OVERVIEW AND STUDENT RESPONSIBILITIES

This course is an introduction to the study of evolutionary processes. We will examine the basic mechanisms for evolution, including processes that are adaptive and neutral with respect to adaptation. Evolution will be examined at a variety of scales, from molecular to ecological, and from changes in populations over a few generations to patterns over millennia. Along with these topics we will explore the ways that questions about evolution are answered. You will be asked to read and evaluate original literature so that you have direct access to developments in the field of evolution. Your responsibilities include attending class and participating in discussions, checking your e-mail for communications about class, and completing assignments on time. If you do not wish to regularly check your Kenyon e-mail account, it is your responsibility to provide an e-mail address that you will monitor.

Grading in Biology 241 will be based on the following:

Percent

Component

45

Three Hour Tests

20

Weekly assignments. These will be short summaries and critiques of supplemental readings, brief reports on computer simulations, or written responses to discussion questions. The readings or assignments will be provided in class or online. Written work is to be submitted electronically (as an e-mail attachment) by midnight the night before class.

10

Presentation during the last two weeks of class, on a topic of your choosing but which addresses the integration of evolutionary principles into current issues about agriculture, conservation or human health.

10

Attendance and participation in class discussions. More than three unexcused absences will result in point deductions.

15

Final exam (optional). If you choose not to take the final exam, hour tests and weekly assignments will comprise 80% of your grade.

 

 

Policy on Extensions: No extensions will be granted for the assignments listed below on the basis of conflicts with assignments in other classes; look at all your syllabi now and plan ahead for the semester. The only exception is for medical problems serious enough that you are consulting with the College or other professional health services. If an absence is excused, College rules state that you are responsible for the work assigned for that day and class work from that day. Special note about H1N1 flu: If you are experiencing flu symptoms, please follow College guidelines, especially the recommendation to isolate yourself from others until symptoms disappear. You need not have certification from the College Health Service, but please inform me by e-mail of your situation. We will work out a schedule for making up work that is appropriate for your individual situation.

Policy for Students with Disabilities: If you have a disability and feel that you may have need for some type of academic accommodation in order to participate fully in this class, please feel free to discuss your concerns with me in private and also contact Erin Salva, Coordinator of Disability Services at PBX 5453 or via e-mail at salvae@kenyon.edu."
