The College of Natural and Agricultural Sciences (CNAS) provides both Bachelor of Arts and Bachelor of Science programs in Biology. These degree paths share a foundational philosophy that comprehensive undergraduate education in biological and physical sciences, complemented by humanities and social sciences, forms the essential groundwork for aspiring biologists. The key distinction lies in the B.A. requiring 16 units of foreign language study, while the B.S. mandates an additional 16 units of advanced coursework in biology or related disciplines.
Departmental research and instruction span all tiers of biological organization - from cellular and developmental processes to physiological, organismal, ecological, and population-level studies. Foundational courses (BIOL 005A, BIOL05LA, BIOL 005B, and BIOL 005C) introduce these organizational levels while highlighting biology's unifying principles.
Given biology's vast scope and diverse career pathways, students enjoy significant flexibility when choosing upper-division courses to fulfill the 36-unit major requirement. Typically, most upper-division units come from Biology Department offerings, though with advisor approval, relevant courses from departments like Biochemistry or Cell Biology and Neuroscience may also count toward this requirement.
