Discuss the three elements that archaeologists generally associate with the development of ancient civilizations: large food surpluses, diversified farming economies, and irrigation agriculture. How do these elements fit into models for the origins of ancient states? What are some archaeological examples of these elements?

The Kennewick Man case study is an example of how different stakeholders in the past fail to collaborate, leading to a loss of knowledge and increased feelings of resentment toward one another. How could the study of Kennewick Man have benefited from the collaboration between archaeologists and various indigenous communities? Discuss with reference to the aims of indigenous/community archaeology and the Society of American Archaeology's Principles of Archaeological Ethics.
