This course surveys the main theoretical ideas in ethology, the scientific study of animal behavior. We explore the physiological, developmental, functional and evolutionary bases of behavior as well as related issues in the study of cognition. The main reading and discussion material for the course is drawn from journal articles in the professional scientific literature; students are also expected to read John Alcock's standard textbook, Animal Behavior. Two summary/critique papers on the journal articles will be required, along with a report on a public lecture relevant to the themes of the course, and a full-length paper on a species and research topic of the student's choosing. The final project will also be presented to the whole class either orally or in a poster session.
