A comparison of bonobo and chimpanzee tool use: evidence for a female bias in the Pan lineage
Please cite this article in press as: Gruber, T., Behaviour (2010), doi:10.1016/j.anbehav.201 Chimpanzees, Pan troglodytes, are themost sophisticated tool-users among all nonhumanprimates. From an evolutionary perspective, it is therefore puzzling that the tool use behaviour of their closest living primate relative, the bonobo, Pan paniscus, has been described as particularly poor. However, onl...

meaning that human observers were also there on a regular basis. Second, because Psydrax trees are relatively short with sparse canopies, it was easy for the observer to notice the dead body. We may not have been able to notice the remains if a higher and denser-canopied tree were involved or in a place less frequented by the chimpanzees. In such cases, we cannot solve the disappearances of inf...
متن کاملFoundations of cumulative culture in apes: improved foraging efficiency through relinquishing and combining witnessed behaviours in chimpanzees (Pan troglodytes)
A vital prerequisite for cumulative culture, a phenomenon often asserted to be unique to humans, is the ability to modify behaviour and flexibly switch to more productive or efficient alternatives. Here, we first established an inefficient solution to a foraging task in five captive chimpanzee groups (N = 19). Three groups subsequently witnessed a conspecific using an alternative, more efficien...
متن کاملTerrestrial nest-building by wild chimpanzees (Pan troglodytes): implications for the tree-to-ground sleep transition in early hominins.
Nest-building is a great ape universal and arboreal nesting in chimpanzees and bonobos suggests that the common ancestor of Pan and Homo also nested in trees. It has been proposed that arboreal nest-building remained the prevailing pattern until Homo erectus, a fully terrestrial biped, emerged. We investigated the unusual occurrence of ground-nesting in chimpanzees (Pan troglodytes), which may ...
متن کاملHow Abnormal Is the Behaviour of Captive, Zoo-Living Chimpanzees?
BACKGROUND Many captive chimpanzees (Pan troglodytes) show a variety of serious behavioural abnormalities, some of which have been considered as possible signs of compromised mental health. The provision of environmental enrichments aimed at reducing the performance of abnormal behaviours is increasing the norm, with the housing of individuals in (semi-)natural social groups thought to be the m...
