New findings from fossilized footprints challenge the belief that humans arrived in the Americas 14,000 years ago. The footprints were found in White Sands National Park, New Mexico, and are estimated to be between 21,000 and 23,000 years old. This discovery raises questions about how humans arrived in the Americas and their role in the extinction of megafauna. However, critics argue that the dating technique used in the study is flawed.https://ift.tt/iYJxdGI
