“…strangers, which would probably be attacked (35). Yet, this prosociality is not merely kin favoritism because marmosets, just like other primates, recognize kin as shown by their ability to avoid inbreeding (36,37) and differentiate between related and nonrelated extragroup individuals (38). Nonetheless, kin selection may well have played a role in the origin of unsolicited prosociality (39), which subsequently was extended to actual and prospective social partners (40).…”

Human cooperation is unparalleled in the animal world and rests on an altruistic concern for the welfare of genetically unrelated strangers. The evolutionary roots of human altruism, however, remain poorly understood. Recent evidence suggests a discontinuity between humans and other primates because individual chimpanzees do not spontaneously provide food to other group members, indicating a lack of concern for their welfare. Here, we demonstrate that common marmoset monkeys (Callithrix jacchus) do spontaneously provide food to nonreciprocating and genetically unrelated individuals, indicating that other-regarding preferences are not unique to humans and that their evolution did not require advanced cognitive abilities such as theory of mind. Because humans and marmosets are cooperative breeders and the only two primate taxa in which such unsolicited prosociality has been found, we conclude that these prosocial predispositions may emanate from cooperative breeding.cooperative breeding ͉ non-human primates ͉ prosociality ͉ helping ͉ dictator game

“…In captivity, therefore, the presence of a breeding female may constrain other females' likelihood of ovulating and conceiving but, following conception, does not appear to further influence pregnancy, parturition or lactation. A similar pattern may occur in free-living marmosets: numerous subordinate females have been reported to give birth to live infants, and do not appear to be subjected to increased aggression or eviction (Digby 1995a;Lazaro-Perea et al 2000;Arruda et al 2005;Sousa et al 2005). …”

“…Typically, only a single dominant male and one or two dominant females breed; the remaining adults and immatures serve as non-reproductive alloparents. Microsatellite and mitochondrial DNA analyses of free-ranging groups indicate that mates are unrelated to one another, while in plurally breeding groups the two breeding females are often closely related to each other and to the remaining group members ( Nievergelt et al 2000;Faulkes et al 2003); however, population crashes and periods of instability can result in groups comprising unrelated individuals (Lazaro-Perea et al 2000;Faulkes et al 2003). Marmoset societies are therefore dynamic and unpredictable.…”

Reproductive skew in female common marmosets: what can proximate mechanisms tell us about ultimate causes?

2008

Common marmosets are cooperatively breeding monkeys that exhibit high reproductive skew: most subordinate females fail to reproduce, while others attempt to breed but produce very few surviving infants. An extensive dataset on the mechanisms limiting reproduction in laboratory-housed and freeliving subordinate females provides unique insights into the causes of reproductive skew. Non-breeding adult females undergo suppression of ovulation and inhibition of sexual behaviour; however, they receive little or no aggression or mating interference by dominants and do not exhibit behavioural or physiological signs of stress. Breeding subordinate females receive comparable amounts of aggression to non-breeding females but are able to conceive, gestate and lactate normally. In groups containing two breeding females, however, both dominant and subordinate breeders kill one another's infants. These findings suggest that preconception reproductive suppression is not imposed on subordinate females by dominants, at a proximate level, but is instead self-imposed by most subordinates, consistent with restraint models of reproductive skew. In contrast to restraint models, however, this self-suppression probably evolved not in response to the threat of eviction by dominant females but in response to the threat of infanticide. Thus, reproductive skew in this species appears to be generated predominantly by subordinate self-restraint, in a proximate sense, but ultimately by dominant control over subordinates' reproductive attempts.

“…In nearly every territorial encounter, a male from one group and a female from another group would cease behaving aggressively towards each other, move away from the rest of the group and copulate before returning to be aggressive to each other again. When a breeding animal disappeared from a group, the vacancy was filled rapidly, often by an animal previously seen engaged in territorial and assessment behaviour (Lazaro-Perea et al 2000). Scent marks produced by non-reproductive males and females at territory boundaries may provide information about quality (physical health, stamina, reproductive competence) and also individual identity, information that can influence mate choice decisions.…”

We describe the role of social odours in sexual arousal and maintaining pairbonds in biparental and cooperatively breeding primates. Social odours are complex chemical mixtures produced by an organism that can simultaneously provide information about species, kinship, sex, individuality and reproductive state. They are long lasting and have advantages over other modalities. Both sexes are sensitive to changes in odours over the reproductive cycle and experimental disruption of signals can lead to altered sexual behaviour within a pair. We demonstrate, using functional magnetic resonance imaging (fMRI), that social odours indicating reproductive state directly influence the brain areas responsible for sexual behaviour. Social odours also influence other brain areas typically involved in motivation, memory and decision making, suggesting that these signals have more complex functions in primates than mere sexual arousal. We demonstrate a rapid link between social odours and neuroendocrine responses that are modulated by a male's social status. Recent work on humans shows similar responses to social odours. We conclude with an integration of the importance of social odours on sexual arousal and maintaining pairbonds in socially biparental and cooperatively breeding species, suggesting new research directions to integrate social behaviour, neural activation and neuroendocrine responses.
