The presence of humans in North America is older than we thought, as stone tools found in a cave in central Mexico, and other evidence from 42 archaeological sites in faraway places, revealed that humans arrived in North America more than 30,000 years ago.

Reuters quoted scientists that they found 1930 stone tools, among them small chips and fine blades, may have been used for cutting meat, and small things were probably used as tips in the spears, proving that people lived in Chichett cave in a mountainous region in the Mexican state of Zacatecas.

The history of the tools stretches from 31,000 years to 12500 years, said archaeologist Ciprian Ardelene of the Autonoma Department of Desacatecas in Mexico.

And in a study A second time I referred to the journal Nature, evidence from 42 sites across North America, and the location of the land bridge that connected Siberia to Alaska during the last Ice Age, indicated a human presence dating back at least to a period called the Far Ice Age, when ice covered much of the continent, about 26,000 A year to 19 thousand years and immediately after that.


Showed studying Humans have also been involved in the extinction of many large Ice Age mammals such as mammoths and camels.

The human race first appeared about 300,000 years ago in Africa, before later spreading around the world.

The new findings contradict the traditional view that the first humans arrived in the Americas, an important event in human history, about 13,000 years ago, they crossed the land bridge and were associated with Clovis culture known as distinct stone tools.

The results indicate that a small number of people entered the continent earlier than previously understood, perhaps some of them by boat along a coastal road on the Pacific Ocean instead of crossing the land bridge, and some died without leaving a descendent.

Archaeologist Lorena Basera-Valdivia of the University of Oxford in England and the University of New South Wales in Australia said that after that the population of the continent expanded significantly from about 14,700 years ago.
