Preparation for Careers in Biology
The Biology programs are designed to equip students for their desired career paths. The Bachelor of Arts degree offers students the opportunity to blend their study of Biology with additional studies in other sciences such as Chemistry or Geosciences. The Bachelor of Science degree for Teaching Credential Candidates prepares students seeking a science education career in grades K-12 or in adult school. The Bachelor of Science and the Bachelor of Science with Honors degrees offer students the highest level of Biology preparation.
In each program, students select the Biology electives that interest them most and prepare them for their future careers in health care (e.g., dentistry, medicine, pharmacy, nursing and physical therapy), research (e.g., biotechnology, microbiology, and vector biology), wildlife biology (e.g., ecology, biodiversity and conservation) or higher academics (earning a Master’s or Doctorate degree to teach at the community college or university level). Along each path, students are exposed to the major areas of the biological sciences so they can discover and develop the subject areas that stir their passion as they prepare for post-baccalaureate study or employment.
Preparation for admission to the undergraduate program should include high school work in algebra, geometry, trigonometry, biology, chemistry, and physics.
Experiential Learning Opportunities
Many students participate in undergraduate research (BIOL 197). Over a period of one or more semesters, these students interact closely with faculty on research projects and get hands-on experience with modern research instruments. Stipends are available to selected undergraduates for summer research. Awardees are given the title of Fred and Marguerite Early Undergraduate Research Fellow. Students also are encouraged to participate in Co-op/Internship experiences at dental offices, medical clinics, industries, Micke Grove Zoo and other work areas.

How do butterfly wings get their spots and stripes? Why do dolphins and humans have the same bones in their limbs? How did Darwin’s finches quickly evolve so many different beak shapes? These are all questions that require an understanding of Evolutionary Developmental Biology (EvoDevo) to answer. EvoDevo explores the intersection of Evolution, Developmental Biology, and Genetics. This course covers introductory topics in those three fields, theoretical underpinnings of EvoDevo, as well as case studies. This course uses phylogenetic and developmental genetics frameworks to examine topics that include body-plans and patterning, genetic and morphological complexity, and novel features. Prerequisites: BIOL 51 and BIOL 61 or permission of instructor.

The structure and dynamics of populations, biotic communities and ecosystems, is emphasized with particular focus upon relationships of organisms to their environments. Prerequisites: BIOL 051 and BIOL 061.
BIOL 176. Ecology and Conservation Biology. 4 Units.
The principles of ecology are introduced with attention to consider threats and disruptions to ecological systems from the level of local populations through ecosystems, landscapes, and global processes. Ecological principles are used to help understand these systems, to make predictions for the future or for other systems, and to evaluate possible solutions. The class considers the importance of economic and demographic forces in causing conservation problems and in shaping conservation strategies, and students practice planning conservation areas. Prerequisite: BIOL 051.
BIOL 177. Natural Medicines. 4 Units.
A lab course that surveys drugs found in nature, in particular their history, uses, and mode of action, and is designed as a preparation for students who will attend a Pharmacy or Dental School. Topics include history of medicine, survey of natural compounds relevant to pharmacology, and survey of naturally-derived drugs used to treat cancer, heart disease, and neurological disorders. Prerequisites: BIOL 051, BIOL 061, BIOL 101, CHEM 123 with a "C-" or higher.

Lectures and readings on the mechanisms of evolutionary change in organisms are the focus. Prerequisites: BIOL 051 and BIOL 061. Recommended: BIOL 101.
BIOL 180. Human Physiology. 5 Units.
This course is a lecture- and laboratory-based review of the functions of the major organ systems of vertebrates with emphasis on the human body. Lab exercises demonstrate basic physiological processes in the human body and emphasize techniques of instrumental data acquisition and data presentation. Credit will not be given if a student has taken BIOL 111. Prerequisites: BIOL 061 and (CHEM 023 or CHEM 024 or CHEM 025 or CHEM 027). Recommended: one semester of genetics.
