Ancient human footprints dating back 23,000 years ago were discovered in a new study conducted in White Sands National Park in New Mexico. The results of this study were published last September.
The fossil tracks, which were discovered at the bottom of a dried-up lake in the national park, apparently belong to a number of children and teens and are now considered the earliest human finds in North America.
These findings reject the previous theory that humans appeared on the Americas 13,000 years ago – a theory based on archeological finds in the form of spears that were probably used to kill mammoths.
