Clovis Spearpoints were found all over the Americas in the early 1900s, mainly in the Southwestern USA. This initially led to the theory that the “Clovis people” were first into the Americas, were the ancestors of American Indians who migrated from Asia over the Bering Strait, and settled the unpopulated and empty Americas over 10,000 years ago.
The Clovis points actually appear to be slightly modified European “Solutrean” Spearpoint, and are radically different from designs favored by stone age Asians in Siberia and where the Indians migrated form before crossing the Bering Strait.
It appears that Solutreans (Stone Age Europeans) may have been first to the Americas well over 13,000 years ago, and were numerically overwhelmed by the Asiatic Indians who then adopted the technology as their own.
