  • Chimpanzee alarm call production meets key criteria for intentionality 

    Schel, Anne Marijke; Townsend, Simon W.; Machanda, Zarin; Zuberbuehler, Klaus; Slocombe, Katie E. (2013-10-16) - Journal article
    Determining the intentionality of primate communication is critical to understanding the evolution of human language. Although intentional signalling has been claimed for some great ape gestural signals, comparable evidence ...
  • A cognitive approach to the study of culture in wild chimpanzees (Pan troglodytes schweinfurthii) 

    Gruber, Thibaud (University of St Andrews, 2011-11-30) - Thesis
    The question of animal culture has been of interest for decades. Chimpanzees (Pan troglodytes) have played a key role in the debate of whether or not it is appropriate to use the term ‘culture’ to describe animal behaviour ...
  • Experimental field studies with non-human primates 

    Zuberbuehler, Klaus (2014-10) - Journal article
    One way to study language evolution is to compare human communication with closely related non-human primate species. This comparative approach has turned to be especially productive if subjects are studied under natural ...
  • Gestural communication of the gorilla (Gorilla gorilla) : repertoire, intentionality, and possible origins 

    Genty, Emilie Juliette Pauline; Breuer, Thomas; Hobaiter, Catherine Louise; Byrne, Richard William (2009-05) - Journal article
    Social groups of gorillas were observed in three captive facilities and one African field site. Cases of potential gesture use, totalling 9,540, were filtered by strict criteria for intentionality, giving a corpus of 5,250 ...
  • Mineral acquisition from clay by Budongo Forest chimpanzees 

    Reynolds, Vernon; Lloyd, Andrew W.; English, Christopher J.; Lyons, Peter; Dodd, Howard; Hobaiter, Catherine; Newton-Fisher, Nicholas; Mullins, Caroline; Lamon, Noemie; Schel, Anne Marijke; Fallon, Brittany (2015-07-28) - Journal article
    Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of ...
  • Predicting the vulnerability of great apes to disease : the role of superspreaders and their potential vaccination 

    Carne, Charlotte; Semple, Stuart; Morrogh-Bernard, Helen; Zuberbuehler, Klaus; Lehmann, Julia (2013-12-27) - Journal article
    Disease is a major concern for the conservation of great apes, and one that is likely to become increasingly relevant as deforestation and the rise of ecotourism bring humans and apes into ever closer proximity. Consequently, ...
  • Prestige affects cultural learning in chimpanzees 

    Horner, Victoria; Proctor, Darby; Bonnie, Kristin E.; Whiten, Andrew; de Waal, Frans B. M. (2010-05-19) - Journal article
    Humans follow the example of prestigious, high-status individuals much more readily than that of others, such as when we copy the behavior of village elders, community leaders, or celebrities. This tendency has been declared ...
  • Synchrony and motor mimicking in chimpanzee observational learning 

    Fuhrmann, Delia; Ravignani, Andrea; Marshall-Pescini, Sarah; Whiten, Andrew (2014-06-13) - Journal article
    Cumulative tool-based culture underwrote our species' evolutionary success, and tool-based nut-cracking is one of the strongest candidates for cultural transmission in our closest relatives, chimpanzees. However the social ...
