A model of the biogeographical journey from Proto-pan to Pan paniscus
Primates, 2003Pan paniscus is unique in the group of African apes because of its range south of the Congo River. Examination of the bio-geographical journey of the genus Pan to the species P. paniscus is important when discussing the evolution of African apes.

Birth in bonobos (Pan paniscus): a case report
Atti della Società Toscana di Scienze Naturali Residente in Pisa Memorie serie B, 2011Birth in non-human primates has been described in several species but there is an almost total lack of data about the reactions of other group members towards the mother and the newborn. This report describes a delivery by a member (hereafter «the mother») of a captive group of bonobos (Pan paniscus) hosted at Apenheul Primate Park (The Netherlands ...

Periparturitional behavior of a bonobo (Pan paniscus)
American Journal of Primatology, 1989AbstractKnowledge of periparturitional behaviors in captive primates may contribute to infant survival and is particularly important for endangered species, such as the bonobo, or pygmy chimpanzee (Pan paniscus). Given that the bonobo is considered to be closely related to humans, such knowledge also may offer insights about the evolutionary ...

Pan paniscus and Pan troglodytes
1984Previous ape language studies have been undertaken with common chimpanzees (Pan troglodytes), orangutans (Pongo pygmaeus), and gorillas (Gorilla gorilla) (Gardner and Gardner, 1969; Rumbaugh, 1977, Savage-Rumbaugh, 1979; Miles, 1982; Patterson and Linden, 1981).

Abstract This chapter discusses how bonobos provide the great contrast to chimpanzee’s significance for assessing human nature. Bonobos exhibited broad behavioral contrasts to chimpanzees as they do not form aggressive male coalitions, patrol territorial boundaries, stealthily penetrate neighbors’ ranges, or kill outsiders.

Reconciliation and consolation in captive bonobos (Pan paniscus)
American Journal of Primatology, 2004AbstractAlthough reconciliation in bonobos (Pan paniscus) has previously been described, it has not been analyzed heretofore by the postconflict (PC) match‐control (MC) method. Furthermore, although reconciliation has been investigated before in this species, consolation has not.

Man and Pan paniscus: A karyologic comparison
Journal of Human Evolution, 1973Abstract The chromosome complement of Pan paniscus and man are compared by quinacrine fluorescence and G-banding. A hypothesis for the rearrangement and the reduction from 2n = 48 to 2n = 46 is presented.

Skeletal development inPan paniscuswith comparisons toPan troglodytes
American Journal of Physical Anthropology, 2012AbstractFusion of skeletal elements provides markers for timing of growth and is one component of a chimpanzee's physical development. Epiphyseal closure defines bone growth and signals a mature skeleton. Most of what we know about timing of development in chimpanzees derives from dental studies onPan troglodytes.

Hand Abnormalities in Pygmy Chimpanzees (Pan paniscus)
Folia Primatologica, 1987Hand deformities in 2 wild-born pygmy chimpanzees were investigated through dissection, linear measurements, bone mineral analysis and X-rays. Weight of tissue (skin, muscle, bone) was determined for each body segment (hand, forearm, upper arm), permitting comparison between the abnormal and normal upper limbs.

Case study: Scoliosis in a Bonobo (Pan paniscus)
Journal of Medical Primatology, 2017AbstractDifferential diagnosis of observed morphological features on an adult male bonobo skeleton was consistent with idiopathic scoliosis. Directional asymmetry was an order of magnitude higher compared with asymptomatic skeletons. This possible case of idiopathic scoliosis contributes to data that suggest a weaker tie between bipedalism and ...
