1. Nine units:
   1. Chemistry 117, 220, 230, and 235.
   2. Biology 111, 121, 172, or 208.
   3. Biology 247 and Biology 237, 256, 257, or 289.
   4. Biology/Chemistry 260 and 300.
2. Two supporting units:
   1. Mathematics 110, 113, or 115.
   2. Physics 101 or 102 or Geology 100, 105, or 110.

The biology major provides a broad background in biology at all scales of organization, from molecules to cells to organisms to ecological communities.

1. Seven departmental units:
   1. One organismal biology course chosen from Biology 111, 121, 152, 172, or 208.
   2. Biology 247.
   3. Biology 289.
   4. Three additional units of biology courses numbered 200 or above.
   5. Capstone: one additional unit of biology numbered 301-389.
2. Three supporting units:
   1. One unit chosen from Chemistry 117, 150, 220, or 230.
   2. Two additional units chosen from courses in chemistry, computer science, geology, mathematics, physics or any of the following courses: Philosophy 100, Anthropology 230, 260, 330.

The environmental biology major provides a broad background in biology with a focus on how organisms interact with environments.

1. Six departmental units:
   1. One organismal biology course chosen from Biology 111, 121, 152, 172, or 208.
   2. Biology 247.
   3. Biology 289.
   4. Two additional units of biology courses numbered 200 or above.
   5. Capstone: one additional unit of biology numbered 301-389.
2. Four supporting units:
   1. One unit chosen from Chemistry 117, 150, 220, or 230.
   2. One additional unit chosen from courses in chemistry, computer science, geology, mathematics, or physics.
   3. Two additional units from Environmental Studies 205, 224, 255, 258, 280, 380, Journalism 225 (when topic is environmental writing), or Political Science 255.

The biology minor focuses on the mechanisms by which organisms regulate life processes, grow and develop, reproduce, and behave. 

1. Four departmental units.
2. One supporting unit chosen from chemistry, computer science, geology, mathematics, or physics.

Additionally:

1. The minor is not open to majors in biology, biochemistry, or applied chemistry (with biology as a complementary discipline).
2. No more than 2 units taken to satisfy requirements for a major or another minor may count toward the biology minor.
3. No course may satisfy two requirements for the minor.

Students may apply to be considered for departmental honors if they have:

1. a strong B average in BIOL courses,
2. have completed an independent research project equivalent to 1 unit, and
3. have made a formal public oral presentation on campus (e.g. Symposium Day, McNair Symposium) or a poster or oral presentation at a regional, national, or international conference; on-campus poster presentations and oral presentations in classes do not fulfill the presentation requirement.

No course may satisfy two requirements for a biology major.

Students who complete a biology major may graduate with the Bachelor of Arts degree. Students who wish to graduate with the Bachelor of Science degree must complete a minimum of 4 units in science and/or mathematics and/or computer science outside of the biology department.

Students anticipating graduate study or a medical career are urged to include the following courses in their undergraduate preparation:

1. Chemistry 117 or 150, 220, 230, 235
2. Mathematics 110 or 113, 115
3. Physics 101, 102

Additional courses (e.g. Chemistry 240, 245, 300 and Mathematics 175) may be appropriate for graduate work in biology. Many graduate schools and some professional schools require knowledge of a non-English language (e.g. Spanish, French, Japanese, or Russian) for admission to their programs.

Students anticipating careers in the health professions are strongly encouraged to complete Sociology 275, Philosophy 221, and 2 units in literature and composition. Depending on the specific goal of the student and the requirements of potential professional or graduate programs, various additional courses in the sciences and other departments may be relevant and appropriate.
