Abstract Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the flexibility animals need for adapting to seasonal unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining influence of environmental variability on within-species diversity lacking despite critical assumption that population diversification precedes genetic divergence speciation. Here,...
More than just numbers We often frame negative human impacts on animal species in terms of individuals reduced or regions from which are absent. However, activities likely affecting more complex ways these figures can capture. Kühl et al. studied behavioral and cultural diversity our closest relative, the chimpanzee. They found that human-mediated disturbance is reducing traits. Human influence thus goes well beyond simple loss populations species, leading to change even where persist....
Abstract Teaching is a form of high-fidelity social learning that promotes human cumulative culture. Although recently documented in several nonhuman animals, teaching rare among primates. In this study, we show wild chimpanzees ( Pan troglodytes troglodytes) the Goualougo Triangle teach tool skills by providing learners with termite fishing probes. Tool donors experienced significant reductions use and feeding, while recipients significantly increased their feeding after transfers. These...
How populations adapt to their environment is a fundamental question in biology. Yet, we know surprisingly little about this process, especially for endangered species, such as nonhuman great apes. Chimpanzees, our closest living relatives, are particularly notable because they inhabit diverse habitats, from rainforest woodland-savannah. Whether genetic adaptation facilitates habitat diversity remains unknown, despite it having wide implications evolutionary biology and conservation. By...
The tool-using behaviors of wild chimpanzees comprise the most impressive assemblages and flexible repertoires nonhuman material culture. We expand knowledge breadth complexity tool use in this species by providing first descriptions form function two distinct sets used preying upon termites within forests Goualougo Triangle, Republic Congo. Further, we report application remote video monitoring technology to record chimpanzee behavior. Based on recovered at termite nests, hypothesized that...
Adopting the approach taken with New Caledonian crows ( Corvus moneduloides ), we present evidence of design complexity in one termite-fishing tools chimpanzees Pan troglodytes ) Goualougo Triangle, Republic Congo. Prior to termite fishing, applied a set deliberate, distinguishable actions modify herb stems fashion brush-tipped probe, which is different from form fishing used by East and West Africa. This means that ‘brush-tipped probes’, unlike ‘brush sticks’, are not by-product use but...
The emergence of technology has been suggested to coincide with scarcity staple resources that led innovations in the form tool-assisted strategies diversify or augment typical diets. We examined seasonal patterns several types tool use exhibited by a chimpanzee ( Pan troglodytes ) population residing central Africa, determine whether their technical skills provided access fallback when preferred food items were scarce. Chimpanzees Goualougo Triangle exhibit diverse repertoire behaviours,...

Identifying microbial pathogens with zoonotic potential in wild-living primates can be important to human health, as evidenced by immunodeficiency viruses types 1 and 2 (HIV-1 HIV-2) Ebola virus. Simian foamy (SFVs) are ancient retroviruses that infect Old New World monkeys apes. Although not known cause disease, these of public health interest because they have the humans thus provide a more general indication exposure risks. Surprisingly, no information exists concerning prevalence,...
Numerous protected areas (PAs) have been created in Africa to safeguard wildlife and other natural resources. However, significant threats from anthropogenic activities decline of populations persist, while conservation efforts most PAs are still minimal. We assessed the impact level common within tropical relationship with threat level. collated data on 98 forest cover 15 countries across West, Central East Africa. For this, we assembled information about local as well published unpublished...
We quantify the impacts of poaching, Ebola, and habitat degradation on western lowland gorillas central chimpanzees.
Several populations of wild chimpanzees use tools to raid bee nests, but preliminary observations in the Congo Basin indicate that they may have developed sophisticated technical solutions gather honey differ from those apes other regions. Despite lack habituated groups within range central subspecies, there been several reports different types used by open beehives and honey. Researchers observed some these behaviors (honey dipping) western eastern chimpanzees, whereas others (hive...
Abstract The study of the archaeological remains fossil hominins must rely on reconstructions to elucidate behaviour that may have resulted in particular stone tools and their accumulation. Comparatively, tool use among living primates has illuminated behaviours are also amenable examination, permitting direct observations leading artefacts assemblages be incorporated. Here, we describe newly discovered tool-use accumulation sites wild chimpanzees reminiscent human cairns. In addition data...

In this study, we compared using behaviours potential drivers these Wamba population located central Democratic Republic Congo with Goualougo chimpanzee northern Congo. The repertoire was...
Significance Understanding social influences on how apes acquire tool behaviors can help us model the evolution of culture and technology in humans. Humans scaffold novice skills with diverse strategies, including transfer tools between individuals. Chimpanzees tools, this behavior meets criteria for teaching. However, it is unclear task complexity relates to form helping. Here, we find differences 2 wild chimpanzee populations rate, probability, types during termite gathering. showed...
