Investigates how specific physiological functions and animal behavior have underlying biochemical, cellular and organ system structural designs. Focuses on comparative physiology in the context of how animal systems can be influenced by environmental conditions and how these have been modified through evolution. Includes small group projects in which students independently design, implement, analyze and present semester-long research projects in the form of a simulated symposium. Three hours lecture and three hours laboratory. Prerequisite: BIO-341 Vertebrate Anatomy and CHM-211, each with a minimum grade of C or permission of instructor. [4 credits]
