The Earliest Americans
   The American continents include North and South America. They are connected and span two hemispheres, from the frigid Arctic Circle in the north to the icy waters aroud Antarctic in the South. Although this land mass narrows greatly around modern-day Panama, it stretches unbroken for more than 10,000 miles. This large and rugged land is isolated from the rest of the world by vast oceans. Yet, at one time, thousand of years ago, the Americas were connected by a land bridge to Asia. Most experts believe that the first people came to the Americas from Asia over this land bridge. This land bridge is known as BERINGIA.
   The first Americans arrived sometimes towards the end of the last ICE AGE, which lasted from roughly 1.6 million to 10,000 B.C.
