Previous research reported that the responses were unrelated to sex, but immatures showed more object exploration than adults in wild chacma baboons (Papio ursinus) and geladas (Theropithecus

It is also noteworthy the presence at Cueva Victoria of the large cercopithecid Theropithecus
(Gibert et al., 1995).
For the study, Thore Bergman, an assistant professor of psychology and ecology and evolutionary biology at the University of Michigan, looked at individual recognition in male geladas (Theropithecus
gelada, close relatives of baboons) that live in fluid, multilevel groups that can number more than 1,200 individuals - 10 times larger than baboon groups.
To test this hypothesis, dental microwear was observed in 15 individuals from Gorilla gorilla (n = 3), Pan troglodytes (n = 2), Theropithecus
gelada (n = 1), Papio cynocephalus (n= 2), Papio anubis (n = 2), Papio ursinus (n = 2), Cebus apella (n =2) and Pongo pygmaeus (n = 1) using low-magnification stereomicroscopy with an external and moveable light source.
Similarly, PTLV-3s exhibit broad diversity among NHPs in the wild; currently, 3 subtypes have been suggested according to the geographic origin of the strains (17): East African STLV-3 subtype A includes STLV-3 (PH969) found in a baboon (Papio hamadryas) from Eritrea (18) and from captive gelada baboons (Theropithecus
gelada) (19); West and Central African STLV-3 subtype B includes STLV-3 (CTO-604) and STLV-3 (CTO-602) found among mangabeys (Cercocebus torquatus) from Cameroon (20) and STLV-3 (PPAF3) from baboons (P.

No entanto, este comportamento foi observado em esquilos (Owings & Coss, 1977) e em algumas especies de primatas, como: babuinos gelada (Theropithecus
gelada; Iwamoto, Mori, Kawai & Bekele, 1996), sagui-geoffroy (Callithrix geoffroyi; Passamani, 1995), Hanuman langur (Semnopithecus entellus; Srivastava, 1991) e sagui-de-cara-suja (Saguinus fuscicollis nigrifons; Bartecki & Heymann, 1987).
