   5. Three additional units of biology courses numbered 200 or above.
   6. Capstone: one additional unit of biology with the CP designation.

   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.
3. Students majoring in biology may choose to receive the Bachelor of Science degree rather than the Bachelor of Arts degree by completing a minimum of 4 units in chemistry, computer science, geology, mathematics, and/or physics.

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

1. Seven departmental units:
   1. One organismal biology course chosen from Biology 110, 111, 121, 152, 172, or 208.
   2. One experimental design and statistical analysis course: Biology 247.
   3. One molecular-to-cellular level course: Biology 289.
   4. One population-to-ecosystem level biology course chosen from 210, 217, 275 (in consultation with advisor, when topic is appropriate), 365, 372, or 375 (in consultation with advisor, when topic is appropriate).
   5. Two additional units of biology courses numbered 200 or above.
   6. Capstone: one additional unit of biology with the CP designation.
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 with the Environmental Studies prefix (ENVS), Journalism 225 (when topic is environmental writing), or Political Science 255.
3. Students majoring in environmental biology may choose to receive the Bachelor of Science degree rather than the Bachelor of Arts degree by completing a minimum of 4 units in chemistry, computer science, geology, mathematics, and/or physics.

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

1. Five departmental units.
   1. At least one organismal biology course chosen from: Biology 110, 111, 121, 152, 172, or 208.
   2. At least one unit of molecular-to-cellular biology chosen from: Biology 208, 215, 237, 256, 257, 260, 275 (in consultation with advisor, when topic is appropriate), 289, 300, 340, 345, 347, 360, or 375 (in consultation with advisor, when topic is appropriate).
   3. At least one unit of population-to ecosystem biology chosen from: Biology 210, 217, 365, 372, or 375 (in consultation with advisor, when topic is appropriate).
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 275) 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.
