My Inuit friends have been perplexed by the white man's theory that aboriginal migrants crossed from Asia to North America only over a land bridge. No one would sit on shore, look at islands where the hunting might be good, and then wait for ten thousand years for the ocean to go away. White men have some crazy ideas.
White men are too crazy.
In recent years, archaeologists have unearthed abundant evidence that the Inuit are probably right. The most recent land bridge linking Asia with North America formed between 25,000 and 14,000 years ago when huge amounts of ocean water evaporated and then froze to form the continental glaciers of the last ice age. However, even during the glacial maximum, central Alaska was free of ice. Undoubtedly, people wandered back and forth between Siberia and Alaska during this time. But that is only part of the story.
