Majors, Minors, & Honors in Biological Sciences

Majors and Minors Offered

The Biological Sciences Department offers three majors:
  • Biological Sciences (BioSci), for the student seeking a broad base in the biological sciences, though it is a highly flexible program that allows a certain amount of specialization in upper-level courses;
  • Ecology, Evolution and Organismal Biology (EEOB), for the student with an interest in ecology, evolutionary biology, environmental biology, and conservation biology;
  • Molecular and Cellular Biology (MCB), for the student with an interest in developing an in-depth understanding of how living systems function at the molecular and cellular levels, with upper-level course options ranging in content from biophysics and biochemistry to developmental biology, and to molecular aspects of evolution and of toxicology.

The department offers a minor in Biological Sciences for students majoring in other disciplines.

Double majors and minors in other departments:

With planning, it is possible to combine a major in Biological Sciences with another major. While it is more common for double majors to consider related fields such as chemistry and mathematics, students have combined Biological Sciences majors with such diverse areas as foreign languages, music, and fine arts. Consult the Director of Undergraduate Studies as early as possible.

Double or triple majors entirely within the Biological Sciences department are not permitted.

Requirements for a Major

General requirements for all three majors:

  • Two semesters of general chemistry and lab (Chemistry 102a,b and 104a,b) and two semesters of organic chemistry and lab (Chemistry 219a,b and 220a,b);
  • It is strongly recommended that students in all three majors take one year of calculus or calculus/statistics and one year of physics;
  • A total of 30 hours of Biological Sciences courses, including the 8 hours of 110a,b and 111a and either 111b or 111c, are required in all majors. All Biological Sciences courses count toward the major except 100, 105, 115F;
  • Students with specialized interests within either of the specialized majors may substitute one of the intermediate courses with an upper level course with the permission of the Directors of Undergraduate Studies and the Biological Sciences Curriculum Committee. Intermediate Biological Sciences courses are 201, 202, 205, 210, 211, 218, 219, 220, 237, 238;
  • Students may declare only one of the majors offered by the Department of Biological Sciences. Double or triple majors within the department are not permitted;
  • Below is a listing of the required courses for the Biological Sciences (BSCI) major, for the Molecular and Cellular Biology (MCB) and for the Ecology, Evolution & Organismal Biology (EEOB) major.

Requirements for a Minor

Requirements:

A minor in Biological Sciences (BSCI) requires a minimum of 18 hours that include BSCI 110a,b; 111a and either 111b or 111c; 210; and one other intermediate course. No more than two credit hours of 280, 282, 283 or 286 may be counted toward the minor.

Minors are usually taken either to extend the student's interest in biological sciences, or to provide contrast. It should be noted that most minors can be easily accommodated if they are started in good time. Please contact the Director of Undergraduate Studies for more information.
