Deuterostome Evolution Lab

NOTE: Enrollment in the Deuterostome Evolution Lab will be completed on the bulletin board in the Study Center, beginning at 12PM on October 31.

NOTE: Lab practicals will be offered on Monday, November 21, and Tuesday, November 22. When signing up for your lab session and practical, keep in mind that the Thanksgiving holiday does not begin until 1 pm on Wednesday, November 23. Plan your travel accordingly. There will be NO MAKE-UP EXAMS offered.

ALSO NOTE: You will dissect a specific organism in the lab but are responsible for learning the material for all the animals discussed. This will require study outside of lab.


To prepare for your scheduled lab section you must :

  1. Attend the Deuterostome Evolution lecture on November 8 in Uris Hall G01 at 9:05 AM.
  2. Review pages 536-543, 654-661, 693-695, and 697-720 in your textbook.
  3. Read the lab guide in the Survival Manual (pp. L55-L97) before lab, and the dissection instructions for the specimen that you signed up to dissect in lab.
  4. Complete the deuterostome lab objectives on pp. L57-L62.
  5. Be prepared for a short quiz on pages 536-543 and 654-661 in your text and objectives 1-8.
  6. Bring the lab guide (pp. L54-L140) to lab.

After Lab:

  1. Be certain to clean up after yourself in lab. Students who fail to clean up after themselves will lose points!
  2. Come to the Study Center early and often to learn the anatomy of the animals you did not dissect in lab. Specimens will be available and TAs will be around to help.
  3. Take the practical exam. The exam will have both written and practical portions. The practical portion will consist of ~22 stations with 4 questions at each station. You will have 90 seconds at each station. Note: NO MAKE-UP PRACTICAL will be offered.
