I am available at other times please email me at [email protected] for an appointment. I am not usually available before 10:30 am and all day Fri. Your contact information: I may need to contact you during the semester. Please go on Blackboard and change your email address to the one you use most frequently. Make sure that the junk mail is cleaned out. Text is Freeman and Herron, Evolutionary Analysis, 4th Ed., Pearson, ISBN 0-13-227584-8. This text is available at the College Bookstore and online at a discount from Amazon.com, barnesandnoble.com and ebay. To find the cheapest price, copy the ISBN number into Google and vendors will pop up. The papers we are going to read are posted on Blackboard Grades: There will be 3 exams, including the Final, which is given during Finals week. The exams are NOT cumulative. I do not give make-up exams except in cases of documented illness. If you have a conflict with a scheduled exam, I will allow you to take it early. Please see me as soon as you know you’ve got a problem. For undergraduates, these exams will comprise 80% of the grades in the course. An additional 20% of your grade will be based on discussions of papers in the primary literature that I will assign every week. For MA students, the exams will comprise 60% of your grade, 20% will be from the paper discussions and 20% will be based on a term paper, which you will hand in at the end of the semester. Attendance: Attendance in this course is mandatory. Any student who misses more than 2 lectures will be dropped from the course with a grade of WU. Students with Disabilities: Accommodations will be made for students with documented learning disabilities. Please see me for details before exams. Description: Evolution is the central, unifying theory of biological science. A shared evolutionary history can explain similarities among species in development, behavior, morphology, and Evolution Spring 2012 2 physiology. Evolution continues today, explaining such phenomena as the development of new human diseases and the increases in pesticide and antibiotic resistance. The approach taken in this course is to examine recent research in Evolutionary Biology at both the morphological and molecular levels. A major objective is to get students to think critically about experimental design in the primary scientific literature. Goals and Objectives: 1. To examine basic principles of evolutionary biology 2. To learn methods of modern evolutionary research 3. To integrate the fields of molecular biology, genetics, ecology and physiology with evolution. This course can be regarded as a capstone course in the Biology major. 4. Critical thinking about experimental design is a central theme of this course. Students will be expected to read and criticize primary literature that involves evolutionary principles.

One student will present the background and the methods, the other one will present the results and discussion. Both students will answer questions. The presentation should last a Evolution Spring 2012 4 total of 20 minutes. I do NOT want you to read the paper to us. I want summaries and criticisms. The most difficult thing for students to do is to put primary research in context in order to judge its importance. This context comes from additional readings. Start with reading the text’s treatment of the topic. Then scan the abstracts of the papers cited in the Introduction of the paper you are presenting. The librarian can help you find references online. The papers are scheduled to be more or less coincident with the relevant topic in lectures. Term paper (MA students only): I want you to select a topic in evolution that is relevant to your career goals. You must review the literature critically on this topic and explain what the next relevant experiment should be. The paper should be no more than 5 single spaced (or 10 double spaced) typed pages plus one page of references. Your topic must be cleared with me by 2/28/2011. I want an outline of your paper and 5 references by 4/4/11.
