Next Tuesday we’ll start by reviewing what we’ve learned about genetic drift so far. Please come prepared to ask any questions you have about the basic process, effective population size, or the interaction of drift with mutation, migration, or selection. We’ll revisit some of the results we’ve already seen, but through a different lens. We’ll be looking backwards to develop the conceptual tools we need to make inferences about population history from the data we collect rather than looking forwards as we’ve done so far in the course. The lecture detail page includes a link to an HTML page and the corresponding R markdown file. There’s no need to play with the R markdown before lecture, but if you have a chance to download it, you might want to use it to follow along in lecture on Tuesday.
