Transcript: Robert Sapolsky on Behavioral Evolution II at Stanford

Sharing is Kindness in Action!

Robert Sapolsky

Stanford professor Robert Sapolsky discusses Behavioral Evolution II in detail at Stanford. In this evolution lecture, he focuses on individual and kin selection, behavioral logic, competitive infanticide, male/female animal hierarchies, sex-ratio fluctuation, intersexual competition, imprinted genes, sperm competition, inbred-founder populations, group and multi-level selection, and punctuated equilibrium. This lecture presentation occurred on April 2, 2010.

Let’s get going. Various announcements, procedural things. A number of people want more information about grading and what the exams are like, all of that. I think I mentioned one-third of the points will come from the midterm, two-thirds from the final. In terms of the style of the midterm, the midterm is heavily going to be about making sure you got down all the factoids from the first half of the course, that you’ve got the basics of each of our proverbial buckets. The second half of the final is all going to be about integration, thinking across the different categories. So just a sense of that.

Readings. Readings, as they are coming out, the books are not required until the second half of the course. The handout on Monday, I think, said which chapters of the Zebra book you should read. We will shortly get to you which chapters of the Chaos book you should read as well. The readings that are being posted on the CourseWorks, the downloads of various published papers, those are required. I’m clear on those whether this is a paper you should read all of, if this is one you should read the abstract of. Even if you read all of, do not read it in some obsessive, detail-oriented way. The goal is probably to be able to say, in one or two paragraphs, why this paper has something pertinent to say about the topic they fell into. You’re not sitting there having to memorize techniques, middle names of the authors, how many animals, anything like that.

In terms of that, it probably makes sense to read those after the first lecture of whatever block there is. And hopefully, if I get organized, I’ll be able to get you sort of a list of the readings further in advance than one week in advance. Nonetheless, you should probably hold off reading it until after the lecture occurs.

Let’s see. What else? People wanted to get a sense of how long things were going to go. And as we’ll see today, the evolution lecture topic will cover two classes. Molecular genetics, which is what we’ll pick up on Monday, I’m guessing one to one and a half. Behavior genetics following that, one to one and a half, ethology one. Neurobiology, endocrinology, we’ll have one week devoted to intro to the topics. And again, that’s one where this is so important for everybody to be up to speed rather than these being in catch-up sections that week. The whole week, Monday, Wednesday, Friday, will be devoted to that with the TAs teaching it. The following week, three more lectures, more advanced ones. And depending on proximity to the midterm, there may be a half-lecture in there on statistics, or maybe not. So this is going to depend on keeping on schedule. This is a rough approximation. The midterm is going to be a Monday night. You will be responsible for material up to the previous Wednesday, and there will be lots of review stuff. Take a look at the extended notes being posted.
