The First Americans
In the 1970s, college students in archaeology such as myself learned that the first human beings to arrive in North America had come over a land bridge from Asia and Siberia approximately 13,000 to 13,500 years ago. These people, the first North Americans, were known collectively as Clovis people. Their journey was made possible, according to archaeologists far and wide, by a corridor that had opened up between giant ice sheets covering what is now Alaska and Alberta. Thus did the Clovis people move down through the North American continent, carrying their distinctive tools to various sites in the Plains States and the Southwest and then moving eastward. And all of this they did very quickly. Significant evidence of Clovis culture had been discovered in New Mexico. Clovis First, as it was called, was the one and only accepted explanation of initial human arrival and subsequent expansion throughout North and South America. Miller wondered what else lay beneath that patch of soil.
