Course summary: ANT3930 is an in-depth examination of the use of molecular genetic data to address questions of human evolution and population genetics.  The completion of the human genome sequence has greatly facilitated the application of molecular genetic data to questions of human evolution.  Over the past ten years, a wealth of genetic data has been generated on human populations worldwide and new statistical methods have been developed to analyze these data.  These genetic data are currently being used in a number of investigations, such as the reconstruction of past migration events or the detection of admixture or gene flow in a population.  Specific topics to be discussed include the relationship of humans to non-human primates, emergence of anatomically modern humans in Africa and migration out of Africa, Neanderthal genetics (did we interbreed?), colonization of Europe and the New World, genetic ancestry in the public domain (National Geographic's Genographic Project), and ancient DNA studies.

 

Course design: This course is intended for advanced undergraduate students who have an interest in human evolution as well as in molecular genetics.  It is intended for students from all colleges and departments – in the past, I have had students from anthropology, chemistry, history, molecular genetics and microbiology, and zoology.  A diverse audience makes for a more interesting class since everyone has different backgrounds, different perspectives and different interests to contribute to class discussions.  Active participation is one of the strengths of the class in this regard.

 

Course objectives and student goals: All students are expected to gain knowledge on the molecular genetic basis for various theories of human evolution and subsequent population movements.  The class is fairly intense and demanding because knowledge across a broad range of fields is fundamental to an exploration of the molecular genetics of human evolution – in fact, this course may be the most challenging course you have ever taken with respect to developing expertise and familiarity with a wide range of materials, techniques, publications, etc.  You are expected to do all of the required readings and to follow up with additional readings if you do not understand a topic or concept.  Additional readings are listed in the textbook and can be found in the references in the journal articles; furthermore, you should become familiar with searching PubMed for supplementary, follow-up, or original readings.

 

Reading and course format: Reading material consists of one textbook (Human Evolutionary Genetics by Jobling, Hurles, and Tyler-Smith) and a course pack of approximately 30 related journal articles plus ‘news and views’ type articles (the textbook and course pack are available at Orange and Blue Textbooks, 309 NW 13th St, 375-2707).  If students know of additional articles or topics that they would like to discuss, please contact me.  The course meets once per week for three hours and the course format is mainly discussion with substantial student participation.  Lectures will be supplementary only in order to provide necessary introductory and background material.

           

Grading: Final grades will be determined by the following five categories, each of which contributes 100 points to the final grade: 1) participation (100 pts), 2) weekly summary/questions/comments (100 pts), 3) 2-4 homework exercises (25-50 pts each), 4) one oral presentations (100 pts total), and 5) one exam (100 pts).  Possible points total 500.  Grades will be based on the following point percentages: 90-100%=A, 87-89%=B+, 80-86%=B, 77-79%=C+, 70-76%=C, 67-69%=D+, 60-66%=D, < 59%=E.

-                      Participation is required of all students and will be based on each student’s contribution of original comments, questions, etc to the class.  Students are not graded on the brilliance of their statements, but on their willingness to talk, a demonstration that the assigned material was read, and the originality of their comments.  Simply showing up for class does not constitute participation.  Remaining silent in class means that the highest grade a student can receive is a B.

-                      At the beginning of each class, a 1-paragraph summary and 2-3 questions or comments for each peer-reviewed journal article assigned for that day’s class will be turned in.  The summary/questions/comments are required only for the peer-reviewed journal articles, not for the news-and-views type articles (typically the titles that are in quotes in the course schedule below) that are included in the course pack to provide background or summary information.  The summary/questions/comments are intended to ensure that each student is prepared to actively participate in class discussions.

-                      There will be a maximum of four homework exercises involving the analysis of hypothetical or actual molecular data.  The exercises are intended to give students an opportunity to perform data analyses similar to those conducted in the discussion papers and will be graded on effort and accuracy.  Exercises must be turned in two weeks after they are assigned.  Students who miss the class in which an exercise is assigned are expected to turn the exercise in on time, i.e. two weeks after the missed class.

-                      Each student will present one 15-20 min oral presentation based on journal articles from the course packet.  The presentation must use MS Power Point.  Regardless of whether a student is presenting an article, all students will read all articles in the course packet and be prepared to participate in class discussions of the articles.  Students will sign up for articles for oral presentation on the second day of class (only one student may sign up for each article).

-                      There will be one exam that will consist of short answer and essay questions and questions similar to the homework exercises.  Questions must be answered during the class period without reference to books or notes of any kind.  Calculators may be used, but no cell phones, BlackBerry or similar devices will be allowed.  Make-up exams will be scheduled only in extenuating circumstances and will require a doctor’s note, police report, or similar supporting documentation.

Class attendance policy: Because the class meets only one time per week and because the class format is mainly discussion, it is very difficult to make up missed classes by borrowing notes, etc.  Therefore, students are strongly encouraged to attend all classes and to arrive on time.  Computers are allowed in class for taking notes, but are not allowed during exams.  Class discussions/lectures cannot be recorded in any manner without special permission.  All cell phones must be turned off during class.

 

Strategies for success:

-          It is important to complete all the readings on time and it is best to do the readings throughout the week.  In this way, you have time to think about and process the information during the week and in between different readings.  Ideally, you would read some every night of the week.  The amount of reading material is very modest, particularly for an anthropology course.  This is because it is expected that you will re-read (gasp!) anything you do not understand the first time.  I often re-read journal articles and find myself discovering things that I completely missed on the first read.  Or new items will come to light after having read a different, but related article.  This is the intent of the readings – that they relate to each other and increase your knowledge and expertise in an exponential way.  During your reading, you should take copious notes and these notes will form the basis of the summary + questions you must turn in for every article.

-          You have two weeks to work on the exercises.  These exercises are most likely completely different from anything you’ve ever done and, thus, you may have lots of questions about how to proceed.  The intent is that you will use the first week to start on the exercise and come to class the next week (i.e. the week before the exercise is due) with any questions you have about the exercise.  Do not wait until the second week to start the exercise.  Also, I am always available by email to ask questions about the exercises and often will be able to answer your question immediately while you’re still working on the exercise.

-          For the oral presentation, it is a good idea to practice your entire presentation without any stops the night before your scheduled presentation – this ensures your talk is the correct length of time and develops good practice for all public speaking.

-          Finally, you should review material throughout the course rather than trying to cram everything in the night before the exam.  Ask for help in taking notes, comprehending the material, or preparing any of the written or oral assignments – I am available during office hours, you can schedule an appointment outside of office hours, and I am always available by email.
