INTRODUCTIONThe term “social monogamy” has been used to describe social groups comprising one adult female, one adult male, and their nonbreeding offspring (Lukas & Clutton‐Brock, ). It occurs rarely among mammals (9% of species), but is relatively common among primates (29% of species) (Lukas & Clutton‐Brock, ). Given its prevalence in the latter group, including some human populations (Low, ; Scelza, ), there has been a large amount of research aimed at understanding the evolution of this social organization (e.g., Fernandez‐Duque, ; Fuentes, ; Opie, Atkinson, Dunbar, & Shultz, ; Tecot, Singletary, & Eadie, ). Importantly, however, socially monogamous groups may or may not represent strict nuclear families (single pair parents and their offspring), and this has implications for evolutionary and behavioral studies (Palombit, ; Tecot et al., ).Differences between inferred nuclear family relationships and actual relatedness of group members is often described as a distinction between social monogamy and “genetic monogamy” (Huck, Fernandez‐Duque, Babb, & Schurr, ; Lukas & Clutton‐Brock, ; Ophir, Phelps, Sorin, & Wolff, ). The latter refers to adult pairs that exhibit exclusive parentage of the offspring (Goossens et al., ; Ophir et al., ). Lack of concordance between these two aspects of sociality is
