Learning target
Learning Target

  • I can explain how the new migration theory replaced the old migration theory.


The old migration theory
The Old Migration Theory

  • 200,000 – 100,000 yrs. ago Homo sapiens in Africa

  • 100,000 yrs. ago they migrated to Europe, the Middle East and Asia (the “Old World”)

  • 50,000 – 30,000 yrs. ago spread to most habitable “Old World”

  • Around 12,000 yrs. ago humans appeared in North and South America (“New World”)


The old migration theory1
The Old Migration Theory

  • From Asia to Alaska using a land bridge. That existed between 15,000 – 10,000 yrs. ago

    • Land bridge was created by lower sea levels during the last ice age


Criticism of old theory
Criticism of Old Theory

  • Archaeologists have found artifact on the East coast and in South America that are 50,000 – 20,000 yrs. old

  • Biologists are using skull and DNA testing to prove that the first New World humans come from a range of Old World locations

  • Language specialists say it would have taken 50,000 – 30,000 yrs. to develop our current language diversity


The kennewick man
The Kennewick Man

  • Found in 1996 in Kennewick, Washington

  • His skull and skeletal feature have more in common with people from Northern Japan than Central Asia

  • People came to the New World from different places, at different times, and in different ways


The new migration theory
The New Migration Theory

  • 35, 000 – 20,000 yrs. ago first people arrived in North America

  • Some used the land bridge while others crossed in small boats

  • A diverse group of people came to the New World at different times

    • Multiple migration stories
