These chimpanzees not only use these sticks to fish out their meal, but they in fact build their own 'tool kits' to do so, as observed in the Republic of Congo. They first use a smaller stick to break open the termite or ant mound, then use a large stick to make holes in the prey's colony, and then insert a 'fishing probe' into the hole and ...
Hominid apes build nests for sleeping at night, and in some species, for sleeping during the day. Nest-building by hominid apes is learned by infants watching the mother and others in the group, and is considered tool use rather than animal architecture. [1] [2] Neither Old World monkeys nor New World monkeys nest. [3]
Some of the most well-known tool use examples in chimpanzees include ant dipping, wood boring, honey fishing, leaf sponging, and nut-cracking. [57] 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]
The findings indicate the culture of the animals may be more similar to humans’ than often assumed.
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]
Tool making is much rarer, but has been documented in orangutans, [31] bonobos and bearded capuchin monkeys. Research in 2007 shows that chimpanzees in the Fongoli savannah sharpen sticks to use as spears when hunting, considered the first evidence of systematic use of weapons in a species other than humans.

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 ...
