Wild chimpanzees regularly use tools, made from sticks, leaves, or stone, to find flexible solutions to the ecological challenges of their environment. Nevertheless, some studies suggest strong limitations in the tool‐using capabilities of chimpanzees. In this context, we present the discovery of a newly observed tool‐use behavior in a population of chimpanzees (Pan troglodytes verus) living in the Bakoun Classified Forest, Guinea, where a temporary research site was established for 15 months…

Chimpanzees foraging on aquatic foods: algae scooping in Bossou
TLDR
A detailed description of this unique behavior is provided and contextualize it within the current knowledge of the exploitation of aquatic foods by apes in forest environments.
Crab-fishing by chimpanzees in the Nimba Mountains, Guinea.
DNA recovery from wild chimpanzee tools
TLDR
The utility of bio-molecular techniques and a primate archaeology approach in non-invasive monitoring and behavioural reconstruction of unhabituated primate populations is demonstrated.
Landscaping the behavioural ecology of primate stone tool use
TLDR
The findings indicate that the technological landscape of the Bossou chimpanzees shares affinities with the ‘favoured places’ model of hominin site formation and provides new insights for reconstructing ancient patterns of landscape use.
Limited evidence of C4 plant consumption in mound building Macrotermes termites from savanna woodland chimpanzee sites.
TLDR
Macrotermes consumption is unlikely to result in high carbon isotope values in either extant chimpanzees or fossil hominins, according to the isotope signatures of consumers.
Bili-Uéré: A Chimpanzee Behavioural Realm in Northern Democratic Republic of Congo
TLDR
A new chimpanzee behavioural complex is proposed, characterised by a general similarity of multiple behaviours across a large, ecologically diverse region but with subtle differences in prey choice and techniques, referred to as the Bili-Uéré Chimpanzee Behavioural Realm.
Nocturnal activity in wild chimpanzees (Pan troglodytes): Evidence for flexible sleeping patterns and insights into human evolution.
TLDR
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.
Quantitative estimates of glacial refugia for chimpanzees (Pan troglodytes) since the Last Interglacial (120,000 BP)
TLDR
Using bioclimatic variables representing monthly temperature and precipitation estimates, past human population density data, and an extensive database of georeferenced presence points, a model of changing habitat suitability for chimpanzees is built at fine spatio‐temporal scales dating back to the Last Interglacial.
Landscapes of the apes: modelling landscape use of chimpanzees and early hominins across an environmental gradient.
As primate habitat is declining rapidly, studying the flexibility of primates to adapt to changing landscapes is important. Landscape-scale studies of primate habitat use are, however, scant.…
Late Quaternary habitat suitability models for chimpanzees (Pan troglodytes) since the Last Interglacial (120,000 BP)
TLDR
The first fine-grained dynamic map of historical chimpanzee habitat suitability since the Last Interglacial is provided, suspected to have influenced a number of ecological-evolutionary processes, such as the emergence of complex patterns of behavioural and genetic diversity.

TLDR
Recent findings from nature are reviewed, focusing on those with direct implications for hominin evolution, e.g. apes, using elementary technology to access basic resources such as food and water, or sheltering in caves or bathing as thermoregulatory adaptations.
Chimpanzee accumulative stone throwing
TLDR
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.

The Tool Repertoire of Bossou Chimpanzees

This chapter aims to present globally the Diversity of tool-use behaviors of the Bossou chimpanzees, highlighting their age-class, sex, and temporal distribution, the diversity of domains in which they are observed, and patterns of hand use during tool manipulation.
Cultures in chimpanzees
TLDR
It is found that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted.
Shallow-water habitats as sources of fallback foods for hominins.
TLDR
This study differs from traditional savanna chimpanzee models of hominin origins by proposing that access to aquatic habitats was a necessary condition for adaptation to savanna habitats, and raising the possibility that harvesting efficiency in shallow water promoted adaptations for habitual bipedality in early hominins.
The conditions for tool use in primates: implications for the evolution of material culture.
TLDR
It is concluded that strong mutual tolerance was a key factor in the explosive increase in technology among hominids, probably intricately tied to a lifestyle involving food sharing and tool-based processing or the acquisition of large, shareable food packages.
