Stone Age: Aspects of Technology

  • Theme: Stone Age encompasses material form (hardware) and information form (software)
  • Periodization of history used in the material:
    • Ancient Times
    • The Middle Ages
    • Early Modern Era
    • Late Modern Era to Contemporary
  • Stone Age time period
    • Began at the dawn of human civilization and ends with the discovery of smelting
    • Smelting led to metal tools, causing stone tools to become obsolete
    • Migration out of Africa to Eurasia, Australia, and the Americas (theory and evidence points to these routes)
  • Stone Age periods
    • Paleolithic
    • Neanderthals and Cro‑Magnons lived during this period
    • Early humans as hunter–gatherers
    • Used early stone tools with a single sharp edge
    • cave art depicted life
    • Mesolithic
    • Developed needles and thread for animal-skin clothes
    • Controlled fire and language development
    • Migrations out of Africa continued
    • Neolithic
    • Homo sapiens only; no other hominins mentioned in this period here
    • Polished stone tools and pottery development
    • Transition from hunting/gathering to animal husbandry and agriculture
  • Stone Age tools
    • Created to aid survival: hunting, farming, food prep
    • Made from different stones
  • Stone Age technology (inventories and functions)
    1. Fire: controlled environment and adaptation
    2. Wheel: movement efficiency; early wheels used for pottery; later for chariots/transport
    3. Flint knapping: shaping stones by edge creation; flakes chipped to form sharp edges
    4. Atlatl: spear-throwing advancement; increased range and impact; helped hunting dangerous game
    5. Bow and arrow: longer-range hunting and safety
    6. Clothing: animal pelts used as garments (skin and fur attached)
    • Page 2 note: waterproofing and processing limitations (long preparation: hair removal, washing, drying, stretching)
    1. Boat: marine transport, hunting; typical in colder environments; limitations for long-distance travel
    2. Pottery: Neolithic development; storage of food; facilitated sedentary life and civilization groundwork
  • Civilization foundation
    • Stone Age laid the groundwork for all civilizations; history can be viewed as a continuum of Stone Age discoveries
