  1. Ms. Carmelitano Peopling of the World Prehistory – 2500 BC

  2. If the present is “midnight” what “time” do you think human beings came into being? Imagine the whole history of the earth as a 24-hour clock

  3. Little is known about early human species because they had no writing • Historians call this time pre-history • Instead of studying written records, scientists study: • Fossils • Bones • Artifacts: Human-made objects • Tools • Jewelry Studying the past

  4. Where it all began

  5. It was once believed that the “birth place” of the human species was Asia • In the 1930’s that all changed! • Louis S. B. Leakey • Believed Africa was the birth place of humans • In the 1930’s he found fossil evidence of human beings in Sub-Saharan Africa; Tanzania The Early Human

  6. Tanzania Africa Map

  7. Mary Leakey 1978 • Found prehistoric footprints that resembled those of modern humans in volcanic ash in Tanzania • (Homo Habilis) The Early Human

  8. Anthropologist Donald Johanson studied in Ethiopia • 1974 – Discovered a complete skeleton of an adult female hominid (Australopithecus) • Lived 3.5 million years ago • Oldest, most complete hominid found to that date The Discovery of “Lucy”

  9. Evolution • A gradual process in which something changes into a different and usually more complex or better form The Evolution of Humans

  10. The Evolution of Humans

  11. Human evolution: the process of change by which people originated from apelike ancestors. • Hominid – A human that walks upright (on 2 feet) • Lucy and the Leaky footprints came from Hominids, they walked on two feet • Bipedalism – or the ability to walk on two feet The Evolution of Humans

  12. Physical and behavioral traits shared by all people originated evolved over a period of six million years. • human traits: • bipedalism • large and complex brain • ability to make and use tools • capacity for language • complex symbolic expression, art, and elaborate cultural diversity Traits of Humans

  13. The first eras of human existence can be separated into two sections • Paleolithic: Old Stone Age from 2.5 million to 8000 B.C. • Hominid Species first emerged • Hominid Species began to use stone tools intelligently • Fire is discovered (Homo-Erectus) • Mesolithic: Middle Stone Age • Homo Sapiens first emerged • Advance in the use of stone tools Human Eras

  14. Australopithecus • Existed: 4 million BCE • Homo Habilis • 2.5 million B.C.E • B.C.E. – means ‘before common era’ • C.E. or A.D. – means ‘common era’ • Homo: Human • Homo-Erectus: • Existed 1.6 million BCE • “Upright man” Paleolithic – the first People

  15. Homo Sapiens: • “wise man” • Modern Humans • The first Homo-sapiens evolved in Africa 100,000 and 400,000 years ago • Homo Sapiens: Neanderthal • 200,000-30,000 BCE • Homo Sapiens Cro-Magnon • 40,000-8,000 BCE Mesolithic Period
