Artifacts find revises understanding about first North Americans

SCIENTISTS excavating a creek bed in Texas found tools and other artifacts dating back 15,500 years, making it the oldest settlement site ever found in North America.

The objects unearthed at an archaeological dig in the Buttermilk Creek complex near Austin suggested that humans settled the continent some 2,000 years earlier than previously believed.

The discovery could lead to a radical revision of who the first American inhabitants were, and when they settled the continent, the researchers said.
