OverviewTaking a macrosociological, global approach, Human Societies offers an introduction to sociology that is truly comparative, cross-cultural, and historical. It compares societies over time and across environments, emphasizing the dynamics of social change. Its clearly developed ecological-evolutionary perspective provides a powerful theoretical framework for understanding the array of social arrangements found in human societies over the past 100,000 years. Since industrial societies are introduced only after this theoretical base has been firmly established and older, simpler, and smaller societies have been examined in detail, students see their own society (and other contemporary societies) in a broader and more meaningful way. By showing how social arrangements are related to the environmental and technological contexts that societies are situated in, Human Societies encourages students to look for the reasons why social arrangements are the way they are, and why they change over time.
