The Ecology, Evolution, and Behavior option provides students with an education in ecological studies and biodiversity, and also emphasizes field experience. The degree requires courses in genetics, ecology and evolution, as well as at least one advanced course in cellular or molecular biology, physiology/behavior and biodiversity. Students have the option of tailoring their course and lab requirements in some of these areas to emphasize animal, plant, or ecological studies. Graduates may take positions with government agencies, enter consulting firms, or continue with graduate studies for an academic career at colleges, universities, museums, or other research organizations.
