Title: Topic: Early Human Migration


1
Topic Early Human Migration
Essential Question Why did early humans migrate
and how?
2
People on the Move
  • Old Stone Age (Paleolithic Era), the climate
    around the world began to change.
  • This also transformed the Earths geography
  • These changes forced people to migrate, or move,
    to new places
  • Early humans began this process as early as 2
    million years ago.

3
Ice Ages
  • Scientists believe the cause for this migration
    was long periods of freezing weather, called the
    ice ages.
  • During this time, huge ice sheets covered much of
    the Earth.
  • This period began about 1.6 million years ago and
    ended about 10,000 years ago.

4
More Ice Ages
  • The ice was formed from ocean water, which
    significantly lowered the ocean level.
  • Many areas that are underwater today were dry
    land as a result.
  • Strips of land that connected continents, or land
    bridges, to be exposed
  • This allowed hominids to travel to many
    continents.

Settling New Lands
  • Humans began to migrate from East to southern
    Africa
  • From there they spread out to Southeast Asia and
    Europe.
  • From there they could migrate to Australia.
  • However, it is still unclear as to how early
    hominids made it to Australia.

7
How Did We Get Here?
  • Land Bridge Theory
  • Most scholars believe that early humans crossed a
    land bridge from Asia to North America following
    herds of animals.
  • Coastal Theory
  • Humans followed the coasts either walking or in a
    simple boat.
  • Island Hopping Theory
  • Move between islands that are small distances
    apart until you reach your final destination.
    (Ex. Chains of islands in Indonesia to get to
    Australia)

8
Adaptations
  • Many of the new lands that humans migrated to had
    much colder climates.
  • There were also strange plants and animals that
    early humans had never seen before
  • In order to survive in their new homes, they had
    to adapt to their surroundings.

9
Clothing
  • Fire was used to keep people warm, however it was
    not enough.
  • People had to learn to sew animal skins together
    to make new warmer clothing.

10
Shelter
  • These people first took shelter in caves, but not
    all areas had caves to live in.
  • The first homes were called pit houses.
  • These were pits in the ground
  • with roofs of branches and leaves.
  • Above ground homes were also made.
  • Tents of animal skin.
  • Permanent structures made of wood, bones, stone,
    clay, etc.

Tools and Technology
  • New uses for bones and stone tools were
    discovered.
  • Fishing hooks and spears
  • First Bow and Arrows
  • New technology improved their lives.
  • Canoes
  • Pottery
