Put another way, there is a theme of understanding the biodiversity of form from various points of view.
Topics range from experimental or developmental biology to the evolution of animal diversity.
Studies in vertebrate morphology also span from molecular to community levels of organization. They include biomechanics, the application of mechanical principles to the structure of organization. Most people start with an interest in animals and animal watching as kids. Later, many become interested in comparative anatomy in college. It provides the potential to understand mechanisms that are responsible for much of vertebrate diversity.
