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 Science degree in Ecology and Evolutionary Biology of species evolution, biological diversity, ecosystem dynamics, and the interaction of environmental pressures and evolution creates a strong academic foundation for careers or graduate study. Rigorous coursework in mathematics, chemistry, biology, physics, ecology, genetics, and evolutionary biology, as well as a capstone project, prepares BS students for graduate programs in the life sciences, geography, environmental science, and law, among other fields. Graduates with a BS may also find work as field or laboratory scientists, consultants, educators, science writers, or communications specialists.
