The search for early Americans is taking researchers to the coast of
British Columbia, where a now-submerged landscape may hold clues to
the first settlers' coastal migration.

World: Rewriting Prehistory
Early Americans may have first migrated to
the continent on boats along the Queen Charlotte Islands region off the coast
of British Columbia, Canada, until a warming period about 10,000 years ago. That
warming would have contributed to the severing of the islands from the Canadian
mainland. Research suggests that marine habitats for the area about 10,000 years
ago were very similar to those of today, shown here. This photo of southern Graham
Island in Queen Charlotte Islands is by R.I. Thompson. Find out more about the
progression of thinking on human migrations in "The
