The Major

Biology!The Biology major provides students with a broad base for understanding principles governing life processes at all levels–molecular, cellular, organismal, and ecological. An evolutionary perspective guides all areas of the curriculum–development, behavior, physiology, genetics, and more.

The Biology major is satisfied by nine courses:

Required Core Courses

  • BIOL 101 (F) The Cell
  • BIOL 102 (S) The Organism
  • BIOL 202 (F) Genetics

A student who places out of BIOL101 and/or BIOL102 (by passing the First Days placement exam) must still take nine BIOL courses to complete the BIOL major.


  • two 300-level courses; both of which must have an associated laboratory
  • one 400-level course
  • three additional Biology electives at the 200-level or higher

Please note the following:

  • At least one elective must cover biological processes at levels of organization above the cell (indicated in the course description as “satisfies departmental distribution requirement”)
  • The two courses CHEM 156 and 251 can be counted as one of the electives for the BIOL major. However, the College does not allow the same course to count toward fulfilling the requirements for two majors (“no double-counting”). This means that if you are a BIOL and CHEM major, you cannot count CHEM 156 and CHEM 251 as an elective toward the BIOL major.
  • Some BIOL courses do not count toward the BIOL major (so-called “non-majors” courses) (for ex., BIOL 132, 133, and 134).

Research Courses

Students can take research courses (BIOL297, 298, 493, or 494) for academic credit. In addition, students can enroll in a WSP course to do research on campus (BIOL 21) or carry out an off-campus research internship (BIOL 22 or a WSP99 project). Independent research is not required for completion of the major–however, students thinking of attending graduate school are strongly advised to pursue at least one semester of independent research.

A research course can count as an elective; however, only one semester of research can count toward the nine courses required to complete the major. Research courses do not satisfy the 300- or 400-level requirements for the major.

The Major with Honors

The Biology Major with Honors consists of 10 courses plus a required WSP course. In addition to the requirements listed above for the BIOL major, honors students carry out a year-long independent research project (by enrolling in BIOL 493, 031, and 494) that culminates in a written honors thesis.

Enriching Your Biology Major Experience

  • Majors are strongly advised to take two semesters of chemistry, a statistics course, calculus, and physics.
  • Majors should take courses in related disciplines such as geosciences, chemistry, anthropology, cognitive science, neuroscience, mathematics, physics, bioinformatics, public health.
  • Consider a concentration in an interdisciplinary program such as ENVI, NSCI, BIMO, Public Health, or other related programs in the sciences.
