Portrayals of wild primates in documentary films: Reason for concern?
Dexterity and technique in termite fishing by chimpanzees ( Pan troglodytes troglodytes ) in the Goualougo Triangle, Republic of Congo
Although the phenomenon of termite fishing by chimpanzees ( Pan troglodytes ) has historical and theoretical importance for primatology, we still have a limited understanding of how chimpanzees accomplish this activity, and in particular, about details of skilled actions and the nature of individual variation in fishing techniques. We examined movements, hand positions, grips, and other details from remote video footage of seven adult and subadul…
Fermented food consumption in wild nonhuman primates and its ecological drivers
OBJECTIVES: Although fermented food use is ubiquitous in humans, the ecological and evolutionary factors contributing to its emergence are unclear. Here we investigated the ecological contexts surrounding the consumption of fruits in the late stages of fermentation by wild primates to provide insight into its adaptive function. We hypothesized that climate, socioecological traits, and habitat patch size would influence the occurrence of this beha…
Teaching Anthropology with Primate Documentaries: Investigating Instructors' Use of Films and Introducing the Primate Films Database
Nonhuman primate appearance and behavior can be better understood through documentary footage than through verbal explanation alone. Many college instructors show primate documentary films in their courses, but little research has evaluated primate documentaries as teaching tools. We sought to determine the prevalence of documentary use in teaching and which characteristics of documentaries affect their use. An online survey queried 219 college-l…
Lateralization and performance asymmetries in the termite fishing of wild chimpanzees in the goualougo triangle, republic of Congo
The nearly universal right hand preference manifested by human populations is one of the most pronounced manifestations of population-level lateralization. Morphological and archeological evidence indicate that this behavioral specialization may have emerged among our hominin ancestors. Whether population-level behavioral asymmetries are evident in non-human animals remains a topic of considerable scientific debate, with the most consistent evide…
The Interdigital Brace and Other Grips for Termite Nest Perforation by Chimpanzees of the G oualougo T riangle, R epublic of C ongo
Studies of chimpanzee termite foraging enlighten our understanding of early hominin tool use not only by modeling the cognitive ability of our ancestors but also by emphasizing the possible role of social insects in the hominin diet. The chimpanzees of the Goualougo Triangle are known to have one of the largest and most complex tool repertoires reported for wild chimpanzees. One tool set habitually used by this population includes a perforating t…
Insect prey characteristics affecting regional variation in chimpanzee tool use
Tool Use in Animals: Cognition and Ecology
The Role of Terrestriality in Promoting Primate Technology
Complex technology" has often been considered a hallmark of human evolution. However, recent findings show that wild monkeys are also capable of habitual tool use. Here we suggest that terrestriality may have been of crucial importance for the innovation, acquisition, and maintenance of "complex" technological skills in primates. Here we define complex technological skills as tool-use variants that include at least two tool elements (for example,…
Chimpanzees prey on army ants with specialized tool set
Several populations of chimpanzees have been reported to prey upon Dorylus army ants. The most common tool‐using technique to gather these ants is with “dipping” probes, which vary in length with regard to aggressiveness and lifestyle of the prey species. We report the use of a tool set in army ant predation by chimpanzees in the Goualougo Triangle, Republic of Congo. We recovered 1,060 tools used in this context and collected 25 video recordings…
Flexible and Persistent Tool-using Strategies in Honey-gathering by Wild Chimpanzees
Several populations of wild chimpanzees use tools to raid bee nests, but preliminary observations of chimpanzees in the Congo Basin indicate that they may have developed sophisticated technical solutions to gather honey that differ from those of apes in other regions. Despite the lack of habituated groups within the range of the central subspecies, there have been several reports of different types of tools used by chimpanzees to open beehives an…
