The Earliest Americans introduces some of the different native peoples who populated America many years before the arrival of European explorers. Students learn how some of the earliest Americans arrived in North America as early as thirty thousand years ago along the Pacific Coast, while others traveled from Asia across Beringia, the land bridge. Over time, native peoples migrated throughout the North American continent and into Central and South America. Students explore how these early peoples adapted to their environments and developed unique cultures. Chapters focus on the Inuit, the Ancestral Pueblo and Mound Builders, and specific Native American peoples of the American Southwest, Southeast, and Eastern Woodlands.
