The program focuses on the history, development, and interaction of living organisms on this planet. Majors study species evolution, the effect of environmental pressures on evolution, patterns of biological diversity, and species interaction within a given ecosystem. Degree programs within the department offer different levels of concentration. The BS prepares students for graduate study in the field and offers course work in population, community and physiological ecology, behavior, population theory, biogeography, natural history, genetics, systematics, morphology, and evolution. The BA is for students interested in natural history and the biological sciences who do not wish to continue with graduate study.

The knowledge gained from a Bachelor of Arts degree in Ecology and Evolutionary Biology of species evolution, biological diversity, ecosystem dynamics, and the interaction of environmental pressures and evolution creates a strong career foundation. Coursework in mathematics, chemistry, biology, physics, ecology, genetics, and evolutionary biology prepares BA students for work as educators, natural historians, community liaisons, writers, or research assistants. Students may also pursue graduate studies in life sciences, geography, environmental science, and law, among other fields.
