Migrational Hypotheses

• Objective– Upon completion of this lesson students will be

able to identify 6 competing explanations of how humans migrated to the PNW.

Migrational Hypotheses

• Definitions– Migration

• Movement from one place to another. Includes emigration and immigration.

– Emigration• Movement OUT of a place with the intention of staying at the

destination. I emigrate FROM

– Immigration• Movement IN to a place with the intention of staying at the

destination. I immigrate TO

– Continental shelf• The relatively shallow ocean floor near the edges of a landmass (could

be exposed if much of the Earth’s water is frozen in glaciers)

Migrational Hypotheses

• Original Inhabitants– Native Americans were the first people to arrive in

the Pacific Northwest– Most likely came from Central Asia– 14,000 - 50,000 years ago

Migrational Hypotheses

• Six Hypotheses (p. 87)– Ice Bridge– Land Bridge– Continental Shelf– Kon Tiki– Ra– Continental Drift

Migrational Hypotheses

• Ice Bridge/Land Bridge/Continental Shelf– In common• During ice age• People walked from Asia to North America

Migrational Hypotheses

– Ice Bridge• Glaciers covered the Bering Strait• People walked across on glaciers

– Land Bridge• Also known as Beringia• Ocean lower, land exposed• People walked across on land

– Continental Shelf• No bridge• Edges of continents exposed• People walked along those edges

Migrational Hypotheses

• Kon Tiki and Ra II• Thor Heyerdahl– Primitive rafts made of logs, planks and ropes– Kon Tiki sailed 4,300 miles on Pacific Ocean from

Peru to Polynesian Islands– Ra II sailed from Morocco to Barbados– Implies people could have sailed from Asia to

North America

Kon Tiki – sailed from Peru to Polynesian Islands

Ra II – sailed from Morocco to Barbados

Sail from Central Asia to North America?

Migrational Hypotheses

• Continental Drift– Continents connected– They break apart – splitting human groups apart

• Problems:– No evidence of humans prior to 50,000 years ago– Continents drifted more than 1 million years ago

Migrational Hypotheses

• Work time– What should you be doing?– 1) Finishing your Coyote Tales essay (Due

tomorrow)– 2) Finishing Chapter Four vocabulary assignment– 3) Any other make-up work you may have
