Document Summary
Using their upper limbs to move from tree limb to tree limb. Primates have long growth and development periods. Lemurs and macaques have the shortest growth period. The longer growth period reflects the greater behavioral complexity in apes and humans than in lemurs and macaques. This group consists of an adult male, and adult female, and their immature offspring. Primates form various social relationships for the long term. Less competition for females and thus little sexual dimorphism. Each partner"s reproductive success is tied to that of the other, and the male invests a relatively large amount of time and energy in the young. Gibbons, siamangs, two ceboids, and several species of strepsirhines practice this form of society. Lemurs and lorises having a grooming claw on the second toe. Hand clasp grooming, this distinctive type of grooming depicted here has been observed only in groups of chimpanzees in tanzania.
