Basic Facts About Gorillas. Closely linked by DNA, gorillas (family Hominidae) are one of the four species of great apes that are the closest living relatives of humans â the other three are chimpanzees, bonobos and orangutans.
The gorilla is a heavily built primate and is the largest of the living apes. Western and eastern gorillas are more genetically distant from one another than are chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). Western gorillas live in lowland, swamp, and montane forests from sea level to 1600 m.
