GEOL 159: Prehistoric Life Content of the Course Welcome to GEOL 159! This course is an introduction to the history of life on our planet, beginning with the first oceans over 3.5 billion years ago. Because paleontology is an integrative science, basic information from a number of disciplines such as biology, geology, and chemistry will be used to understand the big picture. However, this course assumes no prior knowledge of biology, geology, or chemistry other than a high school level background. Evolution is currently the only viable scientific theory for the origin and history of life. As a part of science, evolutionary theory necessarily excludes metaphysical considerations such as ultimate origins (where the universe came from and why it exists) and whether a supernatural entity or force has also influenced the origin of life and its history. However, this course will go beyond the bounds of science to examine metaphysical alternatives to evolutionary theory. In doing so, we will explore the relationship between scientific and nonscientific perspectives. What You Will Learn This course will cover the following topics: the scientific perspective the nature of life and the conditions and resources necessary for the maintenance of life the way that metaphysical explanations have shaped our views of the origin of life how fossils are formed, and how fossils and other scientific data are used to determine ages and the geological time scale the full range of life forms from the earliest bacteria to modern humans, excluding the plant kingdom what evolutionary theory entails and how it integrates scientific and historical data from many sources to explain the broad patterns of biological change through 3.8 billion years of Earth's history the origin of invertebrates and characteristics of major invertebrate taxa the origin of vertebrates and characteristics of their major groups evolutionary transitions linking fishes, amphibians, reptiles, birds, and mammals with their ancestral stock groups the nature of life in the Triassic Period, when mammals and dinosaurs first evolved the biology, life habits, classification, and evolution of dinosaurs
the genealogy of our own species human beginning with shrew like primate ancestors over 65 million years ago. Texts See course description for an up to date list of materials. Library Resources Students enrolled in Carolina Courses Online can access online library resources from the UNC Library System by linking to Distance Education Library Services. This site includes information on using general online reference works as well as accessing e reserves. If you are using an off campus computer, you will need to enter your UNC Onyen and password to access the library resources. The UNC library staff is available to assist any students who have difficulties accessing online library resources. If you encounter difficulties, please visit this webpage for reporting a problem and the Proxy Server Team will respond. Course Structure and Requirements Although this course is offered over the Internet, it is structured much like a regular classroom course, with a semester timetable, assignment deadlines, and exams. The course begins with the first day of classes at UNC Chapel Hill, and ends with the last day of final exams. Grading is based on the following formula: Lessons and assignments: 40 percent Midterm: 15 percent Final: 15 percent Discussion forum participation: 20 percent Paper: 10 percent All assignments are due by 11:59 pm Eastern time on the date indicated in the Schedule (see lefthand sidebar of the Sakai site). Midterm and final exams: The midterms and final exam will be emailed on the dates indicated in the course schedule and will have a specified time by which to complete and return them by email. Exams not returned by the specified time will lose points in proportion to the number of minutes they are late. Note that these exams are emailed via the class listserv in Sakai, so you must keep us informed of any changes in your email address. Discussion forum: The discussion forums will be online discussions of assigned topics between you and your group members or the class at large. Aside from posting your response to the primary discussion question, you must post at least two messages in the forum on two different days during each lesson to earn full participation points. Your participation in the forum will be monitored by
your instructor, who will engage with you on the discussion forum when appropriate. Please use the forum to ask questions about the readings, share ideas and opinions, and work with fellow students throughout the semester. Paper: You will turn in 800 1,100 word (12 point font, double spaced) paper on a scientific journal article pertaining to some aspect of paleontology (fossils, evolution, preservation, and so on your choice, as long is it's relevant to the course). Do not go over or under the word count, which includes everything in your file (title, paper, references, and so on). You must read a journal article from a journal such as Nature, Science, Paleos, and so on. Ask me if you need help finding an article. The paper will be worth 10 percent of your grade. It will consist of three parts: 1. A summary of the article and an explanation of why it is important/relevant. (two paragraphs) 2. A critique of the article based on what you've learned in the class; that is, is the information correct? Is it thorough? How well did the author explain the material? What did the author do well? What needed work? (two to three paragraphs) 3. Four or five open ended questions that the article brought up in your mind about the research or what the next step is for research. You must also provide a complete reference for the article (title, author name, journal/paper name, volume, and so on). Expectations: All assignments must be written in your own words. If you acquire information from sources other than the text (other websites, journals, and so on), then those sources must be clearly and completely cited in your work. You should avoid close paraphrasing and frequent quoting from the text or other sources. Your assignments should show me that you have a firm grasp of the material; relying too much on the wording and structure of the text suggests otherwise. If cheating or plagiarism is suspected, you will receive one warning. Subsequent suspected incidents will be reported to the Honor Council. You are expected to read and understand the Honor Code (see Honor Code section below).
