Course description
Evolutionary Biology is designed primarily for advanced biology majors. As such, the material will explore both the fundamental concepts in evolution and how evolutionary biology is conducted (experimental design, data analysis). The course is primarily lecture-based, meant to help you summarize the information from the textbook and to practice applying concepts via homeworks and exams. We also will read a combination of journal articles and popular works about evolution to illustrate points covered in lecture and to familiarize us all with the latest in the field. Discussions during the last portion of the semester will be student-led, with a pair of students presenting information to the class. We will examine how different organisms have solved environmental challenges through evolutionary adaptation. The ultimate goal of this course is to help you develop an appreciation for, broad exposure to, knowledge of and continuing interest in organismal biology.
Course Goals
Gain a rigorous knowledge of the principles of evolutionary biology, specifically:- Understand current thinking on evolutionary forces and effects
- Understand how and why evolution interrelates much of biological disciplines
- Design experiments to test evolutionary theory
- Gain understanding and confidence working with mathematical models in biology
- Learn how to synthesize and present a biology topic
- Learn detailed information about systems & organisms that you have never heard of
- Actively apply critical thinking to oral discussions and in writing
- Actively participate in discussions and help mould the course structure when necessary
Course Assessment
There are 280 points in the course, made up of the following:
Lecture Exams (4 x 50 pts. = 200 pts): Exams will cover material highlighted in lecture and detailed in the accompanying textbook readings for that section. I expect you not only to recall what you’ve studied but to also be able to synthesize and apply ideas. Exams will not require calculators, but you are expected to know and understand the use of formulas/models discussed in lecture.
Discussions (6pt outline + 4pt questions): To enhance our discussion, we will have two consecutive “journal clubs” for each paper. You will be assigned to attend only one of these. There are two discussions in which you will have an assignment. The Outliner writes a 1-2 page outline of each reading for discussion that day (there may be more than one paper); a total of four copies are turned in at the start of class on discussion day. This activity is worth 6 points. The Questioner writes two exam-style questions that cover the readings and supporting textbook pages. The questions are posted on Moodle at least two hours before class on the day of the discussion. Each question is worth 2 points. The remaining students do not have an assigned duty, but are expected to discuss.
Oral Presentation (5pt outline + 20pt talk = 25 pts.): Students will form teams of two persons and present a topic in evolutionary biology (12 min talk, 4 min questions). Presentations ideally mix the background material present in your textbook + a particular experiment you think is cool + your thoughts and impressions. The topic must synthesize one to three peer-reviewed papers published after 2003. Presentations are evaluated for (in order of importance): thoroughness, conciseness and professionalism. Thus, even if you are dead afraid of public speaking, your background research and writing skills can still earn you a fine grade on the assignment.
An outline of the talk, with literature cited, is due one week prior to the presentation. Students will randomly draw the order in which they will choose the date and time of their presentation.
Problem Sets (2 x 15 pts. = 30 pts): Evolution is a very quantitative science, and as such we will apply our lecture concepts and formulae to data. Problem sets can NOT be turned in late. Showing your work is not required, but is essential for partial credit if you miss something.
