Deuterostomes
Lab

NOTE:
Lab
practicals
will be offered on
Sunday,
November
22,
Monday, November 23, and Tuesday, November 24. 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 25. 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.
This is the new Fig. 1 to replace the figure on page L66 in your Survival Manual.
- Attend the Deuterostome Evolution lecture on November 10 in
HEC Auditorium in Goldwin Smith at 9:05 am.
- Review pages 536-543, 654-664, 693-695, and 698-721 in Campbell
and Reece.
- 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.
- Complete the deuterostome lab objectives on pp. L57-L62.
- Be prepared for a short quiz on pages 536-543 and 654-664 in
your text and objectives 1-8.
- Bring the lab guide (pp. L55-L141) to lab.
- Be certain to clean up after yourself in lab.
Students who fail to clean up after themselves will lose points!
- 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.
- Take the practical exam. The exam will have both written and practical
portions. The practical portion will consist of ~25 stations with
4 questions at each station. You will have 90 seconds at each station.
Note: NO MAKE-UP PRACTICAL will be offered.

- A
larval revelation - Identification of the previously unknown
larval forms of the sea lilies, a group of marine invertebrates,
is a refreshing reminder of the value of descriptive science
in evolutionary studies.
- Zoology:
Larva flow - Properties of sea lily larvae provide support
for Garstang's proposal that the chordate central nervous system
derives from the ciliated bands of an ancestral chordate tadpole
larva.
