This chapter is the second of three (7–9) that focus on primate taxonomy, behavior, and biology. Whereas Chapter 7 discussed general primate characteristics, the present chapter deals with variation within the Order. The chapter begins with a discussion of the traditional primate suborders of prosimians and anthropoids (with discussion of alternative schemes). The monkeys are then reviewed, followed by discussion of hominoid characteristics, and a detailed survey of the living apes.
