How do apes differ from monkeys?
“Apes differ from monkeys in several ways. Apes have no tail and generally have a larger body weight than most other primates. They have a more upright body posture and a broad chest…. Apes rely more on vision than on smell and have a short broad nose rather than a snout, as Old World monkeys do. Apes have a larger brain relative to the body size than other primates do….” Rowe, Noel. The Pictorial Guide to the Primates. New York : Pogonias Press, 1996. P. 207.
