Students begin the Biology major with Foundations of Biology (BIOL 101), Intermediate Cell Biology and Genetics (BIOL 201) and Evolution in Action (BIOL 202). Foundations of Biology gives an overview of the fundamental themes of biology within the context of a specific biological system, which varies from section to section. Intermediate Cell Biology and Genetics course builds on the material covered in BIOL 101, and includes biological molecules, cell structure, cell signaling, metabolism, and classical and molecular genetics. Evolution in Action is an examination of evolutionary processes in the context the of important biological themes of information transfer, the exchanges of energy and materials, reproduction and the transmission of genetic information, and the dynamics of biological populations and communities. BIOL 101 and 201 are meant to be taken in the first year, while BIOL 202 should be taken during the sophomore year, as it is a prerequisite for many upper-division courses. Entering students may be eligible for credit on the basis of the Advanced Placement test in Biology, the International Baccalaureate or the College Level Examination Program (CLEP).
