"Scientists spend a lot of time trying to learn about the earliest Americans, but much remains unknown. Who were they? When, how, and from where did they enter the land?

Their theories--and the discoveries that prove and disprove them--are highlighted in this informative volume. Readers will feel like anthropologists and archaeologists themselves as they study photographs and read about bones and artifacts and what they reveal about the ancient cultures that roamed America many thousands of years ago"--Provided by publisher.
