EEB 5449 -- EVOLUTION

Fall Semester, 2014

NOTE: We are changing this site continuously, as the semester progresses.  Please visit it often! 

Food for thought, posted 2 years ago on CNN:
"The Gallup Poll has been tracking Americans' views on creation and evolution for the past 30 years.  In June [2012] it released its latest findings, which showed 46% of Americans believed in creationism, 32% believed in evolution guided by God, and 15% believed in atheistic evolution.  During the 30 years Gallup has conducted the survey, creationism has remained far and away the most popular answer, with 40% to 47% of Americans surveyed saying they believed that God created humans in their present form at one point within the past 10,000 years."

Syllabus and General Information

Each week, we will assign at least one original paper for you to read.  These articles should be read promptly.  At the end of the week, you will turn in a written "reaction" to that week's reading(s).  This should be sent to both of us via e-mail, in MS-Word format.  We will also accept printed copies, but these are less desireable.

Your reaction paper should include a brief summary of what the study found, the significance of those findings, and your critical reaction to the results and conclusions.  You can also include specific comments about the methods, discussion, conceptual context, or whatever else you think is important. The length of your response should be one to (at most!) two double-spaced pages.  On Tuesday (usually) of the following week you should be ready to participate in a class discussion of the paper or papers.

In addition, we might occasionally ask you to respond to a question in the textbook selected from the "Problems and Discussion Topics" included at the end of each chapter in Futuyma (2013).  These responses also should be no more than two double-spaced pages in length.

Chapters from Futuyma, 2013, are listed below and should be read before lecture.  Other assigned readings for your reaction papers, etc., can be downloaded using the links provided.  Links to PowerPoint lecture material (in PDF format) are also provided.  Let one of us know if you have difficulty retrieving anything from the course web site.

Note also the existence of two related articles, a critique of Zachos et al. by Gippoliti & Groves (dated 2012 for some strange reason) and a response by Zachos & Lovari (2013) to the G&G critique.  Skimming these additional articles will likely give you a better understanding of the original paper.
