Requirements for the Major in Biology 

A four-year program leading to a B.S. in biology is offered and includes 4 options: Biology, Human Biology, Biotechnology, and Ecology. All programs of study provide students with a liberal arts education emphasizing the sciences. The required biology courses in the Biology specialization expose students to an examination of life from the molecular to the community level. The required courses in the Ecology specialization prepare students for careers in ecology, environmental sciences, and conservation. The required courses in Human Biology prepare students for the health professions. The required courses in the Biotechnology specialization emphasize cell and molecular biology. Other biology courses may be elected to suit individual interests and needs. The required courses in chemistry, mathematics, and physics reflect the interdisciplinary status of the biological sciences. Graduates of these programs have found careers in biological and medical research laboratories, field biology, and in biotechnology companies, or they have furthered their education by entering graduate, medical, dental, optometry, veterinary, and law schools, as well as schools for allied health professions.

Please see the suggested four-year plans of study and the 2008-2010 tentative course schedule to facilitate the planning of your classwork.
