Document Summary
Chimpanzees, gorillas, and orangutans are not monkeys they"re apes. One way to understand any organism is to compare its anatomy and behaviour with that of other, closely related species. This comparative approach helps explain how and why physiological and behavioural systems evolved as adaptive responses to various selective pressures throughout the course of evolution. Each lineage or species has come to possess unique qualities that make it better suited to a particular habitat and lifestyle. Primates are members of the mammalian order primates, which include lemurs, lorises, tarsiers, monkeys, apes, and humans. Anthropoids are members of the primate infraorder anthropoidea. Traditionally, this group includes monkeys, apes, and humans. Primates share many characteristics with other mammals, basic mammalian traits are: A relatively long gestation period followed by live birth. Different types of teeth (incisors, canines, premolars, and molars) The ability to maintain a constant internal body temperature through physiological means (endothermy) A considerable capacity for learning and behavioural exibility.
