Guns, Germs and Steel

Guns, Germs and Steel was published in 1997 which sealed his global reputation. His book has turned into a National Geographic Special about 2005. The first part of the book discusses how some of the civilizations have progressed and have dominated and how others have not. He goes back 13,000 years to find out. In order for him to find the differences between the cultures, Diamond emphasizes the effects of food production, technology, government and religion. Then he expresses his opinion the differences among different cultures. He then concludes that it is ultimately geography, not biology or race that produced the cultural gap that his friend has pointed out.
