Answer:
part from the brief visit of the Scandinavians in the early eleventh century, the Western Hemisphere remained unknown to Europe until Columbus's voyage in 1492. However, the native peoples of North and South America arrived from Asia long before, in a series of migrations that began perhaps as early as forty thousand years ago across the land bridge that connected Siberia and AlaskA.
The first Americans found a hunter's paradise. Mammoths and mastodons, ancestors of the elephant, and elk, moose, and caribou abounded on the North American continent. Millions of bison lived on the Great Plains, as did antelope, deer, and other game animals, providing the earliest inhabitants of the Americas, the Paleo‐Indians, with a land rich in food sources. Because food was abundant, the population grew, and human settlement spread throughout the Western Hemisphere rather quickly.
The Paleo‐Indians were hunter‐gatherers who lived in small groups of not more than fifty people. They were constantly on the move, following the herds of big game, apparently recognizing the rights of other bands to hunting grounds. These early native people developed a fluted stone point for spears that made their hunting more efficient. Evidence of such fluted points has surfaced throughout the Americas.
