Students should come to Comparative Anatomy prepared by one or more substantial courses in Zoology, and should be in their upper college years. They can then use the course effectively to equip them for medical school, for advanced study in zoology, or for teaching. Yet Comparative Anatomy is much more than a professional training course. Its understanding of man's origin and relationships; it is at the heart of our knowledge of evolution. By acquainting us with the changing structure of a great host of animals, the study of Comparative Anatomy gives a framework in which we can properly place our ideas of function and of embryonic development.
