  • Bachelor of Science in Biological Sciences, Concentrations in:
    • Molecular and Cellular Biology
    • Ecology
    • Physiology
    • General Biology
  • Minor in Biological Sciences


Biology is the study of living processes from the interaction of species with each other and their environment to the operant molecular mechanisms. The California State University San Marcos Biological Sciences Department presents a broad program of courses that deal with life on the ecosystem, population, organismal, and molecular levels. One common principle that extends throughout our curriculum is that biological processes should ultimately be biochemically explainable and mathematically describable. Life is a complicated series of chemical reactions and interactions, and we seek to understand the relationship of organisms to each other, to their environment, and within themselves in biochemical terms.

Biological Sciences majors may choose between:

  1. a general concentration,
  2. a molecular and cellular biology concentration,
  3. an ecology concentration, and
  4. a physiology concentration.

The general concentration provides wide exposure to the range of biological sciences while the cell/molecular, ecology, and physiology concentrations offer majors the opportunity to focus their studies. With appropriate choice of biological sciences electives and General Education electives, graduates can meet the requirements of admission to graduate, medical, dental, optometry, veterinary, and other professional schools.
