Biology is the study of living systems and is the broadest biological sciences major available at KU. The B.A. Biology degree provides students with much flexibility in their major course choices and can include ecology, microbiology, organismal physiology, and biochemistry.
Admission to KU
All students applying for admission must send high school and college transcripts to the Office of Admissions. Unless they are college transfer students with at least 24 hours of credit, prospective students must send ACT or SAT scores to the Office of Admissions. Prospective first-year students should be aware that KU has qualified admission requirements that all new first-year students must meet to be admitted. Consult the Office of Admissions for application deadlines and specific admission requirements.
Visit the International Support Services for information about international admissions.
Students considering transferring to KU may see how their college-level course work will transfer on the Office of Admissions website.
Admission to the College of Liberal Arts and Sciences
Admission to the College is a different process from admission to a major field. Some CLAS departments have admission requirements. See individual department/program sections for departmental admission requirements.
First- and Second-Year Preparation
Because biology study requires preparation in other sciences, students should begin meeting major requirements in the first year. It is particularly important to take CHEM 130 and CHEM 135 in the first year and, for several majors, to take CHEM 330, CHEM 331, CHEM 335, and CHEM 336 in the second year. Ideally, most majors should also take BIOL 150 and BIOL 152 during the first year, as well as BIOL 105.
Majors and Concentrations
Bachelor’s degree requirements in biology are modified as necessary. Current requirements are available in the UBP office and online. Major programs are offered in biochemistry, biology, human biology, and microbiology. Students may choose to concentrate in a range of specialties in the biological sciences, such as botany, cellular biology, developmental biology, environmental biology, ecology, entomology, genetics, marine biology, molecular biology, neurobiology, paleontology, physiology, systematics, or zoology (invertebrate or vertebrate).

The BA requires completion of two courses of collegiate-level writing instruction. Students who test out of Composition will still need to complete ENGL 102 (or equivalent) and one additional Goal 2.1 course.
Requires a Math ACT Score of 26+, a comparable SAT or KU Math Placement Exam score, or credit for MATH 101 or MATH 104 equivalent course. MATH 125 can be taken instead of MATH 115 and MATH 116 to fulfill the math requirement.
Concurrent or prior enrollment in CHEM 130 is required.
10 credit hours of BIOL 400+ level courses, including at least 4 hours of lab credit. See the degree requirements page in the catalog for limits on using BIOL 423 and/or BIOL 424 for this requirement.
BIOL 599 is approved to fulfill Goal 6. This goal can also be fulfilled by completion of an approved educational experience, or an approved integration of courses and/or experiences. See your advisor for more information.
Visit this website for a list of courses that fulfill the BA Quantitative Reasoning requirement.
BIOL 105: Biology Orientation Seminar (1 hour online course) is required for the major. It can be taken the summer prior to your freshman year.
All students in the College of Liberal Arts and Sciences are required to complete 120 total hours of which 45 hours must be at the Jr/Sr (300+) level.
The same course cannot be used to fulfill more than one KU Core Goal. However, overlap of a KU Core course with a major or degree-specific requirement is allowed. Overlapping is recommended to allow more opportunities to explore other majors and/or minors.
Undergraduate majors are eligible to graduate with honors in biology if they fulfill the following requirements:
- Complete all course work required for the appropriate degree in biology.
- Achieve a minimum grade-point average of 3.25 overall and 3.5 in the major.
- Complete BIOL 499 Introduction to Honors Research with a grade of B or higher.
- Complete BIOL 699 Biology Honors Research Colloquium with a grade of B or higher.
- Complete an independent research project under the supervision of a faculty member in an area appropriate to the degree sought.
- Submit an honors thesis to the honors committee once the research is complete and present the results of the completed research at the honors research symposium.
Students majoring in Human Biology with Anthropology, Applied Behavioral Science, Psychology, or Speech-Language-Hearing concentrations will follow the honors requirements for their respective concentration department.
Specific guidelines and intent forms are available in the Undergraduate Biology Program office and online. Candidates must declare their intent to graduate with honors at least 2 semesters before graduation.
Consult an advisor at least 4 months before undertaking study abroad. Consult the Office of Study Abroad, 108 Lippincott Hall, for information about study in one of the many countries (e.g., Scotland, Australia, Switzerland) with special arrangements with KU.
