Footprints found at ancient lake in New Mexico challenge old belief of first humans in Americas

New research finds that humans might have first entered the New World not over the Bering land bridge between Russia and Alaska, but thousands of years earlier.
According to research published Thursday in the journal Science, footprints discovered at the edge of an ancient lake bed in White Sands National Park date back to between 21,000 and 23,000 years ago.
The finding challenges what many archaeologists believed to be true, that humans did not reach the Americas until about 15,000 years ago when they crossed the Bering land bridge between Russia and Alaska — perhaps about 15,000 years ago.
