This may be due to difference in the rewards gained by tool use: Gombe chimpanzees collect 760 ants/min compared to 180 ants/min for the Tai chimpanzees. [25] Some chimpanzees use tools to hunt large bees (Xylocopa sp.) which make nests in dead branches on the ground or in trees. To get to the grubs and the honey, the chimpanzee first tests for ...

One troop of chimpanzees may exhibit a learned behavior unique from another troop of chimpanzees, such as various tool usage. Some chimpanzee troops have been observed consuming aspilia , [ 1 ] for medicinal purposes, because it has been seen to remove intestinal parasites, and is otherwise unpalatable.
Chimpanzees, gorillas, orangutans, capuchin monkeys, baboons, and mandrills have all been reported as using tools. The use of tools by primates is varied and includes hunting (mammals, invertebrates, [29] fish), collecting honey, [30] processing food (nuts, fruits, vegetables and seeds), collecting water, weapons and shelter.
Recent research indicates that chimpanzees' use of stone tools dates back at least 4,300 years (about 2,300 BC). [60] One example of chimpanzee tool usage behavior includes the use of a large stick as a tool to dig into termite mounds, and the subsequent use of a small stick altered into a tool that is used to "fish" the termites out of the ...
Chimpanzees have been known to use tools for as long as they have been studied. Andrew Whiten found that chimpanzees not only use tools, but also conform to using the same method as the majority of individuals in the group. [53] This conformity bias is prevalent in human culture as well and is commonly referred to as peer pressure. [citation ...
The use of tools by this wide range of non-human primate taxa also provides data in the reconstruction of the different environmental, anatomical, behavioral and/or genetic factors that could lead to the emergence and subsequent evolution of stone tool manufacture and use across different species.
Started in 1978, it is one of the longest running laboratory research projects on chimpanzee intelligence. Matsuzawa has been a part of the project since the beginning. Matsuzawa has also studied tool use in the wild chimpanzees at Bossou, Guinea, West Africa since 1986. The bossou chimpanzee community consists of about 12 individuals and has ...
