This major is broad in concept, designed to span the numerous core disciplines of biology. The Biological Sciences major covers most dimensions of the study of life, ranging from the molecular to the population level. While emphasizing breadth, the Biological Sciences major also has an area-of-emphasis requirement that provides concentrated attention to one facet of biology at the upper division level. Each area of emphasis coincides with one of the sections of the division.

Major:

The major in evolution and ecology offers the student a broad background in the theoretical and empirical basis of our understanding of evolution and ecology of living organisms. The program of study begins with a core of introductory courses in mathematics, physical sciences, and biology. These are followed by survey courses in evolution and ecology and more specialized courses that allow the student to focus his or her studies.

Major:

Microbiology deals with bacteria, yeasts and other fungi, algae, protozoa, and viruses. These microorganisms are ubiquitous in nature and play a crucial role in areas such as agriculture, biotechnology, ecology, medicine, and veterinary science. The field of microbiology contributes to areas of fundamental inquiry such as biochemistry, cell biology, evolution, genetics, molecular biology, pathogenesis, and physiology.

Major:

The Section of Molecular and Cellular Biology offers two majors. The biochemistry major introduces students to the chemistry of living organisms and the experimental techniques that are used to probe the structures and functions of biologically important molecules. Students who enjoy both chemistry and biology and who are comfortable with quantitative approaches to problem solving will find biochemistry a rewarding field of study.

The genetics major provides a broad background in the biological, mathematical, and physical sciences basic to the study of heredity and evolution. The major is sufficiently flexible to accommodate students interested in the subject either as a basic discipline in the biological sciences or in terms of its applied aspects such as biotechnology, medicine, and agriculture.

Majors:

The study of physiology is concerned with understanding the mechanisms that control and carry out the vital functions of living organisms. From the single cell and its parts, through the various organ systems, to the whole animal and its relationship to its environment--the entire range of function of living matter is investigated.
