Chimpanzees, Pan troglodytes, follow gaze direction geometrically

Animal Behaviour, 1999
Two experiments on chimpanzee gaze following are reported. In the first, chimpanzee subjects watched as a human experimenter looked around various types of barriers. The subjects looked around each of the barriers more when the human had done so than in a control condition (in which the human looked in another direction).

Imitation in neonatal chimpanzees (Pan troglodytes)

Developmental Science, 2004
AbstractThis paper provides evidence for imitative abilities in neonatal chimpanzees (Pan troglodytes), our closest relatives. Two chimpanzees were reared from birth by their biological mothers. At less than 7 days of age the chimpanzees could discriminate between, and imitate, human facial gestures (tongue protrusion and mouth opening).

Molar development in common chimpanzees (Pan troglodytes)

Journal of Human Evolution, 2007
Numerous studies have reported on enamel and dentine development in hominoid molars, although little is known about intraspecific incremental feature variation. Furthermore, a recent histological study suggested that there is little or no time between age at chimpanzee crown completion and age at molar eruption, which is unlikely given that root growth

Diabetes mellitus in the Chimpanzee (Pan troglodytes)

Journal of Medical Primatology, 1981
Glucose intolerance was found in four adult chimpanzees. The response of glucose, insulin, C-peptide, and glucagon to intravenous glucose and tolbutamide stimulations revealed impaired glucose clearance, deficient pancreatic secretion of insulin and C-peptide, and elevated glucagon levels.

Etiology of reactive arthritis in Pan paniscus, P. troglodytes troglodytes, and P. troglodytes schweinfurthii

American Journal of Primatology, 2005
AbstractThe character of arthritis has not received the same attention in Pan paniscus as it has in P. troglodytes. Reactive arthritis (a form of spondyloarthropathy) in the latter has been considered to be either a sexually transmitted or an infectious‐agent diarrhea‐related disorder. The unique sexual promiscuity of P.

Pan paniscus and Pan troglodytes

1984
Previous 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).

Finger drawing by infant chimpanzees ( Pan troglodytes )

Animal Cognition, 2003
We introduced a new technique to investigate the development of scribbling in very young infants. We tested three infant chimpanzees to compare the developmental processes of scribbling between humans and chimpanzees. While human infants start to scribble on paper at around the age of 18 months, our 13- to 23-month-old infant chimpanzees had never been

Causal capture effects in chimpanzees (Pan troglodytes)

Cognition, 2017
Extracting a cause-and-effect structure from the physical world is an important demand for animals living in dynamically changing environments. Human perceptual and cognitive mechanisms are known to be sensitive and tuned to detect and interpret such causal structures.
