BIOL 103 Biology in Science Fiction
Credit: 0.5 QR
Science-fiction literature and film extend our awareness of the natural world in amazing ways, as in the film Avatar.Yet real biology is often more amazing than science fiction. The impact of evolution on human existence is examined through Wells's The Time Machine and Vonnegut's Galapagos, while bizarre living creatures are explored through Herbert's Dune and Crichton's Jurassic Park. Quantitative reasoning in biology is introduced through problem sets applying calculation to extrapolate present and future biological phenomena. Exponential functions are used to explore whether human populations will explode, as in Star Trek, "The Trouble with Tribbles," or decline as in The Time Machine. Hardy-Weinberg equilibria and computer modeling show how bizarre mutant traits spread through populations, as in Galapagos. Acid-base titrations show how global warming acidifies the ocean, disrupting the marine ecosystem as in Slonczewski's A Door into Ocean. Students create their own interactive projects on the Web. May be offered in alternating years. No prerequisites. Does not count toward the major or minor.
Instructor: Slonczewski
BIOL 104 Biology of Female Sexuality
Credit: 0.5
This course examines the human female body with respect to sexual response, menstruation, reproduction, menopause, and contemporary health issues. Students work in cooperative learning groups for leading discussions and for the class praxis project, which focuses on constructive alliances with men to promote healthy relationships and reduce the sexual objectification and rape of women. The underlying goals of the course are to provide an anatomical appreciation of the human body, to improve our capacity to act as informed health-care consumers, to forge a feminist understanding of women's health concerns in a social context, and to learn skills for bridging differences and for networking among women in their diversity, in order to provide better health care for all. Texts vary from year to year. This course no longer has a laboratory component. There are no prerequisites. Men are welcome. This course counts toward the women's and gender studies major but does not count toward the biology major or minor.

BIOL 107 Scaling in Biology: Why Size Matters
Credit: 0.5 QR
While biologists seek general principles that explain the common characteristics of all organisms, we too often ignore that most obvious of traits: an organism's size. We will explore how size determines the form, function, pace, and complexity of life. Our questions will span realms from the miniscule (can bacteria see?) to the gigantic (how many species are there on Earth?) to the fantastic (what would it cost to feed King Kong?) Living things span an amazing range of sizes, and by studying the importance of size in the living world, we will develop a quantitative framework for comparing not just apples and oranges, but bacteria and blue whales. Surreal perspectives on biology such as Swift's Gulliver's Travels, and Kafka's Metamorphosis, as well as films like A Fantastic Voyage and Destroy All Monsters, will further highlight the truly amazing nature of biological reality. This course has no prerequisites.

Credit: 0.25-0.5
This course provides the student with the opportunity to pursue an independent investigation of a topic of special interest not covered, or not covered in depth, in the current curriculum. The investigation, designed in consultation with the chosen faculty mentor, may be designed to earn .25 or .5 unit of credit in a semester. BIOL 393 is ordinarily a library-oriented investigation. (For laboratory-oriented independent research, see BIOL 385 and 386.) Normally, students receive credit for no more than two semesters of independent study. Independent study does not count toward diversification requirements for the biology major.
BIOL 493 Independent Study in Biology
Credit: 0.25-0.5
Individual study in biology, typically pursued by juniors or seniors, provides an opportunity to pursue an independent investigation of a topic of special interest not covered, or not covered in depth, in the curriculum. The investigation, designed in consultation with the chosen faculty mentor, may be designed to earn .25 or .5 unit of credit in a semester and may be continued in the second semester. BIOL 393 ordinarily involves literature-oriented investigations. (For laboratory-oriented independent research, see BIOL 385 and 386). Normally, students receive credit for no more than two semesters of individual study. Such study cannot be used to fulfill either the natural science diversification requirement or the requirements for the major. To enroll in individual study, a student must identify a member of the Biology Department willing to mentor the project and, in consultation with him or her, draft a syllabus, including readings, a schedule, and assignments, which must be approved by the department chair. The student should meet regularly with the instructor for at least one hour per week or the equivalent. The amount of graded work should approximate that required, on average, in 300-level biology courses, at a minimum. In the case of group individual studies, a single course syllabus may be submitted, assuming that all group members will follow the same syllabus. Students are urged to begin discussion of their proposed work well in advance, preferably the semester before, so that they can devise a syllabus and seek departmental approval before the registrar's deadline.
