In this brilliant and profound study the distinguished American anthropologist Marvin Harris shows how the endless varieties of cultural behavior -- often so puzzling at first glance -- can be explained as adaptations to particular ecological conditions. His aim is to account for the evolution of cultural forms as Darwin accounted for the evolution of biological forms: to show how cultures adopt their characteristic forms in response to changing ecological modes.
