The indigenous Americans. European?
For years we were taught that the origins of native Americans came solely from the land bridge between Alaska and east Siberia, but in 2006 tool remains of an early race challenges this theory.
Artifacts found at Cactus Hill Virginia date back to 16,000 B.C, much earlier than the land bridge period of 13,000 years.
This group of people used tools developed in the south of France by a stone age people known as the Solutreans, whose culture vanished some 18000 years ago. Its suggested that these people were the first explorers to cross the Atlantic using skin boats, as the arctic ocean was unfrozen during the last ice age,
This group followed the coastline of northern Europe, Greenland and eastern Canada where food sources were abundant, eventually reaching the east coast of America.
This theory is also supported by a growing body of linguistic, and physical evidence, even suggesting the Solutreans influence of the Cloves groups of western America, long before the Asian groups crossed the land bridge of Alaska.
In 1996, a 9000 year-old skeleton was discovered along the Columbia River in, and the research determined that the " Kennewick Man" was well built and had European skull features, different from the Asian remains of western America. But the debate of his origin is still going on, some suggesting his remains are from the known tribes of later Americans.
There is evidence that shows a vast difference of physical features between the east coast and west coast tribes, thus the theory that two waves of migration took place between 18000 and 10000 years ago, one from east Asia and one from the early European ice age continent.
