A new find on a 13000 year old girl and her American roots.
A teenage girl may have gotten lost in a cave looking for water, nearly 13,000 years ago. Naia, as she's known today, likely fell to her death in a deep, dark pit. Now, her remains are shining a light on the genetic heritage of what we believe are the first people in the Americas. Researchers have discovered Naia's bones in a pit in an underwater cave system in Mexico's Yucatan Peninsula. Her skeleton, described in the journal Science this week, is one of the oldest of any humans found in the Americas. She comes from a group of ancient people anthropologists call Paleoamericans.
