Guns, Germs and Steel

In his book Gun, Germ and Steel (1997), which he wrote mainly in an academic style, Jared Diamond seeks the answer to the following question: "Why did humans evolve on different continents, in different ways, and at different speeds?

To answer this question, Diamond emphasizes the following topics in the book:

- How was the way human ancestors spread from Africa to continents beyond?

- What are the effects of environmental conditions on the transition from hunter-gatherer tribes to the empire over the past thirteen thousand years?

- How did the encounters of people on different continents occur, and how did they end up?

- How is the transition from hunting and gathering to food production related to regional differences?

- How has this production process spread to the continents of the world, and how has its effect on microbes?

- How did the evolution of microbes occur in populated societies?

- Why have the effects of microbe exchanges between nationalities different, and why inequalities have arisen?
