An introduction to the evolution, ecology, and behavior of organisms and how these relate to the diversity of life. Following a discussion of the core components of evolutionary theory, we'll examine how evolutionary processes have shaped morphological, anatomical, physiological, and behavioral adaptations in organisms that solve many of life's problems, ranging from how to find or acquire food and avoid being eaten, to how to attract and locate mates, and how to optimize reproduction throughout a lifetime.

Perhaps no subject in biology is as troublesome (or as fraught with contradictions) as sex. Why should organisms devote so much of their time and energy to attracting mates, when they can reproduce much more efficiently by cloning themselves? Similarly, why not pass on all your genes, rather than just half? Darwin was among the first to realize that competition for mates is sometimes as important as competition for survival. Sex is an exceedingly powerful ecological and evolutionary force, responsible for generating a tremendous diversity of morphologies and behaviors.

Fall and spring semesters.

(Offered as PHYS 400, BIOL 400, BCBP 400, and CHEM 400.) How do the physical laws that dominate our lives change at the small length and energy scales of individual molecules? What design principles break down at the sub-cellular level and what new chemistry and physics becomes important? We will answer these questions by looking at bio-molecules, cellular substructures, and control mechanisms that work effectively in the microscopic world. How can we understand both the static and dynamic shape of proteins using the laws of thermodynamics and kinetics?

(Offered as BIOL 331, BCBP 331, and CHEM 331.) Structure and function of biologically important molecules and their role(s) in life processes. Protein conformation, enzymatic mechanisms and selected metabolic pathways will be analyzed. Additional topics may include: nucleic acid conformation, DNA/protein interactions, signal transduction and transport phenomena. Four classroom hours and four hours of laboratory work per week. Offered jointly by the Departments of Biology and Chemistry. A student may not receive credit for both BCBP/BIOL/CHEM 331 and CHEM 330.
