To give you an outline of what we're going to discuss today first I'll introduce genetic drift as the concept and define it. And then I'll talk about how in population genetics we might model genetic drift both through theory and also some illustrative simulations that will illustrate some theoretical principles. Then I'll discuss the signature of genetic drift on human population genetic data, so patterns that have been identified, mostly within the last decade, from studies directly done on humans living today. And I'll end by talking about how important genetic drift is and especially some future directions for studying the role of genetic drift in human populations. So first let's begin with introducing the concept of genetic drift.
