TL;DR: It is shown that chimpanzees exhibit greater behavioural diversity in environments with more variability — in both recent and historical timescales, suggesting that environmental variability was a critical evolutionary force promoting the behavioural, as well as cultural diversification of great apes.

TL;DR: The ritualized behavioural display and collection of artefacts at particular locations observed in chimpanzee accumulative stone throwing may have implications for the inferences that can be drawn from archaeological stone assemblages and the origins of ritual sites.

TL;DR: The results support the view that “culturally significant units” should be integrated into wildlife conservation and show that chimpanzees inhabiting areas with high human impact have a mean probability of occurrence reduced by 88%, across all behaviors, compared to low-impact areas.

TL;DR: It is suggested that species-typical leadership styles and social and environmental effects, including familiarity with humans, best explain novelty responses of wild great apes and the feasibility of large-scale field experiments and the importance of both intrinsic and extrinsic factors in shaping animal curiosity.

TL;DR: A comprehensive molecular screening of all 9 African great ape species/subspecies, using 675 fecal samples collected from wild animals, identified CMVs in eight species/ subspecies and tested competing hypotheses with various degrees of co-divergence/number of host switches.
