Oldest Known Human Footprints in North America
In 2021, researchers uncovered ancient human footprints in White Sands National Park, New Mexico, dating back approximately 23,000 years. These footprints, preserved in lake sediment, provide direct evidence of human presence in North America during the Last Glacial Maximum. This finding challenges previous timelines of human migration into the continent, suggesting that humans arrived earlier than previously thought and adapted to diverse environments during their migration.
