Primates have evolved through primate evolution from the beginning. Each primate has different characteristics for millions of years. At this stage the ecosystem has undergone major changes. The majority of the major changes are due to continental drift. Other factors include deforestation, natural disasters, and recently global warming. Due to these changes, primates are less growing in trees and more species. In order to survive under pressure of natural selection, life on earth and other factors, the primates have developed more upright movement, body structure change, body size increase and hair loss.
A primate (/ praɪme / t / (listen) PRY-mayt) is a primate mammal. In taxonomy, primates contain two different strains, streptomycin and haprolin. Primates are derived from ancestors living in trees of tropical forests; the characteristics of many primates represent living in this difficult environment. Most primate species are at least partially tree-grown. With the exception of humans living on all continents, most primates live in the tropical or subtropical regions of America, Africa and Asia. They are only 30 grams (1 ounce) in size from Madame Belt's rat lemur to Eastern gorilla and weigh more than 200 kilograms (440 pounds).
Primates evolved from trees of animals, many of which in most cases lived in trees. Most primates live in the rain forest. The number of primate species in the tropics has been shown to be positively correlated with rainfall and tropical rainforest area. It occupies (by weight) 25 to 40% of fruit animals in the rainforest, and primates play an important ecological role by dispersing seeds from many species. Some species are partially terrestrial, like baboons and patties, and some species are completely terrestrial like Jerada and man. Nonhuman primates live in the habitats of various forests in the tropical regions of Africa, India, Southeast Asia, South America, such as tropical rain forests, mangroves, mountain forests.
