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: A new study shows that chimpanzees possess a highly diverse culture of termite fishing that differs strongly among groups, with variation in community-specific combinations of elements parallels cultural diversity in human greeting norms or chopstick etiquette.

TL;DR: Chimpanzee terrestrial nocturnal activity appears widespread yet infrequent, which suggests a consolidated sleeping pattern, and it is suggested that chimpanzee noCTurnal activity is flexible, enabling them to respond to changing environmental factors.

TL;DR: In this paper, the authors analyzed a geographically comprehensive sample set amplified at microsatellite markers that inform recent population history and found that isolation by distance explains most of the range-wide genetic structure of chimpanzees.

TL;DR: The first non-invasive geolocalized catalog of genomic diversity by capturing chromosome 21 from 828 noninvasive samples collected at 48 sampling sites across Africa is presented in this article .
