North America Settled Earlier Than Expected
by The history of the settlement of North America must be well written. So far were the stone-age people of Clovis as the first arrivals. But now researchers at Texas instruments of a much older culture have discovered.

Washington – The discovery of stone tools 15,500 years old in Texas ensures that the settlement of North America can be dated from scratch. The new findings suggest that the first immigrants ventured some 2,500 years earlier than first thought on the empty continent. So far, the Clovis from Asia as the first settlers of America had been considered.
13 200 years ago they came across the Bering Strait, which was still a peninsula, in present-day Alaska and had spread to the north of South America. But as a research team led by Michael Waters of the University of Texas now in the scientific journal “Science”, writes the 2,500 years older than the Clovis stone works refer to the number two ranking early “American.”
Whether the members of the Clovis-clans – named after a locality near the same village in the state of New Mexico – in fact, the first settlers in America were about scientists arguing for some time. The new find is the doubters at the “Clovis First” theory now seems right.
Waters and colleagues met at a known as Debra L. Friedkin reference in the Buttermilk Creek Site Complex (buttermilk Bach complex) of Texas to have a surprisingly sophisticated tools of the Clovis predecessor. Similarities with the stones of the Clovis made it appear that the later Clovis culture built up their craftsmanship to the now found, according to “Science”. Even the pre-Clovis tools had been cut and were double-hand use, the researchers write. But who were the predecessors, is still in the dark.
The 15 528 pre-Clovis artifacts have been excavated at Buttermilk creek under a layer of Clovis remains. For them it is according to estimates by Waters and colleagues for “mobile tool kit” that could be easily packed and taken to another place.
Findings in other U.S. states, Wisconsin, Pennsylvania and Florida, had already aroused the suspicion that the Clovis were not the first “Americans”. Doubts about the “Clovis First” theory, six archaeological sites were give rise in South America, its tools from the time of Clovis originate, but do not exhibit the unique characteristics of Clovis. Thanks to the finds in Texas and a new luminescence technology that sets her age at 15,500 years, the U.S., according to Waters Einwandergeschichte can now finally correct.
