THE FIRST SETTLERS
OF AMERICA
THE TIME OF ARRIVAL OF THE FIRST HUMAN BEINGS TO AMERICA
For DNA data - the genetic human code - we know that the beginning of settlement of America happened at least 20,000 years ago.
THE ROUTE THAT FOLLOWED THE FIRST SETTLERS
The bridge or tunnel would provide a connection linking North America and South America and Asia.
GLACIATION PROCESS
GLACIATION ALLOWS TO CREATE A DRY LAND ROUTE (FROZEN STEPPE)
CLOVIS
Tools: leaf-shaped, fluted spear points called Clovis points.
The lower part in the form of a fish tail
Archeologists believed were the first people to cross a land bridge between Siberia and Alaska at the end of the last Ice Age.
The culture is named for artifacts found near Clovis, New Mexico.
THE SETTLEMENT OF AMERICA
It might be surprising that these hunters and collectors, who had type tools Clovis, could reach Patagonia - located at 13,000 km south of the US-Mexico border UU Y Canada- in less than 100 years. According to a biologist to travel 13km annually is a medium average for a hunter who could travel that distance in one day looking for food.
THE LIFE OF THE FIRST SETTLERS
Both in the North and in the South of America, the primitive settlers found abundant and easy hunting.
They met with thousands of thousands of animals in the great plains from the south of the current Canada and the center of the USA.
They found: mastodonts lions, deer, saber-tooth tigers
In South America they found mostly herbivores. They found: Sloths Camels: Lama Horses Armadillos
MEGAFAUNA
All representatives of the megafauna ( giant animals) are extinct.
It extermination concluded 10,000 years ago and it was massive and fast
CAUSES
Hunting : Human beings Weather: Glaciation
