Humans already inhabited central Mexico today more than 30,000 years ago, according to new research.

That is the conclusion that experts came to after finding utensils in a cave in the center of the North American country.

The antiquity of the objects, including 1,900 carved stone tools, date back 15,000 years before any vestige previously found, according to a publication in the Mexican newspaper. The Day.

The Chiquihuit cave, the site of the discovery, is located 2740 m above sea level, in the Astillero Mountains, in the north of Mexico City. That area would have been occupied by humans 33,000 years ago and would have remained there for 20,000 years, according to data from the magazine. Nature.

"Our investigations provide new evidence on the age of human presence in the Americas," Ciprian Ardelen, one of the leaders of the studies conducted at the site and an archaeologist at the Autonomous University of Zacatecas, told AFP.

According to the carbon 14 tests to which the utensils were subjected, the oldest date from between 33 and 31 thousand years ago.

Studies also indicate that humans at that time most likely used the site seasonally.

In short, this finding increases curiosity to continue investigating the arrival of humans in the territory that is today the American continent -the last to be populated-, something much debated by experts. (I)
