Selection and genetic drift

I got to looking at the syllabus over the weekend and realized that I didn't have a lecture scheduled on the interaction between drift and selection. Since understanding that interaction is crucial for understanding a lot of evolutionary processes within populations, we need to spend a little time on it. So as interesting as it would have been to spend more time talking about migration and population structure, I've decided to drop that.

We'll probably spend some time finishing up selection and drift on Wednesday before we start talking about the coalescent.
