Biologists seek to understand the living world in all of its complexity through scientific methods of inquiry. The Department of Biology is made up of a group of committed faculty members with expertise in diverse fields and sub-disciplines. Our curriculum provides majors with opportunities to explore the full breadth of biological organization and provides experiential learning opportunities that enhance students’ understanding of content and techniques, as well as the strengths and limitations of scientific methods of inquiry.

The Biology curriculum is designed to give students a strong background in fundamental concepts of biology at the cellular, organismal, and population levels as well as the tools for understanding and carrying out biological research. Student-generated investigations are built into the structure of courses throughout the Biology curriculum beginning in the Gateway courses and continuing through Independent Study. Students collaborate and communicate with peers and faculty as they progress through their courses and Independent Study. These opportunities develop students’ oral and written communication skills as well as their capacity for self-education and problem-solving. These abilities, combined with a liberal arts education, are essential for remaining competitive in the rapidly developing life sciences.

Through its curriculum, the Biology Department seeks to develop students who:

  • comprehend foundational and unifying biological principles and their implications;
  • retain the knowledge essential to a broad understanding of Biology;
  • are familiar with scientific methods of inquiry and the philosophy of science, including methodologies for distilling biological information;
  • are able to design and conduct an independent scientific investigation;
  • can use scientific information to make reasoned decisions and critically evaluate the work of others;
  • are able to communicate scientific information effectively;
  • show evidence that they understand how knowledge changes; and
  • are motivated to think, study and learn independently.

Special Notes


  • The Breadth Requirement: As noted above, Biology majors should possess broad, foundational knowledge of biology. Students are introduced to a diversity of biological topics in our introductory course sequence (BIOL 11000 BIOL 12000 , and BIOL 13000 ) and then develop additional depth in each subdivision by completing at least one 200-level course from two of the three major subdivisions, as organized below. Students are strongly recommended to complete the breadth requirement before beginning BIOL 40100  so that they can incorporate a range of biological concepts and tools into their Independent Study thesis project.

Molecular and Cellular Biology
BIOL 23000 - Genes and Genomes 
BIOL 23100 - Microbiology

BIOL 39907 - Computational Genomics 
BCMB 30300 - Techniques in Biochemistry and Molecular Biology 
BCMB 33100 - Principles of Biochemistry 
BCMB 33200 - Biochemistry of Metabolism 
BCMB 33300 - Chemical Biology  

 

Ecology, Evolution, and Organismal Biology
BIOL 21000 - Natural History of the Vertebrates 
BIOL 21100 - Natural History of the Invertebrates 
BIOL 21200 - Field Botany 
BIOL 21300 - Conservation Biology 
BIOL 31000 - Population and Community Ecology 
BIOL 31300 - Animal Behavior 
BIOL 31400 - Evolution 

 

Physiology and Organismal Development

BIOL 22100 - Comparative Animal Physiology 
BIOL 22200 - Cellular Neuroscience 
BIOL 32000 - Behavioral Endocrinology 
BIOL 32100 - Sensory Biology 
BIOL 32200 - Developmental Biology 

 
  • When possible, CHEM 11200  should be completed in the first year, since it must be taken before or with BIOL 20100  and is a prerequisite to several 300-level Biology courses.
  • The introductory courses (BIOL 11000 BIOL 12000 , and BIOL 13000 ) may be taken in any order but must be completed before enrolling in BIOL 25000 .
  • One introductory course is the prerequisite to each 200-level course, although a student may be admitted to a 200-level course by permission of the instructor without the prerequisite, when justifiable.
  • BIOL 25000 - Research Skills for Biology  should be taken by prospective Biology majors in the fall or spring of their sophomore year.
  • BIOL 25000  does not count as a 200-level elective toward the Biology major.
  • BIOL 25000  must be completed before beginning Introduction to Independent Study (BIOL 40100 ).
  • Students should take as many biology courses as possible, but at minimum all required 100-level courses, two 200-level courses, and one 200-level laboratory course must be completed before beginning BIOL 40100 
  • BIOL 40100  must be completed before the student enrolls in BIOL 45100 , and is normally taken in the second semester of the junior year. Students planning a semester off campus should consult with a Biology adviser early in the planning stage (see below).
  • The Biochemistry and Molecular Biology courses (BCMB 30300 , BCMB 33100 , BCMB 33200 , BCMB 33300 ) count toward the Biology major and minor and are considered Biology courses for purposes of determining departmental honors. BIOL 10000  and BIOL 40000  courses do not count toward the major or minor, nor do they apply to Honors calculations.
  • Biology majors contemplating graduate or professional school are strongly encouraged to take a full year of Organic Chemistry (CHEM 21100 , CHEM 21200 ), a full year of general physics (PHYS 10700 , PHYS 10800  or PHYS 11100 , PHYS 11200 ),  BCMB 33100 - Principles of Biochemistry   AND at least one course in calculus.
  • Laboratory Grade Policy: Some Biology courses have an associated laboratory section. Unless laboratory sections are marked as optional in the course description, students should enroll in both the lecture section and the laboratory section of a course simultaneously. Whether the laboratory section is graded separately or included.as a portion of the lecture section grade is left to the discretion of the instructor.
  • Advanced Placement: Students receiving a score of 5 on the Advanced Placement Examination in Biology will receive credit for Foundations of Biology (BIOL 11100 ). With a score of 4 on the Biology AP exam a student can receive one course credit in BIOL 10000 - Topics in Biology , or upon successful completion of the Biology Placement exam may receive one course credit for Foundations of Biology (BIOL 11100 ). Advanced placement credit cannot be substituted for any other Biology courses than those specified above. To receive appropriate Biology credit for AP scores, please contact the Chairperson of the Biology department. The advanced placement policy of the College is explained in the section on Admissions .
  • Off-Campus Study: Off-campus study can be a valuable and enriching part of the college curriculum, and we encourage our students to consider off-campus study as a means of augmenting and enhancing their study of biology. Students who would like to include this in their program of study are encouraged to talk with a departmental faculty member early in their first year, and to think about scheduling choices that would make this possible. Off-campus study is best scheduled for the Spring of the sophomore year or the Fall of the junior year. Biology courses taken at other institutions may count toward the major for up to two 300-level courses. Students should discuss their proposed course electives with the department chair prior to their study-abroad experience (or prior to enrolling in courses at other institutions), to determine whether the courses are equivalent to Wooster courses, and whether they will count toward the major.
  • Non-Science Majors: Biological information has become increasingly important as citizens face crucial decisions on such issues as the environment, emerging diseases, genetic engineering, and our aging population. To gain an appreciation of how biologists approach and understand life processes, non-science majors may enroll in either Topics in Biology (BIOL 10000 ) or a single 100-level Biology course. Topics in Biology (BIOL 10000 ) courses address specific topical issues in applied biology on a rotating basis (see catalogue description). BIOL 11000 BIOL 12000 , and BIOL 13000  are intended as entry courses for students considering a major in one of the Biological Sciences. For students interested in a more extensive laboratory experience, BIOL 20100  or BIOL 20200  would be appropriate after first completing BIOL 11100 .
  • A maximum of fifteen courses (including BCMB 30300 , BCMB 33100 , BCMB 33200  and BCMB 33300 ) from the Department of Biology may count toward the College’s thirty-two course graduation requirement.
  • Students are not permitted to count any courses taken for S/NC credit towards the major or minor.
  • A student must earn a grade of C- or higher for a course to count toward the major or minor.
