Biology is the study of living systems and how they interact with the nonliving world and with one another. As such, biology is a discipline that bridges the physical and social sciences. Students who major in biology become familiar with all levels of biological organization from molecules to ecosystems, and gain practical experience in both laboratory and field studies.
Required for the major: four core courses (Biology 101s, 102, 170, and s42). Also required: five advanced courses (200 level or above); completion of the seminar and comprehensive examination requirements (see below); Chemistry 107, 108, and one of the following: Chemistry 203, 212, 218, Geology 363, or Biology 244. The Chemistry 218 option is recommended for students interested in attending graduate- or medical-school programs after graduation. No more than two research, thesis, or internship course credits, and no more than one Short Term unit credit (30 level or above) may be used to fulfill the requirement of five advanced courses. One of Chemistry 321, 322, Psychology 355, or 363 may be substituted for one advanced course in satisfying the requirements of the major.
Prospective majors are urged to discuss course scheduling with a member of the Department. A pamphlet describing curricular options in biology is available from the Department and is mailed, yearly, to all majors. Students may elect to include biological internships at a major research institution such as the Jackson Laboratory in Bar Harbor. Students are advised to complete the four required biology core courses before the end of their sophomore year in order to guarantee scheduling flexibility during the junior and senior years. Students are also encouraged to consider biology as part of an interdisciplinary program. Guidelines are available for individualized interdisciplinary programs in neuroscience. Students interested in interdisciplinary work in biochemistry should consult the catalog section titled Biological Chemistry.
General Education. A set in biology normally consists of any two of the following: 101s, 102, 158, 170, and s42 (please note that 170 and s42 have prerequisites). An upper-level biology course can be substituted for one of these five courses in order to complete a set. Only courses with associated laboratory components qualify for this kind of substitution, and any course prerequisites must be fulfilled before students will be allowed to enroll at an advanced level. Any biology course or Short Term unit may be used to fulfill the third course for the natural science requirement. The quantitative requirement can be satisfied by completing Biology 101s, 158, 170, 244, 255, or s45.
Comprehensive examination. The comprehensive examination requirement may be fulfilled by attaining a score corresponding to the twenty-fifth percentile on the Graduate Record Exam Subject Test in Biology. This exam must be taken on or before the December test date of the senior year. Students who have taken but do not pass the GRE by the deadline may fulfill this requirement by passing a departmental comprehensive scheduled during the Short Term of their senior year.
Seminar. Each major is required to attend eight of the departmental seminars (approximately twelve are scheduled each year), as well as the associated discussions by the second week in Short Term of the senior year. Discussions focus on a research paper describing the seminar speaker's work. No formal course credit is given for the seminar. Majors will be sent a full description of the program every fall.
101s. Biological Principles. An introduction to three fundamental areas of biology: the diversity of life, mechanisms of evolution, and genetics.

105. Life, Sex, and Cells. One of the great mysteries of the natural world is the prevalence of sexual reproduction. What, really, is sex? How did it begin? Why is it more common in species with complex cells and specialized bodies? Is sex required for reproduction in all of the millions of species, from bacteria to diatoms to mammals? What do "male" and "female" mean for asexual, hermaphroditic, and sex-changing species? This course takes a wide perspective to investigate the patterns of sex and gender among the species, assessing the traditional explanations--and their critiques--of the evolution and consequences of sex and gender. Enrollment is limited to 15 per section. S. Kinsman.
158. Evolutionary Biology. Evolution is the great unifying theory in biology. It is the context into which all other biological subjects fit.
