This course examines the multifaceted interactions and relationships humans have with the biotic world from the ecological and evolutionary perspectives in order to understand these as an adaptive system with both a biological and cultural component. Emphasized in the course is the value of taking multi-cultural approaches to understanding human relationships to the natural world and how we can make use of traditional knowledge in an ethical manner. Students are expected to develop a critical awareness of the history and current status of the underlying theories and methodologies of ethnobiology and to apply their knowledge and understanding by undertaking an activity-based individual or group project.
