Most of paleontologists agree that the only route was the current Bering Strait,
but there are some few scientists, such as Donald Lathrap, 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,
specifically towards the coastal region of the Amazon Jungle.
The discovery of the Clovis culture in
New Mexico pushed the settlement of
North America back to what
archeologists believed were the first
people to cross a land bridge between
Siberia and Alaska at the end of the
last Ice Age.
As a result of the glaciations, the height of
the Bering Sea changed several times, sometimes leaving a dry land route
between Asia and America, and at other times flooding it
It might be surprising that
these hunters and collectors,
who had Clovis type tools,
could reach Patagonia -
located at 13,000 km south of
the US-Mexico border USA
and Canada- in less than 100
years. However, as the
biologist Jared Diamond has
calculated, this is equivalent
to an average advance of
only 13 km per year, a very
easy expansion for a huntergatherer, who could probably
cover this distance in a single
day in search of food
Both in the North and in the South of
America, the primitive settlers found
abundant and easy hunting. Once
the first settlers crossed the ice zone,
in several generations, and 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
Canada and the center of EE. UU.
All the representatives of the megafauna, that is to say, giant animals, today they
are extinct
There are those who say that large mammals of America became extinct due to
climate change at the end of the last glacial period, but some people wonder why
they survived 22 glacial periods before and in the 23 glacial period all at once died.
