Bering land bridge theory disputed
Schoolchildren can recite the story of the first Americans.

About 12,000 years ago, prehistoric humans walked out of Siberia, trekked across the Bering land bridge and down an ice-free corridor into inner North America, where they hunted Ice Age elephants and peopled the new world.

But mounting evidence is slowly turning that story to fiction, said Michael Collins, an archaeologist with the Texas Archaeological Research Laboratory at the University of Texas at Austin.

For more than 20 years, Collins and other scientists have been digging up artifacts from Chile to Texas that convince them the first Americans didn't walk here at all, but came by boat, and arrived much earlier than previously thought.
