Artifacts From 15,500 Years found in Texas Question the Theory on The Colonization of America
The discovery in Texas of an archaeological site containing Thousands of remains of 15,500 years ago is back in at least 2000 years the estimated arrival of first settlers to America, besides, putting in doubt current theory on the colonization of the continent.
A current theory believes that the first tribes would be part of American culture known as Clovis, with traits found in several points from 1932.
According to this controversial hypothesis, carriers of this culture, characterized by a very particular notch technique would have been Asia about 13,500 years through the Strait of Bering, during the Ice Age. They would then spread throughout the continent, to get to America South
The new Texan site, called “Debra L. Friedkin” and situated about 60 km northwest of Austin, documents strong evidence of previous human occupation of the Americas pre-Clovis culture.
The finding calls into question the current theory of the first American people, said Michael Waters, director of Center for the Study of the First Americans University of Texas and lead author, published in the American journal Science, which will be in newsstands this Friday (25).
“This discovery forces us to rethink the origins of colonization of the Americas”, insisted the researcher. “No undoubtedly, these tools and weapons were manufactured by humans and have about 15,500 years age, making them the oldest remains found to date in North America”, he added.
“It is important to advance the debate on date of arrival of the first settlers of the Americas, but also to help us understand the origins of Clovis culture”, he said.
For example, there is no trace of “technology” of Clovis in Northeast Asia, where these settlers had come.

Still, the flint arrowheads discovered in Alaska and in a thousand years that preceded the arrival of the tribe Clovis were constructed differently.
Anyway, this adds archaeologist, dating from the six sites same period of the “Clovis” discovered in America South do not contain any trait that can be assimilated this “culture”.
“These facts lead to the conclusion that Clovis does not could be the first Americans and other men were already in America before”, completed the scientist.
Among the early warning signs, the scientist mentions primarily on two sites in Wisconsin (north) dating 14,200 to 14,800 years, the Paisley Caves in Oregon (14,100 years) and Monte Verde in southern South America (14,500 years).
“Overall, it’s time to abandon once and for all the theory of colonization of Clovis and develop a new model to explain the peopling of the Americas. In this sense, the site Debra L. Friedkin took a big step toward this new understanding of the early inhabitants the new world”, insisted Michael Water.
The dating is done through a technique luminescence, calculating that when the sediments cover the remains were exposed to light last.
