Unlike other mammals, human hair growth and shedding is random and not seasonal or cyclical. At any given time, a random number of hairs will be in one of three stages of growth and shedding: anagen, catagen, and telogen. Anagen. Anagen is the active phase of the hair. The cells in the root of the hair are dividing rapidly. A new hair is formed and pushes the club hair (a hair that has stopped growing or is no longer in the anagen phase) up the follicle and eventually out. During this phase the hair grows about 1 cm every 28 days. Scalp hair stays in this active phase of growth for two to six years. Some people have difficulty growing their hair beyond a certain length because they have a short active phase of growth. On the other hand, people with very long hair have a long active phase of growth.

Depending on the terrain of their natural habitat, monkeys live in trees or on the ground. In the ecology of the rainforest, the species plays a very vital role in dispersion of seed. Most monkeys avoid wetlands, but are good swimmers.he 'Cercopithecoid' or 'Platyrrhine' primate that is a common sight today, belongs to the simian primate groups, smaller and longer-tailed than apes. Advertisement. Monkeys belong to the parvorders Platyrrhini and Catarrhini. This makes the mammal paraphyletic, without any distinct coherent group.
