In a lofty cavern, archaeologists discover spear points, other implements that indicate people were living in North America earlier than previously believed
Archaeologists in Mexico found stone tools and other signs that people were living in North America 30,000 years ago, much earlier than widely believed, according to new research reshaping the debate over the origins of people in the Americas.
In a study reported Wednesday, scientists led by archaeologist Ciprian Ardelean at Mexico’s University of Zacatecas said that they had unearthed hundreds of unusual green limestone spear points, blades and other implements from a lofty cavern in the central Mexican highlands. For wandering hunter-gatherers, the cave served as a makeshift tool shed possibly beginning as early as about 33,000 years ago, the scientists said.
These new finds at Chiquihuite Cave, located almost 9,000 feet above sea level and about 400 miles northwest of Mexico City, are the latest in a series of discoveries across North and South America that have archaeologists pushing humankind’s entrance into the Americas deeper into antiquity. The discoveries in Mexico were published in the journal Nature.
“It is a fundamental change in our way of thinking,” said anthropologist Ruth Gruhn, an emeritus professor at the University of Alberta who helped pioneer studies of early migrations into North and South America. She wasn’t involved in the find. “Dates of around 30,000 years ago indicate that people have been on both continents twice as long as generally believed.”
