Zoology Undergraduate Major (BS, HBS)

Print Version Print
College of Science | School of Life Sciences

Administered by the Department of Integrative Biology under the School of Life Sciences.


Department of Integrative Biology

The Zoology major offers scientific training in the diversity, organismal biology, ecology, and evolution of animals. The major core provides a solid foundation in the biological sciences while electives allow students to cater course work to meet specific interests in animal biology. Zoology majors enter such varied fields as animal care and husbandry, curatorial and museum management, laboratory animal research, field biology and conservation, and environmental management and policy. The Zoology major is not suitable for pre-veterinary medicine students as it does not include the required prerequisite course work (see the option in Pre-Veterinary Medicine in the Biology major).

Students in the Zoology major must complete BI 211 or BI 211H, BI 212 or BI 212H and BI 213 or BI 213H with a C– or better to continue on to upper-division Biology (BI) and Zoology (Z) course work. Students must also complete their General Chemistry series and CH 331 Organic Chemistry with a C– in each term to move on to other Chemistry (CH) course work. Students majoring in Biology, BioHealth Sciences, Fisheries and Wildlife Sciences or Zoology cannot seek a dual or double major in any combination of these four majors. Zoology majors cannot seek the Biology minor.
