Document Summary
O the study of primates is to understand how different primates have adapted anatomically and behaviorally to their environments. O results of studies may help us to understand the behaviour and evolution of human primate. O all primates, including humans, evolved from their earlier primates that are now extinct. O all primates belong to the class mammalia- share common features of mammals. O except for humans they, the bodies of primates are covered with dense hair or fur- provides insulation. O almost all mammals give birth to offspring- develop in womb, nurse after birth. O all primates hind limbs are structured- support and feet grasp things. O orangutans- flexible hind limbs that can support themselves from, withstanding pulling/pushing. O hind limb- one bone in upper portion, two bones in lower portion. O double bone gives extensive mobility for rotating arms and legs. O clavicle/ collarbone- freedom of movement- shoulders: up/down, forward/back. O omnivores: eating both meat and vegetation (primates)
