Study suggests humans were in North America 100,000 years earlier than believed
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.
