Based on the author's extensive fieldwork, this classic ethnography, now publishing in a legacy 6th edition, focuses on the Yanomamo. These truly remarkable South American people are one of the few primitive sovereign tribal societies left on earth. This new edition includes events and changes that have occurred since 1992, including a recent trip by the author to the Brazilian Yanomamo in 1995. Also included in this legacy edition will be an interview Q&A with the author revealing his own take on his life's work in the context of recent controversy. This interview will cap the legacy edition with rich perspectives from the author, his fieldwork, and the field of anthropology.
