Biology is the scientific study of life. At no time in history has biology been more visible and important to human life and the future of our planet. Today the biological sciences are experiencing a revolution. Within the Faculty of Arts & Science there is no single biology department. Biology courses are taught by members of the departments of Cell and Systems Biology and Ecology and Evolutionary Biology. Students who wish to focus on either plant and microbial biology or animal biology can take courses within the Biology programs that concentrate in these subject areas. The diverse course offerings within the Biology programs allow students to customize their educational experience to match their personal interests.
