Biology, (B.S.)

Students who earn a B.S. in Biology should attain the following objectives: (a) demonstrate knowledge and comprehension of the principles, concepts, and theories pertinent at each level of biological organization; (b) apply principles of biological classification to the diversity of life and recognize phylogenetic relationships among organisms; (c) demonstrate skills in analytical reasoning and problem solving; (e) function successfully in laboratory and field settings, including the use of basic equipment, techniques, and safety protocols; (f) access, evaluate, and utilize biological information in print and electronic formats; (g) effectively communicate scientific knowledge and experimental results in both oral and written formats; (h) compete successfully for admission to graduate and professional programs and for employment utilizing their academic training.

University General Education Program (41 hours)

See Graduation from the University  for the University General Education Program requirements.

Note: Biology majors are also required to take either MATH 1830  or MATH 1910  and these courses will fulfill general education requirements.

Eight credit hours of natural science courses (two lectures with labs) are required for general education and can be fulfilled by the following courses that are required for the Biology major. 

The Major (67-68 hours)

Biology Requirements (18 hours):

Additional Science and Math Requirements (27-28 hours):

18 Additional Upper Division Hours in BIOL Courses Approved by the Department Including One Organismal Diversity Course From Among:

Required Support Courses:

Select courses from each of the following three areas for a total of 12 hours:

Skills Courses (two courses):


Electives must be chosen to bring the total number of hours to 120.


Students must earn a grade of at least “C-” in CHEM 1110  and CHEM 1111   before taking any biology courses. 

Students must earn a grade of at least “C-” in all BIOL courses applied toward the major, the minor, and in all required chemistry, physics, and mathematical courses. BIOL, CHEM, MATH, and PHYS courses applicable toward the major or minor may not be taken more than three times.

Students must earn a grade of at least “C-” in BIOL 1110  / BIOL 1111  and BIOL 1120  / BIOL 1121 , before enrolling in any upper division BIOL course.

Any BIOL course applicable toward the major or minor may be repeated once to earn a minimum grade of “C-.” To repeat a course a second time, a student must apply for and receive special permission from the department Undergraduate Studies Committee. Application information is available in the Biology Advising and Resource Center.

A student may not attempt the same BIOL course more than three times, regardless of where it is taken. Courses cross-listed with BIOL (e.g., CHEM 4511 CHEM 4512 , and CHEM 4501 ) also are subject to this course repetition policy.

No more than five total credit hours of experiential learning courses (BIOL 4000 , BIOL 4001 , BIOL 4005 , BIOL 4098 Special Topic: BIOL Learning Assistant, BIOL 4570 ) can be applied toward major requirements.
