Biology, B.S.

Return to {$returnto_text} Return to: Majors/Minors/Specializations

Biology is a diverse discipline, encompassing the health sciences (medicine, dentistry, and veterinary science), biomedical research, agriculture, ecology, teaching, and more.  A major in biology from Saint Leo University is designed as preparation for a career in the exciting and rapidly changing field of the life sciences, whatever the sub discipline.  In the laboratory, classroom, and field, biology majors will build a firm foundation in life and physical sciences by exploring the facts, theory, and methodologies employed by scientists today.

Three curricular concentrations are available: students can follow the general curriculum (General Biology) and become broadly trained, or they can choose to focus their studies and select either the Biomedical Sciences and Health Professions concentration or the Ecology concentration.  All three options provide flexibility to students to craft a curriculum that fits their interests while still providing essential instruction in the life sciences, physical sciences, and mathematics necessary for success as a Biologist.

Students must complete at least 39 credit hours of 300-400 level courses.  All Biology courses level 300 and above are accessible only after students successfully complete BIO 125, BIO 125L, BIO 126, BIO 126L with a C- or better, and pass the Biological Foundation Proficiency Exam, which assesses mastery of the material from Biological Principles I and Biological Principles II.  This requirement includes transfer students.

All Biology majors must take General Education and Science Foundation courses.  These courses include:

University Campus Only Course Requirements

University Explorations (42 credit hours)

Foundation Courses (26 credit hours)

General Biology Specialization

The General Biology Concentration is designed to provide students with a well-rounded understanding of Biology.  Students are required to complete 38-39 concentration credit hours.

Biomedical and Health Sciences

The Biomedical and Health Sciences Concentration will prepare students for graduate and professional school in the biomedical and health sciences.  Students are required to complete 35 concentration credit hours.


The Ecology Concentration is intended to provide students with the opportunity to focus their studies on hands-on understanding the function of biological systems beyond the scale of single organisms.  Students are required to complete 38 concentration credit hours.

General Elective Credits: Complete enough general elective credit hours to fulfill total hours required for degree completion.

Total Credits: 120
