The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees. Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 m (4 ft 1 in and 5 ft 11 in), weights between 100 and 270 kg (220 and 600 lb), and arm ...
