Cultural Anthropology: Tribes, States, and the Global System, Seventh Edition, provides balanced coverage of three dramatically different cultural worlds by focusing on problems of social inequality, human well-being, social justice, and sustainability. Author John Bodley challenges students to consider "big questions" about the nature of cultural systems: How are cultures structured to satisfy basic human needs? What is it like to be human under different cultural conditions? Are DNA, language, and environment determinants of culture? Are materialist explanations more useful than ideological ones? What are the major turning points in human history? Scale and power remains the primary theoretical framework, but cultural evolutionary perspectives have been expanded.
