FIRST SETTLERS OF AMERICA
THE TIME OF ARRIVAL OF THE FIRST HUMAN BEINGS TO AMERICA
settlement of America happened at least 20,000 years ago.
THE ROUTE THAT FOLLOWED THE FIRST SETTLERS
Most of paleontologists agree that the only route was the current Bering Strait
There are some few scientists who argues that there was some migration of humans from Africa, who would have sailed around 10,000 years ago through the Atlantic towards America South.
A Bering Strait crossing is a bridge would providea connection linking North America and South America and Asia.
How did they cross if there was water?
As a result of the glaciations the height of
the Bering Sea changed several times, between Asia and America,
CLOVIS TECHNOLOGY
The Clovis culture in New Mexico pushed the settlement of North America
The archaeologists differentiate
them, especially for the shape of the carving of some arrowheads of great size, with a peduncle, that is to say, they had with a lower part in the form of a fish tail, well carved by both sides.
THE SETTLEMENT OF AMERICA
Hunters and collectors to get from one place to another to an average advance of only 13 km per year.
They went south in search of a better weather, far of the northern ice this is one of the hypothesis
The other hypothesis is that they were in search of prey to hunt when finishing with hunting in one place, they would have moved to find them further south.
THE LIFE OF THE FIRST SETTLERS
Both in the North and in the South of America, the primitive settlers found abundant and easy hunting.
Sometimes the first settlers crossed the ice zone, probably following the coast from the Pacific they literally met with thousands of thousands of animals in the great plains from the south of the current.
SOUTH AMERICAN MEGAFAUNA
In South America there were different types of giant terrestrial sloths, called mylodonts and megatherium mastodons and horses, all these animals were giants
MEGAFAUNA EXTINCTION
They became extinct 10,000 years ago. They extinct probably because of the hunting by humans.
There are those who say that large mammals of America became extinct due to
climate change
Some people wonder why they survived 22 glacial periods before and in the 23 glacial period all at once died.
