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: Analysis of the largest survey dataset ever assembled for forest elephants revealed that population size declined by ca.

TL;DR: In this paper, the authors used the same stimulus for diverse racial groups (Bakossiland, Cameroon, Africa; Komodo Island, Indonesia; Samoa; and New Zealand) to examine the universality of relationships between waist-hip ratio (WHR) and attractiveness.

TL;DR: In this article, the authors used a maximum entropy algorithm and logistic regression to predict the distribution of suitable environmental conditions (SEC) for eight African great ape taxa for a first time period, the 1990s and then project it to a second time period (the 2000s) to assess the relative importance of factors influencing SEC distribution and to estimate rates of SEC loss, isolation and fragmentation over the last two decades.

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.
