BIEB 150
Evolution
Winter Quarter 2019
Instructor: Lin Chao
Office Hrs: By appointment. The instructor will always be available after lectures to answer questions. However, if students require additional help on lecture materials, the instructor requests that students first try to address their questions to the Instructional Assistants’s during section meetings. Because of the size of the class, the instructor cannot meet on a regular basis with individual students. If problems and questions cannot be satisfactorily addressed during section meetings, students are of course welcome to approach the instructor for clarification. If students have general questions or issues (topics not covered by present lectures, suggestions of possible lecture topics, ways to improve the course, career choices in biology, etc.) they are also welcome to approach the instructor. Phone: 858 822 2740; Email: [email protected]; office: 3401 Bonner Hall.
Instructional Assistants (IA’s):
To be announced.
Lectures: Tuesday/Thursday 2:00PM – 3:20PM, York 2622
Sections: No Sections the first week of lecture. Sections start the second week. Check the Schedule of Classes for section times and meetings rooms. Please follow additional announcements in lecture. Sections are supervised by the Instructional Assistants. Attendance of sections is highly recommended, but not mandatory. You can attend any scheduled section. The goal of the sections is to provide a chance for students to discuss, review and clarify material covered during the lectures. The attendance of sections is not a replacement for attending lectures.
Midterm: To be administered in the same room as lectures, unless otherwise anounced. See attached Lecture Schedule below for date and time.
Final Exam: NOTE: Final exam is of the same duration as the midterm (80 minutes), although the Schedule of Classes reserved a much longer time slot. See attached Lecture Schedule below for actual date and exact time. The Schedule of Classes has not assigned a room for the final exam at this time (one week prior to first lecture). Please follow anouncements in class lecture and to your UCSD.edu email account for the location of the final exam.
Recommended Text: Evolutionary Analysis , 4th^ Edition, by Scott Freeman and Jon C. Herron.Purves, Pearson Education, Inc., 2007. Recommended for additional reading, but not required. COURSE GOALS
BIEB 150 offers an introduction to evolution. In this class, the process of evolution is taken from the perspective of a population. In biology, we can study how molecules are assembled to produce cells. Although some organisms are single-celled, we can also study how cells are in turn assembled to create more complex organisms. If we go one level higher, we find that organisms exist in populations. The goal of this course is to understand how interactions at the population level can help us understand the evolution of organisms.
This course is more theoretical and mathematical than most courses in the biological sciences. The objective is to develop a framework to understand and think about the process of evolution, instead of providing a large body of facts to substantiate evolution. Algebra and genetics are used extensively, so you will be expected to be comfortable with both.
PREREQUISITES AND REQUIREMENTS
BILD 1 and 3 are prerequisites for this course. Although I try to review background material whenever necessary, materials familiar to most students cannot be reviewed in detail. If you have difficulties recalling some of the basic information, I suggest that you review it by going over an appropriate introductory text book. If you need a refresher or review, please take it as early as possible and not after you have fallen behind.
Although math classes are not a prerequisite for BIEB 150, math and algebra are used extensively in the course. As stated earlier, you will be expected to be comfortable with math, especially algebra.
ADVICE
Because the lectures in this couse build on material from previous lectures, you will be seriously hurt by missing lectures. Reading the text book helps, but the text is meant to supplement and not replace the lectures. Nothing really replaces attending lectures and taking your own lecture notes. Learning to listen to a lecture and then recording your own notes, by your own hands, is an invaluable skill. Take extensive and complete notes. Recording only an outline of the lecture is not sufficient. Record everything that is stated or presented on the chalk board. You will find that you will retain much more information if you force yourself to listen and then translate the information into your own notes. Learning by listening and taking notes is possibly the single most important skill that you can acquire from four years of college education. Most information you learn from your classes will become outdated. Listening and taking notes will never become outdated, despite whatever new communication technologies might arise, and they will allow you to continue to learn.
made and photographs will be taken. Documented cheating will result a failing grade for the course and report to the UCSD Office of Academic Integrity.
MAKE-UPS AND REGRADES
A valid excuse for missing an exam is a medical or family reason. Appropriate documentation (for example, letter from doctor) is required. Extraordinary circumstances will be considered on a case by case basis by the instructor. Make-ups for exams will be given only with a valid excuse.
A make-up exam will be given at a later time to be arranged between the student and instructor. The format of the make-up exam (written, oral, essay, multiple choice, etc.) will be decided by the instructor. If you miss an exam without a valid reason, you will receive no points for that exam.
Regrades can be requested only if there are errors in either the addition of points or the reading of your answers. If a regrade request is made, the entire exam will be regraded. If regrade changes are in your favor your score will be increased. If regrade changes are against you, your score will be lowered. WARNING: Because of previous problems, all exams will be photocopied before being returned to students. Do not modify your exam after it is graded when asking for a regrade. Regrade exams found to be modified will be sent to the UCSD’s Office of Academic Integrity.
An answer key will be provided to you after your midterm is graded and returned. Please use the answer key to evaluate if you have been graded incorrectly. However, bear in mind that what matters in grading is what you knew and recorded at the time you took the exam and not what you know later or after the answer key is provided. Graders can only give you credit for what was stated on the proper areas of the exam sheets.
Requests for regrading of exams must be made in writing within one week after exam is returned and/or answer key is posted. Please explain concisely what errors were done. All additional communications on regrade between the instructor and student will be conducted by email. The instructor will not meet one on one with students to discuss grades and regrades.
An answer key will not be provided for the final exam. Additionally, your final exam will not be returned and it will be kept on file as a record. If you wish to see your final exam, appointment times will be made available the following instruction Quarter.
