Understanding Human History: An analysis including the effects of geography and differential evolutionMichael H. Hart (2007)Understanding Human History is a history of humanity, beginning about 100,000 years ago and going through the 20th century. It includes discussions of developments in every major area of the world. Unlike other books on world history, it explicitly discusses racial differences in intelligence, and explains how, why, and when they arose. The book also discusses the many consequences that those differences have had on human events, starting in prehistoric times and continuing to the present. The book includes an abundance of data and tables, together with sixteen maps, three tables, an extensive bibliography, and a thorough index.Michael H. Hart is both a trained scientist and a successful history writer. He did his undergraduate work at Cornell University, where he majored in mathematics, and later obtained a Ph.D. in astronomy from Princeton University. He also has master s degrees in two other fields (physics and computer science). His published work in scientific journals includes several detailed computer simulations of atmospheric evolution. His best known history book is The 100: A Ranking of the Most Influential Persons in History, which has been translated into over a dozen foreign languages and has sold several hundred thousand copies. That book has been widely praised for its scope, its lucidity, and its factual accuracy.Reviews: https://www.vdare.com/articles/a-real-diamond-michael-harts-understanding-human-historyhttp://www.toqonline.com/archives/v7n4/748RositHart.pdf
