The Clovis theory of humans only being in north america for the past 15000 years appears to be blowing up:
Study suggests humans were in North America 100,000 years earlier than believed
Researchers base opinion on tools found next to mastodon site in San Diego

A team of scientists believe they have found evidence of human activity in North America that dates back 130,000 years — more than 100,000 years earlier than believed.
The evidence comes from an archeological site in San Diego County, Calif. In 1992, a site was uncovered containing mastodon bones, along with stone anvils and hammerstones. Dating the tools proved to be challenging. However, using recent technology, including uranium dating, the team believes they have firm evidence that humans were using tools to break apart the bones and make other tools.
"When you look at the evidence — the material, the nature of the wear pattern on the bones, the actual mapping of the site — the evidence is absolutely incontrovertible," Richard Fullagar, co-author of the paper that appeared in Nature said during a teleconference.
