Aims of the Department
The objectives of the department are:
- to encourage the study of living organisms,
- to prepare biology majors in basic and advanced courses that provide a foundation for graduate study, teaching, and research in biology,
- to prepare pre-professional students in courses that satisfy entrance requirements for medical, dental, and veterinary medical school, and other professional programs,
- to prepare students anticipating careers in nursing and allied health fields,
- to prepare students seeking to fulfill general education lab science requirements, and
- to prepare students to respond intelligently to Creation/Evolution issues.
Programs
The department offers a Bachelor of Arts and a Bachelor of Science degree in biology. The B.A. degree requires 36 semester hours in biology and includes a foreign language component. The B.S. degree requires 40 semester hours in biology and emphasizes course work in biology and the sciences. Required cognate courses are specified for each degree. Southwestern Adventist University requires 40 hours of upper division credit for graduation; it is the responsibility of the student to meet that requirement through electives and general education requirements. The program has flexibility to allow students the choice of elective biology courses of special interest beyond the basic requirements listed below. It is highly recommended that students consult and follow the suggested class schedules found at www.swau.edu/academics/biology-and-geology
