Gorillas are the largest of the living primates. They are ground-dwelling and predominantly herbivorous, inhabiting the forests of central Africa. Gorillas are divided into two species and (still under debate as of 2008) either four or five subspecies. The DNA of gorillas is 98%-99% identical to that of a human, and they are the next closest living relatives to humans after the two chimpanzee species. (Wikipedia) Gorillas have been ethnoknown possibly as far back as c. 480 BC, and were discovered to be real animals in 1847.
