On September 23, local time, researchers reported that fossil footprints found in New Mexico, the United States, indicated that early humans had arrived in North America about 23,000 years ago.
According to reports, in 2009, David Bustos, the resource project manager of White Sands National Park in New Mexico, discovered these footprints for the first time on a dry lake bed in the park.
Recently, scientists from the US Geological Survey analyzed the seeds left in the footprints to determine the approximate age of these footprints.
Scientists believe that these footprints were produced between 21130 and 22,800 years ago.
