Class meets: Tuesdays and Thursdays, 8:45AM -10:00AM Prerequisite: BIO107 Attendance: Attendance is required. If you miss more than about six classes you should let me know why. Required Text: Principles of Development, 4 rd Edition, Lewis Wolpert, et al.

Instructor: Dr. David Champlin Office: 305B Science Building, Portland Office Phone: Office Hours: My office hours will be Tuesdays and Wednesdays, 12:00 - 2:00 PM, but you can make an appointment to meet with me at just about any time. Here is a link that can help you with that: W.htm W.htm

Web Resources: A copy of this syllabus is available at: At this site are copies of the exams from the previous time this course was taught. My goal will be to post the PowerPoint presentations I use in lecture at this site also as well as a recording of the lecture for one week.

The maximum number of points for the course is 520 as follows: Each is described in more detail on our course web site: review paper worth 100 points two short writing assignments each worth 20 points two exams each worth 100 points cumulative final worth 100 points five quizzes each worth 20 points five in-class assignments each worth 20 points No make-ups for missed quizzes or in-class assignments, but you can drop the lowest two scores of the ten total quizzes / assignments. Each quiz will be announced at least a week ahead of time, but the in-class assignments won’t be announced ahead of time.

Lewis Wolpert = author of our book

What is developmental biology? Lewis Wolpert = author of our book "What is the one thing everyone should learn about science?" Wolpert responded: I would teach the world that science is the best way to understand the world, and that for any set of observations, there is only one correct explanation. Also, science is value-free, as it explains the world as it is.

You have made your way from worm to man, and much within you is still worm. Friedrich Nietzsche, 1883, from Also Sprach Zarathustra Caenorhabditis elegans C. elegans

Caenorhabditis elegans = C. elegans nematode

The 2002 Nobel Prize in Medicine was awarded to these scientists for the use of C. elegans to understand programmed cell death (PCD).

A fertilized nematode egg and early embryos as viewed with Nomarski optics = Differential Interference Contrast (DIC).

As each C. elegans worm grows from the fertilized egg, it has an invariant cell lineage.
