The Ecology, Evolution, and Behavior option provides students with an education in ecological studies and biodiversity, and also emphasizes field experience. The degree requires courses in genetics, ecology and evolution, as well as at least one advanced course in cellular or molecular biology, physiology/behavior and biodiversity. Students have the option of tailoring their course and lab requirements in some of these areas to emphasize animal, plant, or ecological studies. Graduates may take positions with government agencies, enter consulting firms, or continue with graduate studies for an academic career at colleges, universities, museums, or other research organizations.

Declare This Major

Current UT undergraduates interested in changing to the Ecology, Evolution, and Behavior major should complete the following instructions:

  1. Complete the entry-level courses (Calculus 1, CH301/302, and BIO311C/D) with at least a C- or higher
  2. View the online information session.
  3. Complete the questionnaire at the end of the session and bring it your advising appointment.
  4. Schedule an appointment with the Biology Advising Center.

Current undergraduates who have not yet completed the entry-level requirements should schedule an appointment with an academic advisor in WCH 1.106. Contact the appropriate College of Natural Sciences Advising Center to schedule an appointment and change majors to Biological Sciences.

Prospective University of Texas at Austin students should visit to learn about the application process and how to declare a major.
