Chimpanzee

Chimpanzees are one of two species in the genus Pan of the family Hominidae (Great Apes), a family which includes gorillas, chimpanzees, orangutans, and humanoids. The common chimpanzee (Pan troglodytes) and the bonobo (Pan paniscus) are the two species of chimpanzee native to Earth. Sentient, highly-intelligent chimpanzees exist on at least one alternate Earth and the planet Haphaestus.

During James T. Kirk's first five-year mission, on an alternate Earth, Kirk met intelligent apes Cornelius, Zira, Doctor Zaius and others. There, Commander Kor conspired to make the local government more receptive to a Klingon alliance. .

In 2274, Kirk and Spock met the simian Hephaestans. Kirk described them in his log as “a friendly and intelligent, but naive, people.” They were not natively intelligent, however. A closely-guarded secret was that an unidentified alien race had visited Hephaestus ages earlier and provided them with subcutaneous symbiont chips that augmented their intelligence. They were taught how to manufacture the chips and surgically implant them over the base of the skull, done in a ritual shortly after birth. Klingon Captain Kagg of the IKS Kluggoth had discovered this, and plotted to destroy the Hephaestans’ manufacturing center and remove their chips, thus creating a planet with non-intelligent inhabitants which could be conquered without interference from the Organians.
