New World’s first humans may have come via Arctic

Nunatsiaq News – Two U.S. scientists have published a radical new theory about when, where and how humans migrated to the New World, arguing that the peopling of the Americas may have begun via Canada’s High Arctic islands and the Northwest Passage — much farther north and at least 10,000 years earlier than generally believed. The hypothesis — described as “speculative” but “plausible” by the researchers themselves — appears in the latest issue of the journal Current Biology … For decades, the Canadian Museum of Civilization has stood largely alone in defending its view that the Yukon’s Bluefish Caves hold evidence of a human presence in the Americas — tool flakes and butchered mammoth bones — going back about 20,000 years.
