Option Physiology and Behavior Undergraduate Option  

   Print Version Print

This option is offered within the following major(s):
Biology - College of Science

The Biology major Physiology and Behavior option is designed to provide a rigorous foundation in the comparative physiology and behavior of animals. Core biological sciences from the Biology major are coupled with course work in behavior, physiology and organismal biology. Undergraduate research or internship experience is strongly recommended for option students, and three credits can be applied to the electives for the option. The Physiology and Behavior option provides excellent preparation for graduate programs in animal behavior, physiology and other areas of organismal biology.

Options in the Biology major require fifteen or fewer additional credits (one term) beyond the basic Biology major, and most students can complete the additional course work in the Physiology and Behavior option in four years. Courses used to satisfy the Physiology and Behavior option requirements also satisfy the Organismal Biology, Physiology, Writing Intensive Course and Upper-division Science Elective requirements for the Biology major.

Students may pursue either the Physiology and Behavior, Pre-Dental, Pre-Medical or Pre-Veterinary Medicine options with the Biology major—no dual combinations are permitted.

It is recommended that Physiology and Behavior option students take COMM 111, *Public Speaking (3), to complete the Biology major Baccalaureate Core communications requirement. Students should also consider taking PSY 202, General Psychology (3), which is optional but required for some of the Psychology elective courses.
