(Desert Research Institute) Archaeological evidence has increasingly called into question the idea of 'Clovis First.' Now, a study published by a team including DRI's Kathleen Rodrigues, Ph.D. student, and Amanda Keen-Zebert, Ph.D., associate research professor, has dated a significant assemblage of stone artifacts to 16-20,000 years of age, pushing back the timeline of the first human inhabitants of North America before Clovis by at least 2,500 years.
