You should be able to answer practice questions associated with the lab manual sections covered since exam 2; focus on the kinds of question about which you had to do homework or about which we had discussions in lab. Be sure you can do ALL the practice questions that were assigned as homework (not just the ones you had to do for your homework.) Don't forget that you can review the old lab discussions on the web (except the one we did in person.) Don't forget the one we did in person -- you will certainly have to draw and/or interpret phylogenies in relation to topics such as testing for adaptation, species selection, and the relationship between embryogeny and evolution.
The only new reading from the textbook that is covered on the exam is the material on gene regulation, evolution, and embryogeny from chapter 12 (sections 12.2 and 12.3). NOTE that I have posted the answers to the practice questions you did for homework on this material; the material from these three questions is what you need to know from these sections of the textbook.
From the material related to the critique and the "warm-up" paper on the web, there WILL be an essay question in which you will need to explain one of the sentences from the "warm-up" paper on the web, including one of the terms in bold-face, and you will have to explain something about whether it is a good or bad aspect of a phylogenetic study. I will give you a choice of three of these (you will choose to answer one of the three options I give you on the test -- I won't tell you ahead of time what the three will be.) They will be aspects of this paper that we discussed during the lab discussion of the "warm-up" paper.
For material that is comprehensive, you should know basic processes of evolution as they apply to the recent material, and you should know the material presented with the key to exam 2 that people had difficulty with on exam 2.
