Revised Timeline: Ancient Footprints Challenge North America's Human Arrival

Ancient footprints discovered in White Sands National Park in New Mexico have reignited the debate about when the first humans arrived in the Americas. A study published in the journal Science confirms that the footprints are more than 21,000 years old, challenging the dominant belief that humans migrated to the Americas around 13,000 years ago. The study used evidence from pollen grains and quartz crystals to support the initial finding. While some experts remain skeptical, the discovery has prompted a reevaluation of long-standing assumptions about human migration into the Americas and has been welcomed by Indigenous communities as confirmation of their ancestral presence.
