Title: The First Americans


1
The First Americans
  • Who were they?
  • How did they get here?
  • When did they arrive?
  • Where did they come from?

2
How did they arrive in the Americas?What are the
theories?
3
Beringia Land Bridge Theory Long-standing story
of their arrival in the Americas
4
Why would they cross Beringia?
  • Cold and arid, Beringia was clothed in the hardy
    grasses, herbs, dwarf birch and willows of the
    Mammoth Steppe.
  • This plant life supported such extinct species
    as the woolly mammoth, the mastodon, the steppe
    bison,  the giant beaver, the North American
    horse, and camel.

5
Need to Know
Thousands of years ago, people traveled
following herds of animals to the Americas
These people eventually developed into cultures
throughout North and South America As time
progressed these peoples lives changed
dramatically when the Europeans reached Americas
6
When could they have crossed?
It is theoretically possible for people to have
entered North America from Asia at repeated
intervals between 40,000 and 13,000 years ago.

How did they cross?
  • ? Because ice takes water from the ocean, the
    sea level dropped, allowing land to show that
    would normally be underwater
  • ? In the north, there is a land bridge which
    connects Siberia in Asia to Alaska in North
    America
  • ? The hunters spread throughout the land looking
    for better hunting grounds
  • ? They spread through North America, Central
    America, and South America

  • Earlier by boat along the Pacific Coast? (Coastal
    Theory)
  • Across the Atlantic? (Solutrean Theory)
  • From Africa?(Luzia)
  • Across the Pacific from Japan, Polynesia, or
    Australia?
  • Beringia then down the coast along the ice using
    boats occasionally?

Luzia may support an African origin for some
First Americans! Arriving earlier than previously
thought.
