April 6, 2005 Review for Midterm #2: Evolution What to study : The exam will cover only lecture material. You are responsible for reviewing all the material that was covered in class (up to Lecture 12 inclusive, “Biogeography”). There will no doubt be some material on the midterm that is not mentioned in this handout or in the review session. You may find it helpful to review the textbook, because Professor Slatkin used many examples from the textbook. However, if a topic was only covered in the textbook or lab manual, and not in lecture, it won’t be on the midterm Question format : About 1/3 to 1/2 of Professor Slatkin’s questions will have multiple correct answers . You must fill in more than one bubble on your Scantron. You must choose ALL the correct answers and ONLY the correct answers, otherwise, you will get 0 points. Here is an example: “Which of these animals are mammals?” Full credit: No credit: No credit: (a) monkey (b) bird (c) turtle (d) dolphin (e) wolf (a) monkey (b) bird (c) turtle (d) dolphin (e) wolf (a) monkey (b) bird (c) turtle (d) dolphin (e) wolf This makes the exam more challenging because each multiple-answer question now has (2 5 ) = 32 possible answers instead of 5. To make your life a little bit easier, Professor Slatkin has designated the possible multiple-answer questions as follows: (M) Which of these animals are mammals?” If a question is not preceded by an (M), then it does not have multiple answers. However, if it is preceded by an (M), it does not necessarily have multiple answers. It might only have one. Other opportunities for midterm review: Student questions and GSI answers on the class website: http://ist- socrates.berkeley.edu/~akerr/bio1b/questions-evolution.html . Will be posted by Thursday 8 a.m. Professor Slatkin’s review session on Thursday, 6-8 p.m., 1 Pimentel. Q-and-A format. Amber’s office hours: Thursday, 3:40 - 5:00 p.m., 2013 VLSB. (This week, Amber will be in the office until 6:00). Ruth’s office hours: Thursday for two hours. Contact Ruth for details. Also, don’t hesitate to e-mail Ruth ([email protected]) or Amber ([email protected]) with

any last-minute questions. Topic outlines The history of evolutionary theory - There are three parts to any theory of evolution: fact , theory , and mechanism . - We now generally agree that natural selection is the most important mechanism, but other mechanisms were proposed too. - Plato : every species has an“ideal type .” Any deviation from ideal type an imperfection. This idea does not support evolution because it ignores the importance of variability, and assumes fixed “types.” - Aristotle : Nature tends toward increasing perfection . This also conflicts with our current understanding of evolution, because it cannot account for all the extinct species, diverse forms, and unsuccessful body plans that we see. -
