Outline for Primate EvolutionI. Types of Primates A. New World shirk 1. Examples Spider Monkeys, Golden Lion Tamarins, and Squirrel Monkeys. 2. Diet usually consists of fruit, insects, and other minor(ip) animals 3. Very Diverse in size and ecology 4. Uses tail as a fifth limb to help ascent 5. First modern anthropoids to evolve 6. Successfully crossed the Atlantic naval 1. Either by rafting on floating Islands or by hybridisation bridges when sea level was low B. Old World Monkeys 1. Examples Mandrills, torso Monkeys, Grey Langurs and Baboons 2. Natives of Africa and Asia 3. They mostly live in Trees 4. They are mostly commonly known as cold weather monkeys. C. Apes 1. There are 5 genera of apes Gorillas, Chimpanzees, Gibbons, Orangutans, and Siamangs. 2. They are most commonly recognized as Primates without tails. 3. They excessively have very large brains. 4. Their diet consists of vegetables and other plant life. 1. Chimps from time to time have been observed killing other animals for food. 5. Apes are subject to the like disease as humans. 6. They can also use tools and sign language. D. Prosimians 1. Examples Lemurs and reversal Lemurs 2. Small tree dwelling primates 3. They are the size of a mouse to a large house cat. 4. Due to lack of facial nerve Muscles they cannot make facial changes that other primates use to communicate. II. Human course A. Bipedal 1. Since apes were pushed out of the trees by lack of food, they eventually had to adapt to manner of walking around on two legs. 2. Since their arms were free from walking on two legs, they could now use them to use tools. B. Hominids 1. A humanlike, bipedal Primate. 2. feature both ape and human characteristics. 3. Raymond Dart discovered a dodo skull that had an apelike braincase and face, but was unlike any primate he had ever seen. C. Australopithecine 1. Early Hominid that lived in Africa. 2. Most discipline gathered about the Australopithecine was first discovered by Donald Johnson . 1. Lucy draft a. First ever Australopithecine skeleton b. Lucy was classified as genus Australopithecus afarenis. c. Named after a song by the British pop crowd The Beetles. D. Australopithecus afarenis 1. Earliest known hominid species. 2. Fossils of its pelvis, legs, and feet indicate that it was bipedal, like humans. 3. Its cranium suggested an apelike brain. 1. Along with its shoulders and forelimbs.
