Courses in the biological sciences at Princeton are offered in two departments. Students with an interest in whole-organism and large-scale processes--evolution (including molecular evolution and developmental evolution), physiology, disease, behavior, neuroscience, ecology, ecosystem biology, conservation, and climate change--should enroll in the Department of Ecology and Evolutionary Biology (EEB). Those with interests in molecular, cellular, and developmental processes should enroll in the Department of Molecular Biology (MOL). Both departments provide an excellent background for medical school.
The EEB department emphasizes research and teaching from an evolutionary perspective, combining theory and empiricism and linking areas that are often treated as separate disciplines. Many of the research projects and courses are interdisciplinary. A description of these core areas, faculty interests, and unique features of the program, including details about the department's field programs, can be found on the department's website.
Every student considering majoring in EEB should attend the departmental open house held in the spring term. It introduces potential majors to departmental courses, faculty, and the wide-ranging research and field-course opportunities open to students. See the department's website for examples of recent student research activities.
Advanced placement will be granted to students who received a 5 on the Biology AP exam. This excuses EEB majors from taking 211.
The Department of Ecology and Evolutionary Biology requires the following prerequisites of its concentrators:
- Mastery of calculus to the level of MAT 102 or 103, or advanced placement (an AP score of 5 on the AB test or an AP score of 4 on the BC test);
- Two terms of introductory chemistry (or equivalent, or an AP score of 5);
- The first term of introductory physics (or the equivalent, or an AP score of 5; note that medical schools require two terms; physics can be delayed to the junior or senior year if necessary);
- An introductory statistics course (EEB 355 is preferred and counts as a departmental; other appropriate, but non-departmental, courses are: ECO 202; ORF 245; POL 345; PSY 251; or SOC 301);
- Two terms of introductory biology (an AP score of 5 can substitute for EEB 211, but not the second introductory course chosen, either EEB/MOL 214 or EEB/MOL 215).
Students who are passionate about solving problems in the areas of ecology, evolution, behavior, conservation, and disease may apply for early concentration in ecology and evolutionary biology. Students having advanced placement in biology and having taken at least one upper-level EEB course, in addition to having completed many of the department's required pre-and co-requisite courses with grades of at least B+, are eligible. Early concentrators will begin independent work during the spring of their sophomore year. Exploration of an interesting problem will commence with an intensive reading course culminating in the development of a research project that will be carried out in the laboratory, or at a field site, of a faculty mentor. Students interested in early concentration should contact a departmental representative at the end of the freshman year or at the start of the sophomore year.
Requirements. The following courses are required for graduation:
1. Students in ecology and evolutionary biology must successfully complete at least eight upper-level departmental courses, five of which must be EEB or MOL courses. One of the eight must be a lab course; 314, 324, 417B, and all field courses count as lab courses.
Choice of Courses. Students must take at least one course from each of the following three general areas:
Behavior and Physiology: 301, 311, 314, 323, 350, 404, PSY 315;
Evolution and Genetics: 309, 320, 360, 414, MOL 342;
Ecology and Conservation: 308, 312, 321, 322, 324, 328, 338, 346, 352, 380, 417.
2. Organic chemistry: CHM 301 or 303; (Students interested in mathematical biology may take one of the following courses instead of organic chemistry: PHY 203; MAT 200, 201, 202, 203, 204; COS 126, 226);
Students may take 309, 321, and 323 in the fall term of junior year to sample all three areas. Pay particular attention to the timing of the courses that are taught in alternate years.
No course taken pass/D/fail can be counted as a departmental. The minimum grade for a course to count as a departmental is C-. Only one course with a policy perspective can be counted as a departmental. Only Princeton courses can count as departmentals; the one exception is for pre-approved courses taken during a study abroad term.
Special Features of the Plan of Study. EEB offers three tropical field study programs: a semester in Panama, a semester in Kenya, and a summer in Bermuda. Details of these programs can be found on the department's website.
Specializations. Because some EEB students are interested in specializing within the department, EEB offers several areas of focus, the most common of which are listed below with their relevant courses.
Theoretical biology: 309, 320, 321, 322, and 324;
Field biology: 309, 311, 321, and a tropical field program;
Conservation biology: 308, 309, 311, 321, 323, 417, and a tropical field program;
Medical biology: 309, 311, 314, 321, 323, 327, and 328;
Human biology: 301, 306, 309, 315, PSY 330, and 336.
Note: MOL 214 is required for medical school. A full year of physics is required for medical school and by some graduate programs (especially in neurobiology). A full year of organic chemistry is required for medical school, and is a prerequisite for many molecular biology courses; the second term also counts as an EEB departmental. At least one term of organic chemistry is usually required by graduate programs in biology. Completing the organic chemistry requirement before junior year is strongly recommended.
Junior Independent Work. Students attend a weekly junior tutorial in the first half of the fall term. Faculty members present summaries of their work and research opportunities open for senior independent work. During the second half of the fall term, students work closely with one faculty member to investigate a problem using the current literature, and then write a paper. In the spring semester, students carry out a program of independent work with a faculty adviser. In some instances this may include empirical or theoretical work. Either a paper summarizing this project or a research proposal for the senior thesis is due in early May.
Senior Independent Work. During the fall of the junior year each student selects a senior thesis adviser. The adviser and the student choose a research project that the student generally pursues during the summer preceding the senior year and both terms of the senior year. The research project can involve primarily laboratory, field, data mining, theoretical, or library study that will be written and presented as a senior thesis.
A one-hour oral examination, consisting of a defense of the thesis research and general questions in the biological sciences, and a poster session, will be held in May.
Tropical Field Programs. Students interested in learning about or undertaking research in the tropics have a number of options.
1. Panama. The department offers a spring term in Panama in conjunction with the Smithsonian Tropical Research Institute. Students take four intensive three-week courses in sequence, beginning with an introduction of key concepts in tropical ecology and conservation, followed by a course that incorporates extensive field trips and research projects. The program continues with an anthropology course and a final three-week course on a particular aspect of tropical biology. Prerequisite: EEB 321.
2. Kenya. This four-course program, also taught in three-week segments, takes place at Princeton University's Mpala Research Centre in central Kenya and other sites in Kenya, in collaboration with scientists there, EEB faculty, and other appropriate faculty from Princeton University. The courses delve into conservation in Africa, restoration ecology, the natural history of mammals, and global technology and engineering. Prerequisite: EEB 321.
3. Bermuda. During June, the department, along with the Bermuda Institute of Ocean Sciences, offers Marine Biology. This four-week course focuses on the ecology, physiology, and behavior of marine organisms, particularly from the coral reef. Almost half of the labs involve field trips to the reefs or intertidal zone. Prerequisite: EEB 211.
4. Other. Individual students are welcome to pursue other independent field opportunities, with scientists from the Smithsonian Institution and the Bermuda Institute of Ocean Sciences, or other research institutions, such as the School for Field Studies at the University of Cape Town, South Africa, or James Cook University in Australia.
Program in Teacher Preparation. As the need for qualified science teachers increases, some students may wish to earn a teaching certificate. Working with the departmental representative and the teacher preparation program, an appropriate course of study can be arranged.
