For socialized animals,such as prinlates,emotions arc the expression of internal states,which may be recognized by others to adjust an in dividual's potential actions(Girard and Bellone 2020).Facial expressions are therefore important signals in communication(e.g.,happy or in pain)and can help individuals understand potential meanings between each other(Dolensek et al.2020).Facial expressions can be expressed and processed freely and are useful in social interactions and bonding(Waller et al.2016).

In social mammals, kinship is an important factor that often affects the interactions among individuals within groups. In primates that live in a multilevel society, kinship may affect affiliative patterns between individuals at different scales within the larger group. For this study, we use field observations and molecular methods to reveal the profiles of how kinship affects affiliative behaviors between individuals in a breeding band of wild golden snub-nosed monkeys (). We use a novel nonparametric test, the partition Mantel test, to measure independently the correlation between kinship and each of three affiliative behaviors. Our results show that more closely related females are more likely to groom each other. Average relatedness between adult females within the same one-male unit (OMU) is higher than that between adult females from different OMUs. We suggest that closely related females may reside in the same OMU in order to attain inclusive fitness benefits, and that kinship plays an important role in maintaining the social structure of this species.

Rank recognition allows social animals to adapt to complex and changeable environments and to cope with hierarchical relationships within their societies(Crone 2017).Rank recognition can improve the distribution of advantageous resources,individual adaptation,and social cohesion among group-living animals(Marmolejo-Ramos and Angiulli 2014).Empirical evidence suggests that rank recognition is a basic behavioral manifestation of social cognition adopted by a wide range of insects,birds,and mammals,including nonhuman primates(Schmitt and Fischer 2011;Smith et al.2017).Unlike most other vertebrates,primates have unusually large brains and form complex social groups.
