Résumé : |
Culture has historically been considered a key characteristic of humanity. However, in recent decades research into culture in non-human animals has made remarkable progress. The Method of Exclusion(MoE) has been widely applied for the preliminary assessment of the occurrence of culture in many species, by identifying patterns of geographic variation in behaviour unexplained by ecological and genetic correlates and consistent with social learning. Among the great apes, the genus Gorilla hasbeen relatively understudied both in terms of social learning and culture. This study builds on the only assessment of cultural variation in gorillas by MoE through the addition of a population of western gorillas (Gorilla gorilla gorilla) in Gabon. The repertoire of gorillas was expanded from 23 to[...]
Culture has historically been considered a key characteristic of humanity. However, in recent decades research into culture in non-human animals has made remarkable progress. The Method of Exclusion(MoE) has been widely applied for the preliminary assessment of the occurrence of culture in many species, by identifying patterns of geographic variation in behaviour unexplained by ecological and genetic correlates and consistent with social learning. Among the great apes, the genus Gorilla hasbeen relatively understudied both in terms of social learning and culture. This study builds on the only assessment of cultural variation in gorillas by MoE through the addition of a population of western gorillas (Gorilla gorilla gorilla) in Gabon. The repertoire of gorillas was expanded from 23 to27 potential cultural behaviours through the reclassification of one environmental, one gestural and two foraging traits. An additional analysis of the cultural traits was made through a quantitative assessment of systematically recorded behaviours, revealing that some were more prevalent than previously thought. Our findings provide additional support that culture permeates all aspects of socio-ecology of great apes and that the MoE likely only scratches the surface of the true repertoire of culture in gorillas as for other species. Future efforts should not only focus on refining theme thods for the assessment of cultural diversity among individuals and populations, but also aim to bridge the knowledge gap in underlying social learning mechanisms. A greater understanding ofculture in non-human animals may help inform conservation strategies and provide insight into human evolution.
