4.1 Civilizations of Middle America

The Americas refers to two continents, North America and South America. Within these two regions is a cultural region that historians call Middle America or Mesoamerica, which is made up of Mexico and Central America. Some of the earliest civilizations in the Americas developed in Mesoamerica.

Civilizations Develop in the Americas

Scholars disagree about exactly when and how the first people reached the Americas. A common theory held that between 12,000 and 10,000 years ago, Paleolithic people reached North America from Asia. This migration took place during the last Ice Age, which lasted from about 100,000 years ago to about 10,000 years ago. At the time, so much water froze into thick ice sheets that the sea levels dropped, exposing a land bridge between Siberia and Alaska in the area that is now the Bering Strait.

Early evidence supported the theory that bands of hunters and food gatherers followed herds of bison and mammoths across the land bridge between Siberia and Alaska. They slowly moved south through North America, Central America, and South America. Recent evidence suggests that people may have reached the Americas much earlier. They may have paddled small boats and fished along the coasts. As archaeologists have discovered new evidence, they have modified their theories. Researchers now base the dates of migration into the Americas mostly on evidence found at prehistoric sites.
