Only the printed number, no bubbles! E. None of the above are correct Extra Credit — you’ve been asking for this all semester long! This is the only absolutely fair way that I could think of to do this, since most everybody is here taking this test, and you only have so much time, the same as everybody else, to do it. Furthermore, I will have the time to read and evaluate your answers over the Thanksgiving break. This can count as much as any one sectional exam, that is up to 10% of the entire class grade, enough to easily move you from one grade bracket to the next, if you do well enough: On the back side of the Scantron answer sheet write a complete paragraph or more about the joke I made last time: “There is no bone in your boner.” Remember, I told you that most mammals, including all other primates, do have a bone in their penis called the baculum, but Homo sapiens lost it in their evolution. A few other mammals also secondarily lost the baculum — including horses, rabbits, hyenas, and whales — and it is quite reduced, but present, in the other Great Apes. Why do you think that humans lost the baculum in their evolution? Try to use sound evolutionary thought in your answer. What possible adaptive advantage could be attributed to this loss? You need to use complete sentences, and make sense. I will give partial credit, from 0 to 10, depending on content and how well you explain yourself. Proper English writing form matters! 13 Organismal Biology Section Four Exam Key 1. The study of the function of all of the body's parts is: A. Physiology B. Anatomy C. Pathology D. Histology E.
