Background information: For many years scholars believed that the first humans to arrive in North America crossed over a land bridge from Siberia between 13 and 15 thousand years ago. This area, now the Bering Strait, was exposed during the last Ice Age. The theory further surmises that some of these peoples migrated south during a brief period when two ice sheets, the Laurentide and Cordilleran, drifted apart. Recent archaleogical and genetic evidence have pretty much upended the surety of the earlier theory. There are now multiple theories. Below are sources that you and your students may use to for more explicit information. **
