For example, researchers have observed wild chimpanzees using fundamental foraging instruments, pestles, levers, utilizing leaves as sponges, and tree bark or vines as probes to fish termites. West African chimpanzees use stone hammers and anvils for cracking nuts, as do capuchin monkeys of Boa Vista, Brazil. Tool use just isn’t the one type of animal technology use; for instance, beaver dams, constructed with wooden sticks or giant stones, are a technology with “dramatic” impacts on river habitats and ecosystems. In physics, the invention of nuclear fission in the Atomic Age led to both nuclear weapons and nuclear power. Computers have been invented and later shifted from analog to digital within the Digital Revolution. Information technology, significantly optical fiber and optical amplifiers led to the birth of the Internet, which ushered within the Information Age.
