A comparison of bonobo and chimpanzee tool use: evidence for a female bias in the Pan lineage (2010, unknown): “Chimpanzees are well known for their group- and population-specific behavioural differences (e.g. Whiten et al. 1999; Crockford et al. 2004) and, crucially, somechimpanzeegroupshardlyuse tools in thewild, despitedecades of long-term observations (Reynolds 2005).”
Learned vocal group signatures in the polygynous bat Saccopteryx bilineata (2012, background): “…in nonhuman mammals (bats: Boughman 1998; cetaceans: Tyack & Sayigh 1997; Watwood et al. 2004; Nousek et al. 2006; primates: Elowson & Snowdon 1994; Crockford et al. 2004; Snowdon 2009; ungulates: Briefer & McElligott 2012), thus adding to the growing body of evidence that social influences play…”
Minimal Requirements for the Emergence of Learned Signaling (2014, background): “De Vylder and Tuyls (2006) show that, as shown with simple conventions in Vylder (2008), convergence on a minimal, unambiguous, conventional lexicon is guaranteed if agents utilize a strongly amplifying imitation function (as described in Section 2).”
The evolution of the language faculty: clarifications and implications. (2005, background): “Although such bimanual sound making seems quite unusual among animals, this phenomenon has received surprisingly little study ( Arcadi, Robert, & Boesch, 1998; Schaller, 1963 ), and it seems premature to conclude, as PJ do, that rhythmfollowing is uniquely human, particularly on the dubious authori”
Contextual variation in chimpanzee pant hoots and its implications for referential communication (2005, result): “suggests that, at the very least, the calls must be acoustically distinctive between the members of different groups, and several studies have confirmed marked individual differences in the structure of pant hoots (Goodall 1968; Marler & Hobbett 1975; Bauer & Philip 1983; Mitani 1996) as well as con”
Vocal, gestural and locomotor responses of wild chimpanzees to familiar and unfamiliar intruders: A playback study (2009, unknown): “Interactions between neighbouring groups occur about once every 2 weeks and they are often limited to vocal exchanges, suggesting that individuals have considerable learning opportunities over time (Boesch & Boesch-Achermann 2000; Crockford et al. 2004).”
Did Neanderthals and other early humans sing? Seeking the biological roots of music in the territorial advertisements of primates, lions, hyenas, and wolves (2009, background): “Interestingly, chimps in closely neighbouring communities actively modify their pant hoots to create community-specific calls (Crockford et al., 2004).”
