This book provides terrific information on the subject including facts and photos, but the editing and presentation of said is sort of annoying. References in chapters to photos do not match "photo below" when the photo might be 20 pages beyond at the end of the chapter with all the other photos. Grammar check was not preformed as various sentences and sometimes whole paragraphs are repeated throughout the book, it's just aggravating!The book does convey the facts about the subject and I would recommend it to anyone who is interested in the true history of the human race...
