Biology is the science of living organisms, including their structure, function, growth, origin, evolution, and distribution. If you are interested in ecology, genetics, microbiology, or cellular, developmental, environmental, or molecular biology, and want to develop a foundation in biology while also exploring other academic disciplines, the Biology B.A. degree may be a good choice for you.
The Department of Biology is part of the College of Arts and Sciences and includes expert faculty who specialize in a wide range of disciplines within the biological sciences. When pursuing a biology major, you work with faculty who are conducting ongoing cutting-edge research in biology, giving you the opportunity to participate in some of the latest scholarship in the field.
The Department of Biology offers two biology degrees: the Bachelor of Arts in Biology (B.A.) and the Bachelor of Science in Biology (B.S.). The two degree options begin similarly, making it easy to adjust your path as your interests develop.
The Biology B.A. is the most flexible degree offered by the Department of Biology. It provides students with training in the major subject areas of biology, while giving them the chance to explore other academic disciplines. The Biology B.A. has minimal chemistry and math requirements, giving you the opportunity to earn a double major or pursue additional minors.
The Biology B.A. degree does not automatically fulfill most of the requirements for entrance to medical, dental, or optometry schools or to most graduate programs in biology. If you desire to establish a rigorous background in the sciences that will prepare you for graduate or professional school for science-related jobs, the Biology B.S. degree may be a better option for you.
Biology majors begin by taking two introductory Biology lecture courses:
- BIOL-L 111 Foundations of Biology: Diversity, Evolution, and Ecology
- BIOL-L 112 Foundations of Biology: Biological Mechanisms
These are followed by BIOL-L 113, the introductory Biology Lab.
It is important for you to begin the chemistry sequence required for the Biology B.A. major in your first or second year, since a foundation in chemistry is required for a majority of intermediate and upper-level biology courses. You may work with one of the Biology academic advisors to determine which beginning chemistry course is appropriate for you (either CHEM-C 103, or CHEM-C 117 together with CHEM-C 127), or you can check your CHEM-C 117 eligibility yourself on the website for the Department of Chemistry.
To be successful in the Biology B.A. major, it is important to limit the number of science and math courses that you take each semester. Talk with one of the academic advisors about how to balance your science course load.
Tracks and concentrations
The beauty of the Biology B.A. degree is that it gives students the opportunity to explore different areas within the field of biology as well as other academic disciplines. As a Biology B.A. major, you will have the freedom to take upper-level courses from many different areas of biology while shaping your degree according to your interests.
The Biology B.A. does not have official areas of concentration, but students who are interested in one of the following areas may choose to take upper-level classes from within that area:
If you take several upper-level biology courses within one of the above areas, you will acquire a more coherent education in a specific area of biology. Your introductory courses will help you determine which (if any) area of interest to pursue.
Upper level coursework
All Biology majors complete 18 to 20 credit hours of core classes in biology, which include courses such as molecular biology, genetics, and evolution. Keep in mind that you will need a strong foundation in inorganic and organic chemistry in order to successfully progress through your intermediate and upper-level biology courses.
Biology students get to choose many of their upper-level biology courses. Upper-level biology lectures and labs are offered in the following subject areas: microbiology, biotechnology, biochemistry, cell biology, ecology, the environment, botany, and zoology. See the comprehensive list of approved upper-level lectures and labs for course titles.
Students interested in continuing their education overseas may want to participate in the tropical biology overseas study program led by IU Biology faculty members. The program is held in Costa Rica over winter break and in the Cayman Islands in the spring. You get credit for one upper-level biology lab by participating in one of these programs. Talk to an Overseas Study advisor or visit the Overseas Study website for more information.
Commonly pursued majors, minors and certificates
With the help of your academic advisor, you may be able to combine several areas of interest with additional majors, minors, or certificates. Biology B.A. majors most commonly pursue the following additional degrees: Psychology, Animal Behavior, English, Anthropology, Environmental and Sustainability Studies, Human Biology, and Spanish.
Common minors for biology students include psychology, animal behavior, chemistry, social science and medicine, medical sciences, biotechnology, anthropology, and Spanish (or another language). Check your bulletin for more information about these minors.

Working with faculty
When pursuing a degree in Biology, you have the opportunity to work with faculty who have expertise and experience in the field. Take advantage of office hours to talk with your instructors about your performance in class, the content of assignments, and how the course helps you work toward your goals.
Many exciting research opportunities are available to biology majors at IU Bloomington. Interdisciplinary research in biology and microbiology takes place in Indiana University facilities such as the Biocomplexity Institute, the Center for the Integrative Study of Animal Behavior (CISAB), and the Center for Genomics and Bioinformatics. The nearby Research and Teaching Preserve provides a setting for field-based research in ecology and environmental issues.
Many students choose to pursue research positions in faculty labs. Through working in a lab, you get to participate in cutting-edge research, explore your own research interests, build relationships with faculty members, and gain valuable work and research experience.
Students can receive academic credit for their involvement in research by signing up for BIOL-X 490 Independent Study credit hours. See the Biology Department's website for more information on ways you can earn independent study credit.
Undergraduate Research Programs such as ASURE, the Integrated Freshman Learning Experience (IFLE), Science, Technology, and Research Scholars (STARS), and the Cox Scholars Program give students who are especially interested in research the opportunity to start working in a lab as early as their first year. Students in IFLE begin research in the summer before their first semester at IU.
You are encouraged to work with a faculty member who specializes in what most interests you. For more information about the exciting research underway in the Department of Biology, visit the faculty and research webpages. The academic advisors post relevant research opportunities on the Undergraduate Biology blog.
Biology majors have the opportunity to gain teaching experience by becoming an Undergraduate Teaching Assistant (UTA). Introductory biology courses, especially BIOL-L 111 and BIOL-L 112, are large classes with discussion groups; UTAs help to create a small class atmosphere inside a large course. Students may either earn academic credit or be paid for their UTA experience.
Outstanding students may earn honors in biology by writing and defending an honors thesis on their own original research. Students work with a faculty mentor to develop a research project, assemble a thesis committee, and write their thesis.
To be eligible for departmental honors, students must have conducted their own research over at least two semesters and earned at least 6 credits of BIOL-X 490 devoted to their original project. Students who successfully complete and defend their honors thesis before their thesis committee receive honors in biology upon graduation. Talk with the academic advisors and the Biology faculty for more information.
