Some of the stone tools 15,000 years ago discovered in Texas, which are evidence of the oldest known culture of America 
Debra L. Friedkin site where archaeologists have found the oldest tools of America until now. :: MICHAEL R. WATERS Who were the first inhabitants of America? For decades, in view of the archaeological remains have been found, experts should be considered that the Clovis hunters some 13,000 years ago. Come to this continent from the northeast Asia to Alaska, crossing the strip of land in what is now the Bering Strait, and southward spread of the new territory. Devices made with particular characteristics that identify them. But now they've discovered in Texas (USA) thousands of pieces, including tools to cut and scratch, in a group of people before the Clovis people. These pieces are about 15,000 years and shows that someone had come before to America. The discovery is announced in the journal Science. Artifacts reservoir
Texan named Debra L Friedkin, are made of flint and are small, suggesting to researchers that would be prepared to take with lightweight tools from one place to another comfortably, a kind of campaign team. The site is near a stream that has water all year round and a place where there are plenty of flint, and it would be a good place chosen by a group of prehistoric peoples to manufacture the tools need it.
The vast majority of the 15,528 pieces of stone flakes are recovered and studied, which is to make hitting the stone tools in the points needed to tease out a cutting edge. But there are a dozen bifaces and some cutters, a total of fifty finished artifacts. Serve to work on bone, wood or ivory and skins for cutting or processing.
"In Debra L Friedkin found evidence of early human occupation 2,500 years before the Clovis people, making the site in the oldest archaeological site credible Texas and North America, and is important in the debate about time of colonization of America and the origins of Clovis, "said Michael R. Water (University of Texas A & M), team leader of the discoverer, who has worked in this field since 2006.
The new pieces, dated between 13,200 and 15,500 years have appeared in the reservoir level below the known remains of Clovis, and specialists, studying each other, claim that the latter developed the techniques of the first characteristics giving them their tools and weapons. This cultural evolution solve One of the problems of the thesis has been defending the American pioneers clovis, and who have not found those specific technological characteristics in Northeast Asia, making it difficult to associate human culture to travel through this territory. In the light of new findings, these tools would be an evolution Clovis those which were manufactured in America. Researchers remind
in Science that it had found some traces preclovis in several places, but they were too scarce to draw conclusions.
The first Americans, 2,000 years older than previously thought
The discovery in Texas of an archaeological site containing thousands of relics dating back 15,500 years ago more than 2,000 years to the date which were believed to have the first tenants arrived to America, questioning the current theory on the colonization of the continent.
This study traces back to the first Americans to the tribes of the Clovis culture, whose remains were found in various places since 1932. According to this controversial hypothesis, carriers of this culture is characterized by a particular technique of importance of the tips of flint bifaces have come from Asia around 13,500 years ago by the Bering Strait during the Ice Age.
They would then spread over the continent to reach South America. The new archaeological Texas' Debra L. Friedkin 'and located about 70 kilometers northwest of Austin, documented with a record number of traces of human existence in the Americas before the Clovis tribes.
"Replace therefore question the current theory of the early American settlements," said Michael Waters, director of the University of Texas and lead author of this work.
According to Walters, this new discovery is a huge leap towards a new understanding of the first inhabitants of America.
