[[File:Americas satellite map.jpg|thumb|280px|A true-color image of the [[Americas]]. Much of the information in the image comes from a single remote-sensing device—[[NASA]]'s Moderate Resolution Imaging [[Spectroradiometer]], or MODIS, flying over 700 km above the Earth on board the [[Terra satellite]] in 2001.]]
The '''history of the Americas''' begins with people migrating to these areas from Asia during the height of an [[ice age]]. These groups are generally believed to have been isolated from the people of the "[[Old World]]" until the coming of Europeans in the 10th century from Iceland led by [[Leif Erikson|Leif Erikson,]] and in 1492 with the [[voyages of Christopher Columbus]].
The ancestors of today's [[Indigenous peoples of the Americas|American Indigenous peoples]] were the [[Paleo-Indians]]; they were [[hunter-gatherer]]s who migrated into North America. The most popular theory asserts that migrants came to the [[Americas]] via [[Beringia]], the land mass now covered by the ocean waters of the [[Bering Strait]]. Small [[lithic stage]] peoples followed [[megafauna]] like bison, mammoth (now extinct), and caribou, thus gaining the modern nickname "big-game hunters." Groups of people may also have traveled into North America on shelf or sheet ice along the northern Pacific coast.
