Course news:
Course grades have been communicated to the Registrar and should be available from the Registrar. The grade distribution can be seen on the page of past grade distributions.
On Tuesday, 27 November 2007, we will go over our last creation story. We will then select four stories in a process where students will nominate candidate stories and then vote for their four favorites.
Exam II has been graded and will be handed back at the end of class on Thursday, October 18, 2007. The distribution of grades is shown below:

The offer of lunch with the professor on Tuesdays has been terminated on account of complete non-participation by students on the first six Tuesdays of the semester.
We will never have time to go over the "Marduk" story, so students are no longer responsible for that story.
Exam I has been graded and will be handed back at the end of class on Tuesday, September 25, 2007. The distribution of grades is shown below:

After five opportunities, no student has shown up for lunch with the professor. After one or two more opportunities with similar non-participation, the invitation to lunch will come to an end, solely for lack of student interest.

*Notes regarding readings:
All readings are in Stanley's Earth System History, except for web pages, which are labeled "WWW", and for numbers labeled "CS", which are nunbers for stories in Creation Stories from around the World.
Pages in brackets are not required reading, and they will not be used to generate exam questions. They are suggested reading that may make lecture material easier to understand.
Reading assignments do not include "Earth System Shift" ("ESS") inserts unless specifically noted.
Reading assignments include all figures to which reference is made, even if the figures fall outside the page range indicated. Figure 18.5 is a good example.

How to do better in GEOL 1122 or How to study for college exams.
A little bit of advice for first-semester freshmen.
A letter that student athletes can print out and use to request that their grades by reported to an advisor in the athletic program. After filling all the blanks, they should give the letter to Dr. Railsback.

Creationism
This GEOL 1122 section approaches the topic of creationism by reading a series of creation stories from cultures around the world. If you're interested in more direct arguments about American creationism, you might want to visit the following webpages with scientific views of creationism:
- - - Answers to FAQs about creationism and evolution at "Talk Origins"
- - - Mark I. Vuletic's list of creationist arguments, with responses
- - - Jim Merritt's somewhat flippant responses to creationist arguments
- - - George Bakken's evaluation of creationist arguments (scroll down past Darwin etc.)
Another page of interest might be one on the Scopes Trial.
Enthusiasts of the Hebrew Old Testament's stories of the earth's origin might be interested to read pages on
the origins of those stories, their authorship, and some of the scholarship about them.
