  1. EARLY HUMAN DEVELOPMENT A POWERPOINT PRESENTATION BY MR. SZETO

  2. Aim: How did modern humans develop? Do Now: Read Mary Leakey: Digger into the Past and answer the questions.

  3. Investigating About Prehistoric Peoples • Prehistory dates back to the time before the invention of writing. • Archaeologists, anthropologists and paleontologists are trained scientists to uncover the story of prehistoric peoples. This is done through: • Excavating archaeological digs • Studying and analyzing evidence such as bones and artifacts

  4. Mary Leakey Found Early Footprints • In 1978, Mary Leakey and a team found prehistoric footprints that resembled those of modern humans. • These footprints were made by australopithecines. Because they can walk upright, they are called hominids.

  5. HUMAN DEVELOPMENT • Australopithecines • 4 million to 1 million B.C. • Found in southern and eastern Africa • Brain size 500 cubic centimeters • First humanlike creature to walk upright (hominids) 4 million years ago 3 million years ago 2 million years ago 1 million years ago Present

  6. “Lucy” in the Earth • Anthropologist Donald Johanson discovered a complete skeleton of an adult female hominid, later named “Lucy”. • Lucy had lived around 3.5 million years ago – oldest hominid found to that date.

  7. Opposable Thumb • Early hominids had already developed the opposable thumb. • This means that the tip of the thumb can cross the palm of the hand.

  8. Paleolithic Age • Paleolithic Age or Old Stone Age, lasted from about 2.5 million to 8000 B.C. • Much of the Paleolithic Age occurred during the period in the earth’s history known as the Ice Age. The last Ice Age ended 10,000 years ago.

  9. HUMAN DEVELOPMENT • Homo habilis • 2.5 million to 1.5 million B.C. • Found in East Africa • Brain size 700 cubic centimeters • First to make stone tools 4 million years ago 3 million years ago 2 million years ago 1 million years ago Present

  10. Primitive knives and scarpers used during the Old Stone Age. Old Stone Tools

  11. HUMAN DEVELOPMENT • Homo erectus • 1.6 million to 30,000 B.C. • Found in Africa, Asia, and Europe • Brain size 1,000 cubic centimeters • First to migrate and use fire and develop spoken language 4 million years ago 3 million years ago 2 million years ago 1 million years ago Present

  12. HUMAN DEVELOPMENT • Neanderthal • 200,000 to 30,000 B.C. • Found in Europe and Southwest Asia • Brain size 1,500 cubic centimeters • Powerfully built, first to have ritual burials 4 million years ago 3 million years ago 2 million years ago 1 million years ago Present

  13. HUMAN DEVELOPMENT • Cro-Magnon • 40,000 to 8,000 B.C. • Found in Europe • Brain size 1,400 cubic centimeters • Remains identical to that of modern humans • Created art 4 million years ago 3 million years ago 2 million years ago 1 million years ago Present

  14. Summary/Application • Which advance by a hominid group do you think was the most significant? Explain. • What clues do bones and artifacts give about early peoples? • What were the major achievements in human history during the Old Stone Age? • How did Neanderthals and Cro-Magnons differ from earlier peoples? • Why was the discovery of fire so important? • Why will specific details about the physical appearance and the customs of early peoples never be fully known? • How do recent findings keep revising knowledge of the prehistoric past? • Explain which skill – tool making, the use of fire, or language – you think gave hominids the most control over their environment.
