BS in Biological Sciences: Ecology and Evolutionary Biology (BEB) Track

We require students to maintain a 2.0 grade point average (GPA) in the major, excluding allied field courses. See the advising page for information on how to declare your major, who your program advisor is, double majors, double degrees, petitioning for exceptions and more.

To begin the major declaration process for BS in Biological Sciences: Ecology and Evolutionary Biology Track, please .

Major Requirements

Students planning to major in the biological sciences should take BIOL 110L and 111L (or 112L and 113L), and CHEM 131-132 in their first year, and BIOL 198 or 190 and CHEM 203/207 in the fall of their second year.

Introductory Courses (Three Courses)

Select one of the following:

• BIOL 110L: Principles of Biology I
• BIOL 112L: Perspectives in Biology I (pre-requires AP biology exam score of 4 or 5)

Select one of the following:

• BIOL 111L: Principles of Biology II
• BIOL 113L: Perspectives in Biology I (pre-requires AP biology exam score of 4 or 5)
• BIOL 115: Introduction to Organismal Evolutionary Biology (not offered after spring 2017; may use if already taken)

Select one of the following:

• BIOL 190: The Human Genome (highly recommended)
• BIOL 198: Principles of Genetics

Laboratory Experience (Three Courses)

Students are required to take all of the following courses:

• BIOL 225: Laboratory in Ecology and Evolutionary Biology

Advanced Courses: (Four of Five Courses)

Note: majors may take either three advanced electives and one diversification elective, or two advanced electives and two diversification electives.

Both of the following:

• BIOL 205: Evolution
• BIOL 263: Ecology

Plus two or three* advanced electives from the following list (*depending on whether you will take two or one diversification electives):
