For a very long time it was believed that the oldest evidence of humans in North America came from the Clovis Culture who resided on the continent approximately 13,000 years ago. And for quite a while the idea of humans occupying North America before 13,000 years ago was looked at as preposterous. But a new paper in Frontiers in Ecology and Evolution from Scientists at the University of Texas in Austin Texas describe the discovery of Mammoth bones with cut marks found in New Mexico’s Rio Puerco Canyon, and they consider this discovery as the most convincing evidence for the arrival of Humans in North America.
