Footprints in the sand often only last as long as the next big wave or high tide. But footprints found in New Mexico’s White Sands National Park have lasted a lot longer than that.

In fact, scientists believe they’ve been there for more than 20,000 years. And the find could change the way we understand how and when humans first got to the Americas.

Vance Holliday is a professor of anthropology and geosciences at the University of Arizona. He's also one of the authors of the research on this.

The Show spoke with him to learn about the prints and how they were found.
