I’ve posted the notes on genetic drift. We’ll be covering a lot of pretty complicated stuff this week. I encourage you to take a look at the notes beforehand. There’s a good chance that many parts of them won’t make a lot of sense, but if you’ve reviewed them before we get to lecture, you’ll be in a better position to ask questions in class.
I also have to apologize for Thursday’s lecture. The video is now linked from the lecture detail page, but I forgot to turn the microphone on. As a result, you see all of the slides, but there isn’t any audio. I deeply regret the error. I’ll do my best not to repeat it in the future.
