Using a specific example from lab of a vertebrate morphological or behavioral characteristic as illustration, discuss the action of natural selection in the evolution of adaptation.
You should expect something about systematics.
Briefly describe (don't just list) the five unifying synapomorphies of the Phylum Chordata.
Why are hagfish referred to as "honorary vertebrates"?
Briefly describe the role of the visceral skeleton in the evolution of jaws, jaw supports, and braincase elements.
Briefly distinguish between protostomes and deuterostomes.
Here is an example of what you will likely find at the beginning of the exam:
There are five essays, of variable point value (stated with each question;
70 points total). Answer either question 1 or 2, question 3,
either question 4 or question 5, and any two of questions 6, 7, or 8. Please
write clearly and concisely, using proper grammar and scientific vocabulary.
Be as specific as possible in your answers, and answer only the questions
asked, with a minimum of superfluous information. Be aware that because
of constraints on your time, many important points are not addressed on
this exam -- do not answer questions that I do not ask. Also please avoid
redundancy in your answers -- in general, there is no overlap between the
questions. I expect essays that are series of statements strung together
into a logical and cohesive unit; each essay requires you to make specific
points for full credit. You may use labeled sketches or outlines where
specified. Some essays ask for interpretations or speculation in addition
to factual information. You should justify your interpretations using factual
information about morphology, ecology, or other phenotypic characteristics.
