Ecology, Evolution and Behavior Option Degree Requirements

The Bachelor’s degree in Biological Sciences with an Ecology, Evolution and Behavior option requires 34 credits that include Bio Sci 150, Bio Sci 152, and 26 credits in courses at or above the 300 level. Required and elective courses for this option are listed below. Additional requirements include courses in natural sciences, humanities, formal reasoning, international awareness, and research. As a Letters & Sciences student, you must also meet foreign language competencies (which may be satisfied if enough coursework was taken during high school).

It is important to understand your Letters & Science Degree Requirements because they will differ depending on whether you choose to obtain a Bachelor of Science (BS) or a Bachelor of Arts (BA) degree.

Because there are many pathways to the degree depending on your particular circumstances, it is very important to meet with your Letters & Science and your Biological Sciences advisors at least once a semester to make sure you are on-track. Some classes may count towards more than one requirement and with early planning, you can save yourself time and money.

Our four-year plan shows one possible route to completing a BS degree with a flexible biological sciences major in four years.

Since most students choose the Bachelor of Science path, below are the requirements to earn the biological sciences major, flexible option.

Students may not combine Bio Sci 150, 202, and 203 for more than 9 credits toward the major.

Students must complete at least four (4) laboratory courses.


Students in biological sciences who meet all of the following criteria are awarded honors in the major upon graduation:

3.500 cumulative GPA in all UWM graded credits attempted;

3.750 GPA in UWM courses counting toward the major;

3.500 GPA in all advanced credits that count toward the major; and Complete a laboratory or field research independent study (Bio Sci 697, 698, or 699) or internship (Bio Sci 489 or CES 489).

Students who believe they may qualify for honors in Biological Sciences should apply to the Department during their last semester of study.


Students who plan to attend graduate school are advised strongly to take the one-year sequence of Organic Chemistry with lab, and two semesters of Calculus


Students must attain a GPA of 2.000 in all Biological Sciences courses, including any transfer work.
