Ancient DNA reveals a new group of people who lived near land bridge between the Americas

NEW YORK (AP) — Scientists have identified a new pod of ancient hunter-gatherers who lived near the land bridge between North America and South America about 6,000 years ago.

Researchers are still charting how human populations spread across the Americas thousands of years ago, arriving first in North America before veering south. Groups that split off developed their own collection of genes that scientists can use to piece together the human family tree.

Discovered through ancient DNA, the group lived in the high plateaus of present-day Bogotá, Colombia — close to where the Americas meet. Scientists aren't sure exactly where they fall in the family tree because they're not closely related to ancient Native Americans in North America and also not linked to ancient or present-day South Americans.

The new study was published Wednesday in the journal Science Advances.

“Up to this point, we didn’t believe there was any other lineage that would appear in South America," said archaeologist Andre Luiz Campelo dos Santos with Florida Atlantic University who was not involved with the new research. “This is unexpected.”
