The program focuses on the history, development, and interaction of living organisms on this planet. Majors study species evolution, the effect of environmental pressures on evolution, patterns of biological diversity, and species interaction within a given ecosystem. Degree programs within the department offer different levels of concentration. The BS prepares students for graduate study in the field and offers course work in population, community and physiological ecology, behavior, population theory, biogeography, natural history, genetics, systematics, morphology, and evolution. The BA is for students interested in natural history and the biological sciences who do not wish to continue with graduate study.

AZ Transfer Pathways

This page is designed for in-state transfer students who plan to attend the University of Arizona. The information presented lists the most accurate course equivalencies and may not include all possible requirements. Transfer students are strongly encouraged to use this site for reference only and not for self-advising.

Transfer students should work with their community colleges and UA advisors to develop an individualized plan for transfer, and visit

  • All posted Pathways (except for Bachelor of Applied Science Pathways) fulfill an AGEC and most also fulfill an Associate Degree
  • Following a Pathway does not guarantee admission to the UA nor admission to a college/major/program at the UA
  • Use Pathways in consultation with advisors from your community college and the UA
  • Pathways are subject to change at any time
