Chimpanzees in the Tai National Park only sometimes use tools, whereas Gombe chimpanzees rely almost exclusively on tools for their intake of driver ants. 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]
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.
Chimpanzees have used stone tools since at least 4,300 years ago. [141] A chimpanzee from the Kasakela chimpanzee community was the first nonhuman animal reported making a tool, by modifying a twig to use as an instrument for extracting termites from their mound. [142] [143] At Taï, chimpanzees simply use their hands to extract termites. [123]
One of the most important discoveries that was learned by observing the Kasekela chimpanzee community was the use of tools. On November 4, 1960, Goodall observed a chimpanzee that she had named David Greybeard using a grass stalk as a tool to extract termites from a termite hill. Later, she observed David Greybeard and another chimpanzee named ...
However, chimpanzees also use tools for accessing the bone marrow of other normally smaller non-human primates, [57] and even for medicinal purposes by swallowing leaves. [58] Chimpanzees are also capable of using two or more tools in a sequential order to achieve an end goal such as termite fishing or obtaining honey. [ 59 ]
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 ...
Goodall's research at Gombe Stream challenged two long-standing beliefs of the day: that only humans could construct and use tools, and that chimpanzees were vegetarians. [25] While observing one chimpanzee feeding at a termite mound, she watched him repeatedly place stalks of grass into termite holes, then remove them from the hole covered ...
Chimpanzee nest. Nest-building is seen in chimpanzees who construct arboreal night nests by lacing together branches from one or more trees. They can also build nap nests to rest in the afternoon, these are usually more poorly constructed than the night nests and can be built both on the ground and on the trees.
