The Dhaka Times Desk Researchers found fossilized footprints of early humans at the bottom of a lake in New Mexico. It has been researched, these were signs of human presence in North America about 23 thousand years ago!
The footprints were found at the bottom of a dry lake in White Sands National Park. The first impressions were spotted by a park manager in 2009. Scientists from the US Geological Survey recently verified the age of these footprint fossils. It can be seen that the age of this fossil is estimated from 21 thousand 130 years to 22 thousand 800 years.
Most scientists believe that a large landmass connected Asia to Alaska. It was through him that the ancient migration began. Later this land was lost in the ocean.
On the other hand, based on various evidences including stone tools, fossil bones and genetic analysis, researchers said that humans arrived in North America about 13,000 to 26,000 years ago.
The latest research, however, provides a much more solid foundation for when humans were in North America, although they could have arrived earlier. They wrote that fossil footprints are a more undeniable and direct form of evidence than "cultural artifacts, altered bones, or other conventional fossils."
The latest research provides more precise evidence of when humans first appeared in North America. The researchers say this is a testament to the superiority of time and location.
Based on the size of the footprints, researchers believe that these are the footprints of children and teenagers. They lived in the last ice age. This research was published in the famous 'Science' journal on September 23.
