Their physical resemblance to the people of East Asia has long been recognized. More specifically, based on similarities in language, teeth, and DNA, there is nearly unanimous agreement that the ancestors of the Native Americans originated in Asia. It is also generally agreed that they migrated to the New World along or through the Bering Strait Land Bridge. The land bridge connected Siberia with Alaska and would have included the Aleutian Islands. The huge land mass was created when sea levels dropped 100 meters because so much of the earth’s water was locked up in the glaciers. In 1999, Dennis Stanford and Bruce Bradley proposed an Atlantic crossing and a European origin for Native Americans. Their argument is based on technological similarities between European Upper Paleolithic artifacts and 13,000 year old Native American artifacts. However, these similarities are probably the result of parallel technological developments rather than cultural connections. Although many archaeologists would concede that transatlantic sea travel may have been possible 18,000 years ago, there is little other supporting data for a European origin, and the majority of archaeologists continue to support a
