The Chiquihuite Cave, a Real Novelty? Observations about the Still-ignored South American Prehistory

The recently reported discovery of cultural evidence at Chiquihuite Cave (Zacatecas, Mexico), produced by humans of at least 26,500 calendar years ago, is a major advance in research into early human occupations in the Americas. Thirteen of the 239 lithic artifacts recovered from the SC-C stratigraphic component, dated during and before the Last Glacial Maximum, are illustrated in Ardelean et al. (2020. "Evidence of Human Occupation in Mexico around the Last Glacial Maximum." Nature 584: 87-92). Although waiting for more detailed technological studies, these types of artifacts have been reported in other sites, primarily in South America. The field evidence from sites predating the Last Glacial Maximum must now be included in all interpretations of the initial settlement of the Americas.
