“…More recent empirical work, however, has revealed that a wide range of mammalian species and some birds engage in coalitionary behaviour (reviewed by Smith et al, 2010), including several social carnivores (e.g., hyenas, Crocuta crocuta: Zabel et al, 1992;Engh et al, 2002;Wahaj et al, 2004;ring- Rowell & Rowell, 1993), some perissodactyls (e.g., plain zebra, Equus quagga: Schilder, 1990), one proboscid (African elephant, Loxondonta africana: Lee, 1987), and some birds (e.g., rooks, Corvus frugilegus: Seed et al, 2007;ravens, Corvus corax: Fraser & Bugnyar, 2012).…”

“…As we will see below, coalitions can serve different functions (van Schaik et al, 2006); they can be observed among different sex and age classes (reviewed in Chapais, 1995); they can involve kin (e.g., Riss & Goodall, 1977;Chagnon & Bugos, 1979;Wahaj et al, 2004), non-kin (e.g., Vigilant et al, 2001;Langergraber et al, 2007;Schülke et al, 2010), and friends or acquaintances (Hruschka & Henrich, 2006;Hruschka, 2010). As this brief review makes clear, coalitionary patterns are varied, and understanding this diversity would be greatly enhanced by formal modelling that would allow us to identify the general conditions under which coalition formation is expected to evolve, characterize the degree of variability expected, and predict when coalitions should, and should not, occur.…”

“…There is considerable evidence of so-called nepotism in coalition formation among primates and other animals (Silk, 2002;Wahaj et al, 2004;Chapais, 2006;Smith et al, 2010;see below). One prominent example involves female Old World monkeys, such as baboons, vervets and macaques, where females intervene in disputes between their relatives and unrelated individuals, typically supporting the former against the latter (Silk et al, 2004).…”

“…In some species mothers are known to provide aid to sons in conflicts with other males (Surbeck et al, 2011; see also Chapais, 1983;Kutsukake & Hasegawa, 2005). Although the role of paternal kinship has rarely been considered in studies of coalition formation, its influence is strongly suggested in adult female mountain gorillas (Watts, 1997), adult female rhesus macaques (Widdig et al, 2006), and spotted hyenas (Wahaj et al, 2004).…”

Coalitions and alliances are ubiquitous in humans and many other mammals, being part of the fabric of complex social systems. Field biologists and ethologists have accumulated a vast amount of data on coalition and alliance formation, while theoretical biologists have developed modelling approaches. With the accumulation of empirical data and sophisticated theory, we are now potentially able to answer a host of questions about how coalitions emerge and are maintained in a population over time, and how the psychology of this type of cooperation evolved. Progress can only be achieved, however, by effectively bridging the communication gap that currently exists between Coalitions in theory and reality empiricists and theoreticians. In this paper, we aim to do so by asking three questions: (1) What are the primary questions addressed by theoreticians interested in coalition formation, and what are the main building blocks of their models? (2) Do empirical observations support the assumptions of current models, and if not, how can we improve this situation? (3) Has theoretical work led to a better understanding of coalition formation, and what are the most profitable lines of inquiry for the future? Our overarching goal is to promote the integration of theoretical and field biology by motivating empirical scientists to collect data on aspects of coalition formation that are currently poorly quantified and to encourage theoreticians to develop a comprehensive theory of coalition formation that is testable under real-world conditions.

“…There is evidence from a number of social animals that individuals can recognize paternal sibs (Holmes 1986;Alberts 1999;Wahaj et al 2004), suggesting that the mechanisms are in place for specific discrimination between maternal and paternal relatives. Furthermore, two separate primate studies have shown that this kin recognition can lead to altered behaviour, in that within groups females do bias their social behaviour towards their female paternal sisters (Widdig et al 2001;Smith et al 2003).…”

Genomic imprinting refers to the parent-of-origin-specific epigenetic marking of a number of genes. This epigenetic mark leads to a bias in expression between maternally and paternally inherited imprinted genes, that in some cases results in monoallelic expression from one parental allele. Genomic imprinting is often thought to have evolved as a consequence of the intragenomic conflict between the parental alleles that occurs whenever there is an asymmetry of relatedness. The two main examples of asymmetry of relatedness are when there is partiality of parental investment in offspring (as is the case for placental mammals, where there is also the possibility of extended postnatal care by one parent), and in social groups where there is a sex-biased dispersal. From this evolutionary starting point, it is predicted that, at the behavioural level, imprinted genes will influence what can broadly be termed bonding and social behaviour. We examine the animal and human literature for examples of imprinted genes mediating these behaviours, and divide them into two general classes. Firstly, mother-offspring interactions (suckling, attachment and maternal behaviours) that are predicted to occur when partiality in parental investment in early postnatal offspring occurs; and secondly, adult social interactions, when there is an asymmetry of relatedness in social groups. Finally, we return to the evolutionary theory and examine whether there is a pattern of behavioural functions mediated by imprinted genes emerging from the limited data, and also whether any tangible predictions can be made with regards to the direction of action of genes of maternal or paternal origin.

Female social relationships among primates are thought to be shaped by socio-ecological factors and phylogenetic constraints. We suggest that patterns of paternal relatedness among females influence measures of social tolerance that have been used to classify species into different social relationship categories. As kin support and kin preference have only been measured for matrilineal kin and related individuals exchange less aggression and have a higher conciliatory tendency, the observed low nepotism levels and high tolerance levels may be an artifact of hidden paternal relatedness among the nonkin category. Using comparative data on macaques, we investigate this hypothesis using male reproductive skew as a proxy for paternal relatedness. Within the limitations of the study we show that populations classified as being less nepotistic, and more tolerant exhibit higher levels of reproductive skew. This first result and the reasoning behind may motivate future students of social relationships to take paternal relatedness into consideration. Potential implications of this finding if repeated with larger samples include that variation in aspects of macaque social relationships may be explained without considering phylogeny or the strength of between-group contest competition for food.
