This book came up so many times in school, always as some way to say Eurasians never had any inherent advantages. It's not that I think they do, it's just that I'm wary of people trying to reach a conclusion only because it's politically correct.

unless you plan to read a dozen academic books about a variety of topics, i dont really think there is a better option for a popular audience that will answer the question

"why were Eurasians able to so easily take over the Americas" than this book.
