Biology is a broad area of science that includes the study of every aspect of living systems, their interrelationships and interdependencies. One of its purposes is to help people to understand themselves and their role in the biosphere. Most courses are designed with the thought that students should be stimulated to carry out critical, independent work. Students majoring in Biology are prepared for a wide variety of professional, cultural, and vocational opportunities including graduate study, the medically allied professions, and teaching (see descriptions of specific programs). Expanded programs of research will also absorb greater numbers of welltrained biologists. Present day biology makes liberal use of chemistry, mathematics and physics as tools. A student planning a career in biological science must therefore acquire a sound background in these basic fields.
