Social bonds and genetic ties: Kinship association and affiliation in a community of bonobos (Pan paniscus) [PDF]
, 1999 Studies of captive populations of bonobos suggest that females are more gregarious than males. This seems to contradict assumed sex-differences in kinship deriving from a speciestypical dispersal pattern of female exogamy and male philopatry.

The direct perception hypothesis: perceiving the intention of another’s action hinders its precise imitation [PDF]
, 2014 We argue that imitation is a learning response to unintelligible actions, especially to social conventions. Various strands of evidence are converging on this conclusion, but further progress has been hampered by an outdated theory of perceptual ...

Biological Reviews, EarlyView.ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Aging and sex affect soluble alpha klotho levels in bonobos and chimpanzees
Frontiers in Zoology, 2018 Background Throughout life, physiological homeostasis is challenged and the capacity to cope with such challenges declines with increasing age. In many species, sex differences exist in life expectancy.

Asymmetries in the Hippocampus and Amygdala of Chimpanzees (Pan troglodytes). [PDF]
Behavioral Neuroscience, 2004 Magnetic resonance imaging was used to measure the hippocampal and amygdalar volumes of 60 chimpanzees (Pan troglodytes). An asymmetry quotient (AQ) was then used to calculate the asymmetry for each of the structures. A one-sample t test indicated that there was a population-level right hemisphere asymmetry for the hippocampus. There was no significant

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution
Biological Reviews, EarlyView.ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Utterance evolution: the road to generative, combinatorial communicators
Biological Reviews, EarlyView.ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Intracranial arachnoid cysts in a chimpanzee (Pan troglodytes) [PDF]
Primates, 2013 An intracranial arachnoid cyst was detected in a 32-year-old, 44.6-kg, female chimpanzee at the Primate Research Institute, Kyoto University. Magnetic resonance imaging (MRI) and computed tomography (CT) were performed and the cognitive studies in which she participated were reviewed.
