This structure arises from the limits of our cognitive capacity and the different amounts of resources required by different relationships. However, it is unknown whether nonhuman primate species organize their affiliative relationships following the same pattern. We here show that the time chimpanzees devote to grooming other individuals is well described by the same model used for human relationships, supporting the existence of similar social signatures for both humans and chimpanzees. Furthermore, the relationship structure depends on group size as predicted by the model, the proportion of high-intensity connections being larger for smaller groups. 000121147 536__ $$9info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/PGC2018-098186-B-I00 000121147 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000121147 590__ $$a4.6$$b2022 000121147 592__ $$a0.973$$b2022 000121147 591__ $$aMULTIDISCIPLINARY SCIENCES$$b22 / 73 = 0.301$$c2022$$dQ2$$eT1 000121147 593__ $$aMultidisciplinary$$c2022$$dQ1 000121147 594__ $$a7.5$$b2022 000121147 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000121147 700__ $$aDoldán-Martelli, Victoria 000121147 700__ $$aCronin, Katherine A. 000121147 700__ $$aHaun, Daniel B.
