General Course Objectives

 

One doesn’t have to be a scientist to want answers to profound questions.  Who are we?  Where did we, and all of the rest of the astounding diversity of life, come from?  How did life first arise?  Why is the living world put together in the way that it is?  Does the apparent history of the living world make sense in any way?  The main purpose of this course is to introduce you to answers that scientists—biologists, paleontologists, ecologists, biochemists, geologists, and many others—have developed in answer to these questions, and to teach you the strategy that they have used to fashion these answers.  In the process, you no doubt will fashion answers of your own to these and many other questions, and sharpen your intellectual skills for addressing a broad variety of other questions.  Learning about evolutionary theory and the history of life will require you to think like a scientist.  You will learn about the nature and limits of science, how science differs from non-science and “pseudo-science”, come to understand a world-view that explains the origin and nature of biological reality, and hone your ability to think critically about and evaluate new ideas.

 

Course Materials

 

Rose, M.R., and L.D. Mueller. 2006. Evolution and the ecology of the organism.  Pearson/Prentice Hall, New Jersey

 

There will be additional readings throughout the semester from other sources.  These materials either will be provided to you or placed on ereserve in the library.

 

General Course Plan

 

This course is designed differently from many others that you already may have taken.  You will be asked to think critically about subject matter throughout the semester, and all of our class activities will be designed to help you think more clearly as a scientist, and to reflect your growing familiarity with evolutionary theory and the understanding of the world that such an understanding provides.  You will learn some of the “facts” of Biology and about evolution, in particular, but by and large, our time will be focused upon coming to an understanding of the idea of evolution and evaluating the evidence marshaled in its support.

 

You will be asked to do reading for every class period, and you will be expected to bring a completed assignment to every class period.  You will be expected to actively participate in every class period, by discussing readings, offering a point of view or explanation, citing examples, restating arguments, and so on.  You frequently will be involved in group work in class, self-assessment, and peer assessment.  My goal is that you become an active and critical learner, constantly assessing what you say and hear, and that you sharpen your thinking ability in many ways.

 

General Course Topic Structure

 

  1. The Nature of Science

How does science work? What kinds of questions can science answer?  Which can it not address? What are scientific facts?  What do scientists mean by “hypothesis” and “theory”?

  1. An Introduction to Darwin and to Darwinism

Who was Charles Darwin?  What was the state of thinking about questions of origins and about evolution prior to and at the time of Darwin?  How did Darwin come to study evolution?  How did Darwin act as a scientist?  How does evolutionary theory qualify as ‘good’ science?

  1. Modern Confirmation of Darwinism

Why were the developments of genetics and population genetics important to constructing support for Darwin’s theory?  How did discoveries in Molecular Biology, such as the discoveries of the structure of the genetic material and the way that it becomes expressed amplify our understanding of evolutionary theory?  Has evidence been developed to answer the questions that Darwin himself raised as possible objections?

  1. The Elements of Darwinian Theory

What did Darwin mean by a “struggle for existence”?  What is natural selection and how does it operate in nature?  What sorts of evidence, both experimental and observational, did Darwin offer in support of his theorizing? 

5.       Nature plays out the results

Coevolution – How do predators and prey, hosts and parasites, communities, and other groups of multiple players become organized structurally and functionally as a consequence of the evolutionary process?

6.       Evolution and societies

Why did sex evolve?  How has evolution affected mating strategies?  How are social behaviors adaptive solutions to common problems?  What elements of human behavior are driven by evolutionary forces?

Daily assignments – You will have an assigned reading and assignment in advance of each class period.  You will be asked to provide reading notes, may be asked to respond in writing to one or more questions about this reading, interpret a biological phenomenon related to it, or solve a problem based upon it.  These submissions will be short, and should be used by you to focus your thinking on the topic of the day.  They also may be used by you on examinations in this course.  At the end of each class period, you will briefly assess your performance during the day, generally by analyzing your own behavior with respect to group or class participation.  These assessments will be brief and relatively informal and should help you to evaluate your understanding of each day’s work.

 

Exams – There will be four major examinations during the semester.  Each will be “essay” in structure and require you to frame answers to relatively complex questions that will test your mastery of the course material to that point.  They will be evaluated not only for correctness in understanding the basic principles of evolutionary theory but for clarity of expression as well.  You may work in groups or alone for each of these exams.  You generally will have one week for the completion of each.

 

Laboratories – We will have six scheduled laboratories during the semester.  Each will have its own specialized assessment.  Laboratories cannot be made up nor rescheduled.

 

Attendance

 

I believe that we all learn best in a cooperative setting, and from one another.  Thus I believe that it is imperative that you both attend and play an active role in every class period. Extraordinary circumstances may prevent you from making every class. As described above, you will receive credit for each class session that you attend and in which your performance meets basic expectations.  Class attendance will be recorded and excessive absences will receive a grade penalty. In addition to credit lost for failing to participate in a day’s class, each absence beginning with the fourth incurs an additional penalty of 1 point being deducted from your overall class average.  Please note that there are no excused absences from class periods.  In the case of extraordinary circumstances, please contact me as soon as possible to discuss your situation.

 

Disability Statement

 

If you require any accommodations to meet the requirements for this class, please inform me and I will work with you and the Office for Students with Disabilities to ensure that you will be able to perform as well as you can.
