New records and confirmation of the presence of three species of primates (Mammalia, Primates) in southwestern Colombia [PDF]
Check List, 2020 Cebus albifrons (Humboldt, 1812); Sapajus apella (Linnaeus, 1758) and Aotus lemurinus I. Geoffroy, 1843 are widely distributed primates in Colombia. Despite this, there are gaps in the occurrence of these species in the southwestern part of the country ...

Are capuchin monkeys (Cebus apella) inequity averse? [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 It has been reported that capuchin monkeys reject a less preferred food (LPF) when they see a partner capuchin receive a more preferred food (PF) for performing the same task. This behaviour was taken as evidence of ‘inequity aversion’, but an alternative hypothesis is that capuchins reject the LPF because of the mere presence of the PF. We tested this

Postconflict Behaviour in Brown Capuchin Monkeys (Cebus apella) [PDF]
Folia Primatologica, 2009 Postconflict affiliation has been mostly studied in Old World primates, and we still lack comparative research to understand completely the functional value of reconciliation. Cebus species display great variability in social characteristics, thereby providing a great opportunity for comparative studies.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?
Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by
