“…Because animals pulled more frequently in these two conditions compared with the experimental control condition, they understood the apparatus. 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).…”

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

“…Subsequent research on the details of territorial interactions (Lazaro-Perea 2001) suggested that these interactions did not function solely to display aggression towards others, but also allowed marmosets to assess potential mates in other groups. 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.…”

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.

“…sub-dominant males help by increasing pups survival during winter; Allainé & Thureau 2004), they actively defend their territories overlapping part of them with neighbours (Perrin 1993b) and they use scent-marking behaviours for territory defence (Lenti Boero 1995). Interestingly, whereas the role of helpers in territorial defence has been shown in many species (Lazaro-Perea 2001;Bruintjes & Taborsky 2008;Le Vin et al 2011), direct evidences of their involvement in supporting the rRHP or the GA hypothesis are missing. 4 In particular we evaluated the role of scent marking in territorial defence in Alpine marmots by looking at where the behaviour was primarily performed (i.e.…”

In social mammals, territory size and shape vary according to the number and strength of neighbour individuals competing for resources. Two main theories have been proposed to explain this variability: the Group Augmentation (GA) and the realized Resource Holding Potential (rRHP) hypotheses. The first states that the outcome of the interactions among groups depends on the total number of individuals in the group while the second states that only the number of animals directly involved in intergroup competition determines this outcome. We collected data on space use of individually tagged Alpine marmots ( Marmota marmota), a cooperative breeding species that overlaps part of its territory with neighbouring groups. In accordance with the rRHP hypothesis, we found that groups having higher proportion of helpers, rather than higher total number of individuals, had lower percentage of the territory overlapping with neighbouring groups and a larger area available for individual exclusive use.
