The biology curriculum is designed to provide students an opportunity to study the principles governing life processes within the broader context of the liberal arts. Students investigate the science of life at all levels, from molecular biology to population ecology. Courses are designed to develop each student's ability to acquire and interpret data, pose questions, and critically evaluate facts and theories. By proper selection of biology and other science courses, a student will be prepared for graduate school in the life sciences, for admission to medical, dental, veterinary, and other health profession schools, and for positions in government or industry.

Muhlenberg College provides an opportunity for students to demonstrate disciplinary breadth through completing a minor or second major. The majors in the life sciences (biochemistry, biology, environmental science, and neuroscience) overlap in many of their core requirements and some of their electives. As such, double major and major/minor combinations within the life sciences fail to demonstrate the intended breadth. Students who have a biology major and are interested in adding a second life science major or minor may not double-count electives at 200-level or higher for two majors or a major/minor combination.
