Archaeologists have uncovered 1,900 stone artifacts in Chiquihuite Cave, a high-altitude site in the Astillero Mountains in northern Mexico. DNA analysis of the plant and animal remains from the sediment packed around the tools dates the human occupation of the site to 25,000-30,000 years ago. These findings challenge the commonly held theory that the Clovis people were the first human inhabitants of the Americas 15,000 years ago. Team members entering...
