Carbon-14 tests, developed in the 1940s, have
provided archeologists with a very precise way of dating their finds that
existed in the past. With this method they can measure the age of organic
artifacts with a fair degree of precision up to the age of 50 000 years. C-14
tests prove that oldest traces of man in North America are about 12 000 years
old.
After decades of guesswork and unfounded
theories of lost European tribes and lost continents, it is now held as
conclusive that mankind first arrived in North America from Asia during the
Pleistocene age via the Bering Strait land bridge, also known as Beringia. C-14
tests also prove this theory with dental evidence. Those who made the crossing -
either by land or by water - were neither explorers nor settlers nor
adventurers. They were simply hungry men and women following the game on which
their livelihood depended. They were the Paleo-Siberians, the real discoverers
of the New World. By all scientific evidence the first Americans entered a land
quite different from the America of today. The climate of those glacial times
was cooler and rainier. Lakes and swamps existed where no water exists today -
i.e. in the deserts.
Increasing archeological evidence has pushed
the estimated date for human arrival in North America further and further back,
to about 50 000 B.C. The migration from Asia continued from this time over many
millennia in many waves.
There were three major waves of migrants.
-
Geological and archeological evidence
points to an ice-free corridor for several thousand years between about 40
000 B.C. and 10 000 B.C. along the spine of the Rockies. Immigrants
could come during this time period to the New World. During the Late
Wisconsinan Glaciations, about 18 000 years ago, however, the ice was at
its maximum and covered most of Canada and much of northern United States.
There was no migration at this time.
-
A second corridor was formed further
east along the Alberta - Saskatchewan plains during another melt.
-
Finally, a third passageway developed
around 10 000 B.C. to 8000 B.C. along the Yukon, Peace and Liard rivers.
From these routes early immigrants could have
dispersed eastward along the river valleys of the Great Plains, westward through
the South Pass of the Rockies to the Great Basin, southwestward around the heel
of the Rockies to southern California, or southward into Middle America all the
way to Tierra del Fuego at the southernmost tip of the New World (South
America). The people moved about as climate changed and the food supply
increased or decreased. Changing climate was always, and still is, a fact of
life. As each pioneer group reached a new area, they came upon a wide variety of
animals, many of which they had never seen before. But never once did they
encounter another human being who had preceded them - a true native. The reason?
There was a blank page in the natural history of the New World.
Later migrations to the New World occurred
long after the final submersion of Beringia, about 3000 to 1000 B.C. Eskimos
were one of the latest migrants of the ancient Americas, they came around 3000
B.C. |
