The book is about the field work that Dr. Chagnon worked on when he went to the Yanomamo. He went through many difficult and difficult times. From the start, things weren't great; he almost decided to go home. The first contact with the Yanomamo was very difficult. They were very intimidating and closed-minded. They lied to Dr. Chagnon in order to protect their relatives' information. The Yanomamo made fun of him by creating false names. After a while, Dr. Chagnon managed to gain their trust. Through balanced reciprocity, he was able to gain their trust. At that point, he could now obtain information in exchange for the goods he owned, for example like machetes, food or tools. Dr. Chagnon faced many challenges; people stole his goods, his food and his gasoline. All this delayed the investigation. Dr. Chagnon was very persistent and managed to obtain the information. This shows how passionate Dr. Chagnon is, he even says that some people tried to assassinate him during his stay. “There have probably been more major change events in the last 10 years than in the previous 100 years of Yanomamo history (Chagnon 233). » Throughout the book we can see how culture changes. They began to believe that positive reciprocity was the key to their success. Dr. Chagnon returned to the villages after a while and was amazed at the changes in the Yanomamo community. I will talk about the cultural change that is happening in the Yanomamo community. There are a lot of positive things that come with these changes. Most changes have pros and cons. Yanomamo is dramatically affected by foreigners. The Brazilian gold rush and Salesian missionaries arrived at the Yanomamo site...... middle of paper ......increasing awareness of the outside world. The children of Bisaasi-teri, including those from the village of Kaobawa, regularly attend the mission school and follow a school year like those found everywhere in Venezuela. They even have the equivalent of a “school bus” system, a very large canoe which goes every morning to each of the 12 “villages” to pick up the schoolchildren and brings them back the same way in the afternoon (Chagnon 258). » Introducing a school system in a hunter-gatherer society must have been extremely difficult. By introducing this concept, the Yanomamo could experience a better organized society. It's amazing, before these changes, children only played all day. It's a great way to get the message across to the community that there are better ways to spend your time. Works Cited Chagnon, Napoléon A. Yanomamo. California: Wadsworth, 2012. Print.
