Transcript of "Humans and other primates"

  1. 1. Humans and Other Primates
  2. 2. Theories Most scientists agree that there is enough evidence to support the theory that humans, apes, and monkeys share a common ancestor Many fossils of organisms show traits of both humans and apes
  3. 3. Primates Primates: a group of mammals that includes humans, apes, monkeys, and lemurs  Have opposable thumbs (5 flexible fingers)  Have binocular vision (eyes are located on front of head and provide 3-D vision
  4. 4. First primates Ancestors of primates were mouse-like mammals that were active at night, lived in trees, and ate insects
  5. 5.  First primates did not exist until dinosaurs died out Chimpanzee is the closest living relative of humans  This doesn’t mean that humans descended from chimps  Means that humans and chimps had a common ancestor
  6. 6. Hominids Humans are in a family separate from other primates Hominids: includes only humans and their human-like ancestors Main characteristic that separates hominids from other primates is bipedalism walking up right on two feet
  7. 7. Hominids Through Time Scientists have named at least 18 types of hominids Earliest hominids  Ability to walk upright, smaller teeth, flatter faces, larger brains that earlier primates  Oldest hominid fossils have been found in Africa
  8. 8. Australopithecines  Members of this group were similar to apes but different in several ways  Some may have used stone tools  Climbed trees, but walked on two legs
  9. 9. Variety of Early Hominids Global Hominids  About 2.3 million years ago, new group of hominids appeared  Larger and more complex brains, rounder skulls, and flatter faces that earlier hominids  Showed advanced tool-making abilities  Walked upright
  10. 10.  Members of group Homo, which includes modern humans (Homo Sapiens) Early member of this group was Homo hablis, which lived 2 million year ago Homo erectus appeared a million years later and grew as tall as modern humans
  11. 11. Recent Hominids As recently as 30,000 years ago, two types of hominids may have lived in the same areas at the same time Both had largest brains of any hominid More advanced tools, clothing, and art Modern humans may have descended from one of these two types of hominids
  12. 12.  Neanderthals  Lived in Europe and western Asia  Hunted large animals, made fires, and wore clothing  Disappeared 30,000 years ago and no one knows what caused their extinction
  13. 13.  Early and Modern Humans  Modern humans are classified as Homo sapiens  Earliest group existed in Africa Of all known hominids, only Homo sapiens exist  Seem to be the first to create art
