Course Logistics

This twenty-weeks long course is designed to introduce students of Biosciences to the exciting world of diversity of living organisms: numerical approaches to quantify the staggering biodiversity and interrelationship of organisms in the light of evolutionary thought: Biosystematics.

Lectures
PowerPoint slides of lectures will be available here. The lectures build on each other, so you should view them in the order listed. The few lectures listed as "Honors" or "Optional" will not be covered on the quizzes but are provided in case you want to go into more depth.

Reading
Course textbook is Plant Systematics by Judd et al. Amazon Link

Exercises

Short ungraded exercises will occasionally be embedded into lectures. Each lecture will be followed by ungraded exercises. Answers to these exercises will be given and explained after you reply to the questions. These exercises do not introduce new material, but they enable you to check your understanding of the lectures. If you miss too many of the exercises after a lecture, then you might want to listen to that lecture again.

Time Commitment

You should expect to spend on about 2 hours per week watching the lectures, another 2 hours per week doing the exercises, and about 1 hour on each quiz. You might want to spend additional time doing the reading and participating in the discussion forums.
