Updated April 11, 2019. The Pacific Coast Migration Model is a theory concerning the original colonization of the Americas that proposes that people entering the continents followed the Pacific coastline, hunter-gatherer-fishers traveling in boats or along the shoreline and subsisting primarily on marine resources.
What is the coastal migration theory and why is it significant?
The coastal migration hypothesis has been bolstered by findings such as the report that the sediments in the Port Eliza caves on Vancouver Island indicate the possibility of a survivable climate as far back 16 ka (16,000 years) in the area, while the continental ice sheets were nearing their maximum extent.
What is the coastal route theory and what evidence supports it?
Archaeological discoveries show early human settlement along the northwest coast, and archaeological discoveries at inland sites show human occupation much earlier than the ice free corridor. Used together, this evidence supports a coastal human migration instead of an inland route into North America.
What is the difference between the land bridge theory and the coastal route theory?
The land-bridge theory started between 10,000 and 100,000 years ago when much of the world was covered by glaciers. The world’s water froze and the level of the oceans dropped. Areas that were once were covered by shallow water became dry land. … This idea was known as the coastal-route theory.
What is the Clovis First theory?
The Clovis First hypothesis states that no humans existed in the Americas prior to Clovis, which dates from 13,000 years ago, and that the distinct Clovis lithic technology is the mother technology of all other stone artifact types later occurring in the New World.
How does the kelp highway relate to the coastal migration theory?
The kelp highway theory suggests that the first Americans arrived not by land, but by sea, following the coastline of the Pacific Rim of northeastern Asia and Beringia to as far south as South America.
Why is the second migration theory called the Pacific coastal theory?
This theory postulates that the people of Beringia crossed a land bridge about 13,500 years ago, when sea levels were much lower worldwide due to the earth’s latest Ice Age. … This one is called the Pacific Coastal theory.
What are the theories of migration to the Americas?
Two theories currently explain the arrival of humans in the Americas: the Bering Strait land bridge theory and the coastal migration theory.
Which group of people arrived first in America?
For decades archaeologists thought the first Americans were the Clovis people, who were said to have reached the New World some 13,000 years ago from northern Asia. But fresh archaeological finds have established that humans reached the Americas thousands of years before that.
