Luca Peliti: Population genetics and evolutionary dynamics


These lectures are an introduction to population genetics and evolutionary dynamics in the language of statistical physics. The analogy between statistical physics and the theory of evolving population was highlightes since the beginning of the evolutionary synthesis. In more recent years, this analogy has been made more cogent by the introduction of concepts arising in the theory of disordered systems. I shall deal with simple models of populations evolving in a fixed environment, with one-parent and two-parent reproduction mechanisms, stressing how it is possible to identify, in the genomic data, the different roles of mutation, selection and chance. The role of evolution experiments in viral and bacterial populations will also be discussed.
