Bachelor of Arts - Biology; Natural History Concentration

College of Humanities & Sciences

Degree Specific Credits: 74

Required Cumulative GPA: 2.0

Catalog Year: 2018-2019

Note: The Natural History concentration is designed for students who seek an interdisciplinary science program. This concentration is not research-oriented and is not considered a preparatory program for traditional research-based graduate programs. It is, however, designed for students seeking careers in environmental education, science writing or illustration, natural history or wildlife film-making, or natural history centers or museums. There is enough latitude in the requirements to allow for a minor or even a double major in a related field of interest (e.g. journalism, art, media arts, etc.).
