Guns Germs And Steel Summary

Decent Essays

Cassidy Elibol Prologue In the prologue of Jared Diamond’s book, Guns, Germs, and Steel, Diamond introduces readers to a question posed to him by Yali, a New Guinean politician. Yali inquired about the reason for different developmental rates of civilizations, and Diamond, who couldn’t explain at the time, began to search for the answer. Diamond links certain “power factors,” such as advanced weaponry, certain diseases, and metal tools, to the rate of advancement in civilizations. However, the causes for the creation and use of the “power factors” in some civilizations, but not others, remains an unsolved mystery. In the prologue, fittingly titled “Yali’s Question,” Diamond expresses his belief that throughout history, civilizations develop …show more content…

He compares three places that all developed food production and in which place it was more effective than the other two: Western Eurasia, specifically the Mediterranean and Fertile Crescent zones, New Guinea, and the Eastern U.S. Diamond first describes advantages of the Fertile Crescent that made it so suitable for farming. First, the Mediterranean climate with long dry seasons caused plants to adapt and consequently they were able to be stored for a long time. Second, the flora of the Mediterranean was previously abundant and productive, so they didn’t need to change much to be able to be cultivated. Lastly, many of the plants were self-pollinating, therefore they could keep the positive traits they were selected for by humans. These adaptations allowed food production to rise quickly and allowed for people to begin the process of civilization. Thus, the Fertile Crescent became one of the first cites of …show more content…

First, Diamond talks about a few ways that disease can spread. One way is by waiting to be transferred between victims. For example, microbes that travel on food are contracted this way. Another passive way of transmission is by surviving in insect saliva and then passing to a host when the insect bites. Disease can also spread in aggressive ways, for example, some microbes change their host’s body so transmission is accelerated. Smallpox uses this technique by forming skin lesions. Microbes can also travel amongst people by forcing infected individuals to cough or sneeze, which in effect shoots the microbes toward other host bodies. Next, the author lists the efforts of the human body to expel the disease. For instance, a fever is one way a body can rid itself of microbes, specifically heat-sensitive ones. Other times, blood cells will hunt down and exterminate disease-causing organisms, and build up resistance to that organism in case it ever reenters the body. The final and slowest defense Diamond lists is natural selection. Humans with genes for resistance live longer and pass on the traits, creating more individuals who can survive against a certain
