Revised Timeline: Oldest Human Footprints in North America Rewrite History

New research confirms that fossil human footprints found at White Sands National Park in New Mexico are between 21,000 and 23,000 years old, extending the timeline for the earliest human arrivals to North America. The findings challenge the previously accepted belief that humans arrived in the Americas around 13,000 years ago. The confirmation was achieved through two independent research approaches, including radiocarbon dating and optically stimulated luminescence dating. The footprints provide evidence of human presence during the Last Glacial Maximum and suggest that humans lived alongside North American megafauna species for thousands of years before their extinction.
