DEWITT The Department of Zoology offers graduate work leading to the degrees of Master of Science in Teaching, Master of Science, and Doctor of Philosophy. The work of the department is divided into two general areas: comparative biology of the whole organism, and studies at the cellular and molecular level of organization. All candidates for graduate degrees will be required to take the following: introductory biology or zoology, ecology, embryology, compara- tive anatomy or functional morphology, invertebrate or vertebrate zoology, genetics, cellular physiology, one year of physics, chemistry through organic, and a sequence in mathematics or statistics. The remainder of the student's program will be determined by his supervisory committee. Undergraduate preparation in zoology: Prospective graduate students should take as undergraduates as many as possible of the courses listed in the pre- ceding paragraph. These courses constitute a core curriculum for all candidates for the M.S.T., M.S., and Ph.D. degrees. Any of the courses not taken as an undergraduate must be made up early in the graduate program and without graduate credit. Entrance requirements: The minimum requirements for admission to the graduate program in zoology include an average of 500 or better on the Verbal and Quantitative portions of the Graduate Record Examination and a major in zoology plus a total of 30 credits in chemistry, physics, and mathe- matics, or a major in chemistry, physics, or mathematics plus 21 credits in zoology. Students with special training or aptitudes may be allowed some variation in prerequisites. Examinations: All graduate students will be given a written examination covering the zoological portion of the core program by the Departmental Examining Committee early in their first term of residence. The results of this examination will be used in planning the student's program. It will be the responsibility of the candidate's supervisory committee to take whatever action is necessary to insure that the nonzoological portion of the core program is satisfactorily completed.
