The lecuture meets two times a week from 10:15-11:30 on Tuesday and Thursday (3 credit hours). Lectures materials and activies will be posted at this site if possible, but some materials may only be available through moodle. Discussions will usually try to fall on Thursdays, and will draw from current literature and require active participation. There are a number of required journal articles that should be read for class. They will typically be written beyond the scope of class materials at the time, so you will be expected to be, in part, confused. Perfection is not expected in this class, this is meant to generate questions and discussion. There will also be active computer activities in class which will require submission for points and are graded on participation.

Fall 2026 Schedule

The schedule is still in progress and subject to changes until class begins. The draft schedule and readings are provided below. Please note there are some deadlines for project-related assgnments that do not fall on a class day. This is done to provide some spacing between exams and time for feedback. Slides or activity pages will be made available the day of class.

Grading

Grading will consist of three exams, a class project, and paper discussions. The class project will be a poster on an assigned clade and topic done in small groups. Guidance on poster projects is available on the projects page. The point distribution for the 495 version and dates for project phases are below:

Assignment Points Dates
Exam 1 100 22 September
Exam 2 100 27 October
Exam 3 100 03 December
Project 1 25 25 September
Project 2 25 23 October
Project 3 50 24 November
Project 4 50 01 December
Discussion 1 10 03 September
Discussion 2 10 17 September
Discussion 3 10 22 October
Discussion 4 10 05 November
Discussion 5 10 24 November
Computer Activity 1 10 01 September
Computer Activity 2 10 10 September
Computer Activity 3 10 06 October
Computer Activity 4 10 12 November
Computer Activity 5 10 19 November
Total 500  

Grading is based on the cumulative score and a ten-point scale with +/- grades are used. Here is the point-to-letter distribution for the 495 version:

Percentage (x) Points (x) Letter Grade
x >= 97 x > 485 A+
93 <= x < 97 465 <= x < 485 A
90 <= x < 93 450 <= x < 465 A-
87 <= x < 90 435 <= x < 450 B+
83 <= x < 87 415 <= x < 435 B
80 <= x < 83 400 <= x < 415 B-
77 <= x < 80 385 <= x < 400 C+
73 <= x < 77 365 <= x < 385 C
70 <= x < 73 350 <= x < 365 C-
67 <= x < 70 335 <= x < 350 D+
63 <= x < 67 315 <= x < 335 D
60 <= x < 63 300 <= x < 315 D-
x < 60 x < 300 F

What makes the 595 version different from 495?

Graduate students enrolled in the 595 version of the course will have an additional expectation to write a research proposal in evolutionary biology that builds off of your current research projects or interests. Research proposals should provide a plausible basis for a graduate student or postdoc fellowship proposal, or at least, help develop some background for manuscripts you are working on. 495 students are assigned a plant family of interest for their projects to research and present. The 595 project topics should be proposed by you. The proposal is worth an additional 100 points and has a separate ruberic and template available here. Guidance on research proposal projects is available on the projects page.
