Stone tools found in a Mexican cave suggest that people were living in North America as early as about 26,500 years ago, much earlier than most scientists accept, a study says. It is a new step in the difficult and contentious process of establishing when people arrived in North America from Asia. Ciprian Ardelean, of the Autonomous University of Zacatecas, and others said they found stone tools and debris from tool-making that they dated back as far as 26,500 years ago. Prof Dillehay said the proposed date for the artefacts may be valid if it stands up to further scrutiny. Those age estimates are now “commonly disputed or simply ignored by most archaeologists as being much too old to be real”, she wrote.
