Biology courses deal with the science of living organisms in their various forms. The curriculum emphasizes the integration of all levels from molecular to ecological, with evolution as a unifying theme, and requires all seniors to complete a year-long research project. The department serves students who expect to work in a biological field or related profession such as medicine, as well as those who elect biology as part of a general education (see www.whitman.edu/biology).

A student who enters Whitman without any prior college-level preparation in biology will have to complete 50 credits, including courses in chemistry, mathematics, and biology, to fulfill the requirements for the biology major. Courses completed in this major apply to the science and quantitative analysis (selected courses) distribution areas.

The Biology major: A minimum of 33 credits in biology, including Biology 111, 112, 205, 206; four credits from each of the three categories of upper-level courses (Molecular/Cell Biology, Organismal Biology, Ecology/Evolution); 489; 490 or 498; 499; and additional courses in biology and/or BBMB courses numbered 200 or above to earn a minimum total of 33 credits in biology and/or BBMB. Chemistry 125, 126, 135, 136, or 140; 245; and demonstrated mastery of either two semesters of college calculus (Mathematics 125 and 126) or one semester each of college calculus and statistics (Mathematics 128 or 247, Biology 228, Economics 227, Psychology 210, Sociology 208). Departmental policy does not allow a P-D-F grade option for biology or BBMB courses that count toward the major.

The senior assessment consists of oral and written components. Oral component: a one-hour exam administered by a committee of biology faculty. Written component: Students must take the biology subject GRE and score in the 30th percentile or above.

The department recommends that students considering a major in biology consult with an adviser and begin with Chemistry 125, 126, 135, 136; or 140; Mathematics 125 and 126 or statistics; and Biology 111 or 112; Chemistry 245; Biology 205, 206. For those planning to pursue most graduate programs in biology, a year of physics (with labs), a full year in organic chemistry, a year of foreign language, as well as statistics and competency with computers are highly recommended.

The Biology minor: Biology 111, 112, and a minimum of eight additional credits in biology and/or BBMB courses numbered 200 or above. Departmental policy does not allow a P-D-F grade option for biology courses that count toward the minor.

The Biology-Geology combined major: Biology 111, 112, 205; four credits each from the Organismal Biology and Ecology/Evolution categories, and at least four additional credits in biology and/or BBMB courses numbered 200 or above; either Geology 110, 120, or 210; and 227; either Geology 312, Geology 321, or Geology 368; and 343, 346, 350, 470 and a minimum of one credit in 358; either three credits of Geology 480, 490, or 498 or three credits of Biology 489, 490, or 498; Chemistry 125, 126, 135, 136 or Chemistry 140; 245; Mathematics 125, 126 or statistics (Mathematics 128 or 247, Biology 228, Economics 227, Psychology 210, Sociology 208). Two semesters of physics and field experience are strongly recommended. Courses completed in this major apply to the science and quantitative analysis (selected courses) distribution areas.

The Biochemistry, Biophysics, and Molecular Biology (BBMB) major: See BBMB under the Courses and Programs section in the catalog for a description of the courses and major offered at the interface of biology, chemistry, and physics.

The Biology-Environmental Studies combined major: The requirements are fully described in the Environmental Studies section of the catalog. Courses completed in this major apply to the science and quantitative analysis (selected courses) distribution areas.
