Question

The migration from Siberia to North America might not have been made over an ice/land bridge. What is the name of the theory that suggests the settlers used a sea route that hugged the coasts and islands along the way?

Answer 1

The answer is - coastal migration hypothesis.

The coastal migration hypothesis suggests that people managed to get to the Americas not through the Bering Ice Bridge, but along side the coastline and the Kurile island chain. Also this hypothesis suggests that people managed to enter the Americas earlier than thought, and this is also supported by few archaeological findings, including ones in Chile, Florida, and close to the coast of California.
