A Comparison Between Bonobos and Chimpanzees: A Review and Update (2016)
Journal Article
Gruber, T., & Clay, Z. (2016). A Comparison Between Bonobos and Chimpanzees: A Review and Update. Evolutionary Anthropology, 25(5), 239-252. https://doi.org/10.1002/evan.21501

Chimpanzees (Pan troglodytes) and bonobos (P. paniscus) are our closest living relatives, with the human lineage diverging from the Pan lineage only around five to seven Mya, but possibly as early as eight Mya.1–2 Chimpanzees and bonobos even share g...

Bonobos (Pan paniscus) vocally protest against violations of social expectations (2016)
Journal Article
Clay, Z., Ravaux, L., de Waal, F. B., & Zuberbühler, K. (2016). Bonobos (Pan paniscus) vocally protest against violations of social expectations. Journal of Comparative Psychology, 130(1), 44-54. https://doi.org/10.1037/a0040088

Research has shown that great apes possess certain expectations about social regularities and both perceive and act according to social rules within their group. During natural and experimentally induced contexts, such as the inequitable distribution... Read More about Bonobos (Pan paniscus) vocally protest against violations of social expectations.

Obstacles and catalysts to peaceful coexistence in chimpanzees and bonobos. (2016)
Journal Article
Clay, Z., de Waal, F. B., & Furuichi, T. (2016). Obstacles and catalysts to peaceful coexistence in chimpanzees and bonobos. Behaviour, 153(9-11), 1293-1330. https://doi.org/10.1163/1568539x-00003335

As our closest living relatives, comparisons of the social lives and behavioural ecologies of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) provide relevant insights into the evolutionary constraints of peaceful coexistence in Hominid soci...

Functional flexibility in wild bonobo vocal behaviour (2015)
Journal Article
Clay, Z., Archbold, J., & Zuberbühler, K. (2015). Functional flexibility in wild bonobo vocal behaviour. PeerJ – the Journal of Life & Environmental Sciences, 3, Article e1124. https://doi.org/10.7717/peerj.1124

A shared principle in the evolution of language and the development of speech is the emergence of functional flexibility, the capacity of vocal signals to express a range of emotional states independently of context and biological function. Functiona... Read More about Functional flexibility in wild bonobo vocal behaviour.

Young Children Make Their Gestural Communication Systems More Language-Like: Segmentation and Linearization of Semantic Elements in Motion Events (2014)
Journal Article
Clay, Z., Pople, S., Hood, B., & Kita, S. (2014). Young Children Make Their Gestural Communication Systems More Language-Like: Segmentation and Linearization of Semantic Elements in Motion Events. Psychological Science, 25(8), 1518-1525. https://doi.org/10.1177/0956797614533967

Research on Nicaraguan Sign Language, created by deaf children, has suggested that young children use gestures to segment the semantic elements of events and linearize them in ways similar to those used in signed and spoken languages. However, it is... Read More about Young Children Make Their Gestural Communication Systems More Language-Like: Segmentation and Linearization of Semantic Elements in Motion Events.

Sex and strife: post-conflict sexual contacts in bonobos. (2014)
Journal Article
Clay, Z., & de Waal, F. B. (2015). Sex and strife: post-conflict sexual contacts in bonobos. Behaviour, 152(3-4), 313-334. https://doi.org/10.1163/1568539x-00003155

Sexual contacts are thought to play an important role in regulating social tension in bonobos (Pan paniscus), and are especially common following aggressive conflicts, either between former opponents or involving bystanders. Nevertheless, research on... Read More about Sex and strife: post-conflict sexual contacts in bonobos..

Multi-Modal Use of a Socially Directed Call in Bonobos (2014)
Journal Article
Genty, E., Clay, Z., Hobaiter, C., & Zuberbühler, K. (2014). Multi-Modal Use of a Socially Directed Call in Bonobos. PLoS ONE, 9(1), Article e84738. https://doi.org/10.1371/journal.pone.0084738

‘Contest hoots’ are acoustically complex vocalisations produced by adult and subadult male bonobos (Pan paniscus). These calls are often directed at specific individuals and regularly combined with gestures and other body signals. The aim of our stud...

Development of socio-emotional competence in bonobos (2013)
Journal Article
Clay, Z., & de Waal, F. (2013). Development of socio-emotional competence in bonobos. Proceedings of the National Academy of Sciences, 110(45), 18121-18126. https://doi.org/10.1073/pnas.1316449110

Social and emotional skills are tightly interlinked in human development, and both are negatively impacted by disrupted social development. The same interplay between social and emotional skills, including expressions of empathy, has received scant a... Read More about Development of socio-emotional competence in bonobos.

Bonobos Respond to Distress in Others: Consolation across the Age Spectrum (2013)
Journal Article
Clay, Z., & de Waal, F. B. (2013). Bonobos Respond to Distress in Others: Consolation across the Age Spectrum. PLoS ONE, 8(1), Article e55206. https://doi.org/10.1371/journal.pone.0055206

How animals respond to conflict provides key insights into the evolution of socio-cognitive and emotional capacities. Evidence from apes has shown that, after social conflicts, bystanders approach victims of aggression to offer stress-alleviating con...
