A. Guns, Germs, and Steel written by Jared Diamond holds an obvious purpose of the book: to explain why history is the way it is. It is a thought provoking idea to explain, but it certainly isn’t the first book to answer the question. At a glance, one may think this book is literally about guns and steel, and maybe the word “germ” holds a deeper meaning. After reading the book, readers will find that Guns, Germs, and Steel is, in fact, about guns, germs and steel.

Well, Diamond answers this himself in his epilogue, “I am thus optimistic that historical studies of human societies can be pursued as scientifically as studies of dinosaurs…” The way Diamond attacks history to find answers is quite exceptional.

In the chapter where he speaks of axis orientations affecting diffusion, Diamond uses a map of the globe and arrows to call attention to the directions of the spread in major continents. He additionally uses documents like he had when speaking of the Atahuallpa’s capture. Diamond uses these types evidence well. It does not confuse readers and instead helps readers visualize and thoroughly understand the matter the author speaks
