Students investigating zoological samples in a lab

The zoology major is a gateway to the diverse areas of modern biology. The major can be tailored to prepare students for advanced study and careers in many different areas: health professions and public health; law; life sciences research in university, government, and industrial settings; education including museum, nature center, secondary school, and college teaching; biotechnology; and environmental studies.

Specialized preparation is offered in ecology, systematics, limnology, morphology, molecular biology, cellular biology, developmental biology, genetics, neurobiology, physiology, evolution, and behavior. Several possible areas, emphasizing different interests, are outlined in the requirements tab. They include ecology, evolution, and behavior; anatomy, physiology, and organismal biology; and cellular, molecular, and developmental biology. The department encourages undergraduate participation in research and offers summer research scholarships to outstanding students.

Goals of the Zoology Major

The zoology major emphasizes critical thinking and conceptual skills that come from an understanding of how scientific information is obtained and evaluated, and of how this information can be applied to societal issues. The major provides a solid foundation in genetic, cellular, physiological, ecological, and evolutionary principles, and in the related disciplines of chemistry, physics, and mathematics. As a result, the major fosters an understanding of biological complexity including the interrelationships among humans and natural systems.

The unique characteristics of the zoology major include:

  • broad-based, yet integrated training in wide-ranging areas of biology;
  • solid foundation of basic principles and processes in biology;
  • flexibility and advising needed to allow students to tailor the major to their specific goals;
  • wide range of opportunities for undergraduate involvement in independent research and senior thesis.

All students who are interested in pursuing the zoology major must schedule an appointment with the Zoology Major advisor. No major declaration forms are required to declare zoology major.

Sample Four-Year Plan

This Sample Four-Year Plan is a tool to assist students and their advisor(s). Students should use it—along with their DARS report, the Degree Planner, and Course Search & Enroll tools—to make their own four-year plan based on their placement scores, credit for transferred courses and approved examinations, and individual interests. As students become involved in athletics, honors, research, student organizations, study abroad, volunteer experiences, and/or work, they might adjust the order of their courses to accommodate these experiences. Students will likely revise their own four-year plan several times during college.

Directed Study

The zoology major is an excellent scaffold for students interested in an undergraduate research experience. A maximum of 10 credits of Directed Studies (ZOOLOGY 299, ZOOLOGY 698, ZOOLOGY 699), Senior Thesis (ZOOLOGY 691, ZOOLOGY 692), or Senior Honors Thesis (ZOOLOGY 681, ZOOLOGY 682) will count toward the 30 credits required for the major.

The Department of Integrative Biology offers both ZOOLOGY 299 Directed Studies in Zoology and ZOOLOGY 699 Directed Studies in Zoology. ZOOLOGY 299 is recommended for students before they have completed their introductory biology course sequence, and ZOOLOGY 699 is recommended for students who have completed their introductory biology course sequence. Directed Studies in Zoology are graded on an A to F scale. Students cannot take Directed Studies on a pass/fail basis.

Directed Studies allows students to gain experience in a wide range of research areas in biology and to learn research techniques that are not easily taught in the classroom. Such experiences allow students to make more informed decisions about their future goals and careers.

Before students can enroll in ZOOLOGY 299 or ZOOLOGY 699, they must set up an appointment with a professor/mentor of their choice, and work with the professor/mentor to:

  1. Decide the specific number of credits, and
  2. Plan the work required to earn those credits.

Such plans can involve reviewing relevant literature in the area, developing a proposal for independent research, and/or conducting an experiment in the mentor's study area.

Students interested in doing in-depth research as undergraduates in an area of interest can elect to do a Senior Thesis or Senior Honors Thesis (see below). Students should contact a department advisor at the beginning of their junior year to explore possible research areas.

Senior Thesis

Students interested in making a longer-term commitment to a research project may consider undertaking a Senior Thesis. Students should contact a department advisor during their junior year to explore possible research areas in zoology.

Zoology Senior Thesis Requirements:

  1. Approval of a department advisor, and
  2. Completion of ZOOLOGY 691 and ZOOLOGY 692, a two-semester thesis research sequence, during the senior year (6 credits).

It is recommended that candidates for the Senior Thesis take ZOOLOGY 699 during second semester junior year to prepare for the thesis.
