2026-2028 Catalog

Offered at: San Luis Obispo Campus

The degree offers students a broad education in biology from molecules to ecosystems, with an emphasis on hands-on training in the laboratory and the field. Biology majors can gain pre-professional preparation in the various areas of biology, coursework toward a teaching credential, progress toward professional certification, and/or preparation for graduate training in a field of interest. In addition to the core coursework for the biology major, students may choose a concentration in order to gain a deep, focused understanding of a specific sub-field within biology, or may follow the general curriculum in biology for broader exposure to a variety of topics. Students are encouraged to consult with a faculty advisor and the College of Science and Mathematics Advising Center to help them learn about their chosen degree program, concentration choices, career options, study skills, and departmental opportunities. Students interested in teaching may choose any concentration and should contact the single subject credential advisor for information about teaching opportunities and recommended coursework. Students may not double major in Biological Sciences and Microbiology, or in Marine Science. 

Concentrations

Anatomy and Physiology

Offered at: San Luis Obispo Campus

Students in this concentration study biological sciences with an emphasis on the structure and function of humans and other animals.  This concentration is ideal for students preparing for careers in the health professions. 

Ecology, Evolution, Biodiversity, and Conservation

Offered at: San Luis Obispo Campus

This concentration will prepare students to study the ecology and evolution of the earth's biodiversity and to participate in its conservation. The concentration will provide students with the skills necessary to participate in the conservation of wildlife, plants, and other wild species and their habitats. Professions in this arena include basic and applied research with state and federal resource management agencies, non-governmental organizations (N.G.O.s), and private consulting firms. These professions require a solid foundation in the identification of organisms, the principles of ecology and evolution, and the tools, policies and social context of conservation. This area of concentration is recommended for students seeking professional certification by off-campus entities such as The Wildlife Society and the Ecological Society of America; students interested in such certification programs should consult with their faculty advisor for specific programmatic guidance. 

Molecular and Cellular Biology

Offered at: San Luis Obispo Campus

Designed for students who are interested in how genes and their products work to create and maintain cells, tissues and organisms.  This concentration augments the diverse biological sciences curriculum with courses in molecular and cellular biology, and electives such as biochemistry, bioinformatics, cellular immunotherapy, immunology, developmental biology and virology. This concentration is ideal for students interested in biotechnology or biomedical research, and is also an excellent option for students planning future studies in the health professions. 

General Curriculum

Offered at: San Luis Obispo Campus

The General Curriculum provides the greatest flexibility allowing students to take coursework across all areas of biology. This breadth of knowledge across the biological sciences may be especially beneficial for students considering teaching biology at the secondary level. Students who do not declare a concentration will default to the General Curriculum. The General Curriculum in Biology is not a concentration but can be used to fulfill the unit requirements of a concentration. 

Program Learning Objectives

  1. Explain fundamental concepts of biology in the following areas: diversity & evolution; structure and function at multiple hierarchical levels; information flow; energy and matter transformations; interactions among and between organisms and the environment.
  2. Demonstrate proficiency in the appropriate lab and field techniques in their area of specialization in biology.
  3. Locate and critically evaluate the scientific literature.
  4. Apply the process of science to design, conduct, analyze and interpret experiments in biology.
  5. Integrate statistics, math, physical sciences and technology to answer biological questions.
  6. Communicate biological principles and research findings effectively to diverse audiences.
  7. Relate ethical, social justice or global perspectives to the study and practice of biology.
