Other animal species
Non-human animal species also make use of simple technology.For example, researchers have observed wild chimpanzees using basic foraging tools, pestles, levers, using leaves as sponges, and using tree bark or vines as probes to fish termites.
 West African chimpanzees use stone hammers and anvils for cracking nuts. Capuchin monkeys of Boa Vista, Brazil use stone hammers and anvils for cracking nuts.
 Tool use is not the only form of animal technology useOne example of a technology with “dramatic” effects on river habitats and ecosystems is the construction of beaver dams out of large stones or wooden sticks.
