Orangutans have larger gestural repertoires in captivity than in the wild—A case of weak innovation?

Summary: Whether nonhuman species can change their communicative repertoire in response to socio-ecological environments has critical implications for communicative innovativeness prior to the emergence of human language, with its unparalleled productivity. Here, we use a comparative sample of wild...

Here, we use a comparative sample of wild and zoo-housed orangutans of two species (Pongo abelii, Pongo pygmaeus) to assess the effect of the wild-captive contrast on repertoires of gestures and facial expressions. We find that repertoires on both the individual and population levels are larger in captive than in wild settings, regardless of species, age class, or sampling effort. In the more sociable Sumatran species, dominant use of signals toward single outcomes was also higher in captive settings. We thus conclude that orangutans exposed to more sociable and terrestrial conditions evince behavioral plasticity, in that they produce additional innate or innovated signals that are highly functionally specific. These findings suggest a latent capacity for innovativeness in these apes' communicative repertoires.Marlen FröhlichNatasha BartolottaCaroline FrynsColin WagnerLaurene MomonMarvin JaffrezicTatang Mitra SetiaCaroline SchuppliMaria A. van NoordwijkCarel P. van SchaikElsevierarticleWildlife behaviorZoo animal behaviorAnthropologyScienceQENiScience, Vol 24, Iss 11, Pp 103304- (2021)
