The course begins with a consideration of Darwin's formulation of evolutionary theory and the main influences on Darwin. We will then consider two contemporary persentations of the theory of Richard Dawkins' and Richard Lewontin's. The remainder of the course will deal with a number offoundational issues and may include discussions of adaption, what constitutes a species, whether there is evolutionary progress, and the concept of fitness. We will also discuss the units of selection, the alleged reduction of classical genetics to molecluar genetics, and the possibility of gorunding ethics in evolutionary theory.
