In primates, this transition is currently not well understood. Traditional verbal models appear insufficient to unravel the complex interplay of environmental and demographic factors involved in the evolution of primate sociality, and recent phylogenetic reconstructions have produced conflicting results. We therefore analyze a theoretical model for the evolution of female social philopatry that sheds new light on the question why most primates live in groups. In individual‐based simulations, we study the evolution of dispersal strategies of both resident females and their offspring. The model reveals that social philopatry can evolve through kin selection, even if retention of offspring is costly in terms of within‐group resource competition and provides no direct benefits. Our model supports the role of predator avoidance as a selective pressure for group‐living in primates, but it also suggests that a second benefit of group‐living, communal resource defense, might be required to trigger the evolution of sizable groups. Lastly, our model reveals that seemingly small differences in demographic parameters can have profound effects on primate social evolution."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659"],["dc.description.sponsorship","Deutscher Akademischer Austauschdienst http://dx.doi.org/10.13039/501100001655"],["dc.description.sponsorship","H2020 European Research Council http://dx.doi.org/10.13039/100010663"],["dc.identifier.doi","10.1002/ajpa.24123"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/81480"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.publisher","John Wiley \\u0026 Sons, Inc."],["dc.relation.eissn","1096-8644"],["dc.relation.issn","0002-9483"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited."],["dc.title","The evolution of social philopatry in female primates"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

This study uses models of reproductive skew theory as a new approach to explain this unusual group composition, in particular the high number of males, in a representative of these lemurs, the redfronted lemur (Eulemur fulvus rufus). We tested two central predictions of “concession” models of reproductive skew theory, which assume that subordinates may be allowed limited reproduction by dominant group members as an incentive to remain in the group, thereby increasing the group’s overall productivity. Accordingly, relatives are predicted to receive less reproduction than non-relatives, and the overall amount of reproductive concessions given to subordinates is predicted to increase as the number of subordinates increases. In addition, we tested whether the number of females in a group, a variable not previously incorporated in reproductive skew theory, affected reproductive skew among males. Using microsatellite analyses of tissue DNA, we determined paternities of 49 offspring born into our study population in Kirindy forest (western Madagascar) since 1996 to determine patterns of male reproductive skew to test these predictions. Our analyses revealed remarkable reproductive skew, with 71% of all infants being sired by dominant males, but both predictions of reproductive skew models could not be supported. Instead, the number of females best predicted the apportionment of reproduction among the males in this species, suggesting that current reproductive skew models need to incorporate this factor to predict reproductive partitioning among male primates and perhaps other group-living mammals."],["dc.identifier.doi","10.1007/s00265-008-0577-5"],["dc.identifier.gro","3150782"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/3493"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7572"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","0340-5443"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Mutual tolerance or reproductive competition?
