Ecology and Evolutionary Biology

Department of Ecology and Evolutionary Biology

The Biology major at Yale is a joint offering of the Department of Ecology and Evolutionary Biology (EEB) and the Department of Molecular, Cellular, and Developmental Biology (MCDB). Required coursework includes classes in biology, chemistry, physics, and math, as well as lab work. The EEB department offers courses in conservation biology, human genetic variation and evolution, the history of life, animal behavior, and field ecology. Seniors typically complete a long essay based on original research. Learn more at

This course presents the principles of evolution, ecology, and behavior for students beginning their study of biology and of the environment. It discusses major ideas and results in a manner accessible to all Yale College undergraduates. Recent advances have energized these fields with results that have implications well beyond their boundaries: ideas, mechanisms, and processes that should form part of the toolkit of all biologists and educated citizens.
