers) and review mammalian studies of paternal kin discrimination. Furthermore, I summarize the most likely mechanisms of paternal kin discrimination (familiarity and phenotype matching). When familiarity is the underlying mechanism, mothers and/or the sire could mediate familiarity among paternal half-siblings as well as between fathers and offspring assuming mothers and/or fathers can assess paternity. When animals use phenotype matching, they might use their fathers' template (when the father is present) or self (when the father is absent) to assess paternal kinship in others. Available evidence suggests that familiarity and phenotype matching might be used for paternal kin discrimination and that both mechanisms might apply to a wide range of social mammals characterized by a high skew in male reproduction and co-residence of paternal kin. Among primates, suggested evidence for phenotype matching can often have an alternative explanation, which emphasizes the crucial importance of controlling for familiarity as a potential confounding variable. However, the mechanism/s used to identify paternal kin might differ within a species (as a function of each individual's specific circumstances) as well as among species (depending upon the key sensory modalities of the species considered). Finally, I discuss the possible cues used in paternal kin discrimination and offer suggestions for future studies.

“…Phenotype matching involves the comparison of a conspecific's 'recognition cues' (i.e. phenotypic characteristics) to a learned or genetically dictated 'recognition template' (Porter et al, 1983;Hepper, 1986;Waldrnan, 1987;Wilson, 1987). Once the template is established, any conspecific can be compared and discrimination decisions can be based on the degree of match (i.e.…”
