• Agenda– Objective– Notes• Definitions• Six 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

– 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)

• 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

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

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

– 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

• 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
