Coevolution of Facial Expression and Social Tolerance in Macaques

Abstract: The purpose of this study is to test the hypothesis that social tolerance drives the evolution of facial expression in macaques. Macaque species exhibit a range of social styles that reflect a continuum of social tolerance. Social interactions in more tolerant taxa tend to be less constrained by rank and kinship than in less-tolerant macaques. I predicted that macaques that are more tolerant would exhibit a wider range of facial displays than less-tolerant species because interactions that are open to negotiat… Show more

“…We already know that increased sociality and social tolerance correlates with increased complexity in vocal and visual signaling [Dobson, 2012;Maestripieri, 1999;McComb & Semple, 2005]. However, whether social tolerance and/or social complexity have any impact on the composition of multicomponent signals is unknown.…”

“…Social bonds usually have more weight than kinship or dominance status on their social behavior and communication . A growing body of evidence suggests that this increased social tolerance has an impact on the complexity of communication [Dobson, 2012;Maestripieri, 1999]. Crested macaques' behavioral repertoire has been described as especially rich and includes several signals uncommon or absent in other macaques [Thierry et al, 2000].…”

“…Duffy et al 2007; Gomes and Boesch 2009; Gilby et al 2013). Indeed, in other primate communication systems, it is the degree of social tolerance that increases signal complexity and flexibility (Maestripieri 1999; Dobson 2012), and in chimpanzee gestural communication an increased range of signals is employed for ‘social negotiation’ in the subtle regulation of complex social relationships (Hobaiter and Byrne 2014). …”

“…However, almost two‐thirds of the first post‐conflict signals exchanged between former opponents were an SBTF, and the CCT inflates to an astounding 52% if the SBTF is the only behavior included in the analysis. Higher CCT is one marker of egalitarian rather than despotic species (Dobson ). Mandrills exhibit mostly despotic features (e.g., high rates of unidirectional aggression, low tolerance for subordinates, and low levels of cooperation), and so we would not predict a high CCT for this species.…”
