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.
Gorillas, the largest living primates, make their homes in central and east Africa. They function in a well-developed social structure and often exhibit behavior and emotions similar to the human experience, including laughter and sadness. Poaching, disease and habitat destruction remain threats for gorillas, and WWF is working to designate new protected areas where populations can thrive.
