Insights into human evolution from 60 years of research on chimpanzees at Gombe
Sixty years of research on chimpanzees (Pan troglodytes) at Gombe National Park, Tanzania have revealed many similarities with human behaviour, including hunting, tool use and coalitionary killing.The close phylogenetic relationship between chimpanzees and humans suggests that these traits were present in the last common ancestor of Pan and Homo (LCA PH).

African sanctuaries have emerged as an important context for research on chimpanzee cognition and behavior. We implemented a program of sanctuary observational data collection modeled after long-term data protocols at a wild chimpanzee site. This project can inform primate welfare, basic research questions in primatology, and support capacity ...
The Kibale Chimpanzee Project: Over thirty years of research
1.2. The challenge of chimpanzee conservation. Primates are among the most endangered of mammalian taxa, owing largely to the influence of deforestation and other human activities (Estrada et al., 2017).While chimpanzees face a less critical risk of extinction than some, they are endangered and their numbers are declining in the face of urgent conservation challenges, particularly as the ...

In this paper we use a continuous analysis of nonhuman primate social interactions (specifically, of chimpanzees) to show that, even in ego networks, the corresponding underlying structure is ...

How chimpanzees cooperate in a competitive world
Our earlier research demonstrated that chimpanzees are more likely to approach individuals close in rank to themselves at the apparatus . Our current results suggest that rank advantage played a role in both displacements and freeloading, indicating that the chimpanzees may have been pre-emptively avoiding competition by avoiding distantly ...

Here we assess the rate of population change for the western chimpanzee, Pan troglodytes verus, over a 24-year period. As a proxy for change in abundance, we used transect nest count data from 20 different sites archived in the IUCN SSC A.P.E.S. database, representing 25,000 of the estimated remaining 35,000 western chimpanzees.
Personality, cognition and behavior in chimpanzees: a new approach
Subjects and study site. The study sample consisted of 14 chimpanzees (Pan troglodytes), 9 males and 5 females, that ranged in age from 6 to 27 years (mean age ± SD = 17.71 ± 7.46 years) at the beginning of the study period.They were housed at Fundació Mona (Girona, Spain), a center dedicated to the rescue, rehabilitation and re-socialization of primates that have been previously used as ...
Chimpanzee vocal communication: what we know from the wild
Whilst chimpanzees communicate with vocal, gestural, facial, olfactory, and multimodal signals [39], vocalisations are particularly important since fission-fusion social dynamics and low-visibility natural habitats often mean group members are out-of-sight. Vocal communication is also critical and complex in many other primate and nonprimate ...

Author summary Viruses are a major factor driving recent and ongoing natural selection in mammalian genomes. Studying the effects such selection has had on chimpanzee genomes can provide valuable insights into how pathogens are affecting an endangered primate species. As there are many notable examples of cross-species transmission between other primates and humans—including the HIV/AIDS ...
The History of Chimpanzees in Biomedical Research
The use of chimpanzees in experimental biology and medical research expanded markedly in the late 1950s (Fridman and Nadler 2002) and was commensurate with the development of in-country national primate research centers and breeding colonies in the USA, Japan, UK, the Netherlands, Austria, and elsewhere.
Chimpanzee and Human Cultures
Two possible differences between the two species are discussed. First, thanks to indirect means of transmission such as language, cultural dissemination is possible over greater stretches of time and space in humans than in chimpanzees. Second, human cultures rely more intensively than chimpanzee cultures on cumulative cultural evolution ...
The Endangered Lab Chimp
In 1986, faced with increasing demands for chimpanzees from researchers studying the emerging AIDS epidemic, NIH started a breeding program. Numbers quickly grew, with the initial 315 male and female breeders producing nearly 400 offspring by 1997. But the chimpanzee AIDS model had problems from the get-go.
Chimpanzees' understanding of social leverage
Subjects. We tested 6 captive chimpanzees (1 female; M age = 14.6 years) housed at the Wolfgang Koehler Primate Research Center in Leipzig zoo (Table A in S1 File for more information about the apes that participated in the study). During the first phase of the study, the chimpanzees made up 3 unique pairs. In the second phase pairs were reshuffled to create 3 new pairs.
Chimpanzees in Research: Past, Present, and Future
U.S. Chimpanzee Research: 1920-1979. Chimpanzee research began with the work of Robert M. Yerkes of Yale University, who established a labo-ratory at his rural home in the early 1920s with two purchased chim-panzees (Yerkes and Learned 1925). His early writing about these animals, a male and a female, explored a wide range of behavioral

A Future of Hope: How Chimp Crazy Can Inspire Action for Primate
Hallmarks of Jane's activism in the U.S. alone include being a significant force in the efforts to list chimpanzees under the Endangered Species Act in the early 1990s, expanding those protections in 2013, and advocating for the near-total ban on biomedical research on chimpanzees in 2015.
Searching for the earliest archaeological record: insights from
For example, research conducted on western chimpanzees has revealed that the frequency of nut cracking depends on the proximity of suitable stones to fruiting nut trees [56-58]. This is because chimpanzees across long-standing field sites in West Africa are known to transport hammers and anvils short distances [19,45,59-62].

The chimpanzee (Pan troglodytes verus) community at Bossou in Guinea, West Africa, is particularly well suited for examining responses to human disturbances and pressures. It has been rated as the most heavily impacted long-term chimpanzee research site (Wilson et al.
