Diet usually consists of fruit, insects, and other sensitive animals 3. Very Diverse in size and ecology 4. Uses tail as a fifth limb to help get up 5. First modern anthropoids to evolve 6. Successfully crossed the Atlantic marine 1. Either by rafting on floating Islands or by fording bridges when sea level was low B. Old World Monkeys 1. Examples Mandrills, automobile trunk Monkeys, Grey Langurs and Baboons 2. Natives of Africa and Asia 3. They mostly live in Trees 4. They are mostly unremarkably known as cold weather monkeys. C.

Since apes were pushed out of the trees by lack of food, they eventually had to adapt to 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 fogy 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.

Lucy was classified as genus Australopithecus afarenis. c. Named after a song by the British pop separate 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 braincase suggested an apelike brain. 1. Along with its shoulders and forelimbs.
