Gus germs and steel

Gas bacteria and steel galls asked diamonds "why Caucasian people develop a large number of merchandise and bring it to New Guinea, but most of them do not have it." . In other words, the difference between a winner and a loser is in a geographical place. Chapter 1 "Great Leap Forward" was developed in the history of human beings about 50,000 years ago. Huge snoring in New Zealand and huge lemur in Madagascar were wiped out by humans.

Guns, bacteria, and steel aim to answer the biggest problems of human history in post ice era. Since the population of other continents has obvious benefits, aliens who visited the earth 14,000 years ago may be allowed to fail to predict this result. Since Africa is by far the oldest continent in human occupation, Africans are taking a big start. North America is a fertile continent and, as a result, supports the richest and most productive country of today. To date, Australia has provided the earliest evidence of the ability of humans to cross a wide water gap, and some of the earliest and broadest evidence of actions in modern human beings. But why do Eurasians want to expand?

Jared Diamond's guns, bacteria, and steel are clearly focused and seek answers to the question 'Why human development develops at different speeds on different continents' and is convincingly offered. In other words, why did Columbus "conquer the Inca" and "conquer" Europe by "America" ​​and "Pizarro" than the Inca? Why is Europe colonizing Africa, not the opposite? He can not be satisfied just by considering the immediate cause of "gun, bacteria, steel", but postponed 13000 years to judge why it is not Europe, not guns, Inca's bacteria, steel. did.
