Peopling of the Americas, Currents, Canoes, and DNA [PDF ebook] 

This book provides an answer to the question ‘Who are the Native Americans?’ Their origins are significant in world history because they suggest early globalization. ‘Peopling of the Americas, Currents, Canoes, and DNA’ explains that cultural diffusion from the Old World to the New World is a reality and a concept no longer to be marginalized. Peoples of many ethnic backgrounds entered the Americas from many parts of the globe very early in our history. Seen from this perspective, America is not really a new country, but has a long and rich pre-history revealed to us through archaeology and skull morphology research and most recently by DNA and genetic studies. Science, especially genetics, has meshed with cultural history to create this book explaining multiple origins of Native Americans.
