Supplemental Instruction Matt, TJ, Diana, Taylor www.usc.edu/si Final Review [email protected] BISC 120 Fall 2007 Page 1 of 17 A quick note from your SI leaders: We hope you guys have had a valuable learning experience this semester in BISC 120. It was a lot of fun working with you. You are all very bright and will go on to great things. Now breathe deeply, remember life is good, and rock this final! Edmands Extra Sections: Social Evolution: Campbell 51.5, 51.6 and R3 (online) “Selection for mating success” is also known as what alliterative selective mode? This selective force works: a. in opposition to natural selection b. in tandem with natural selection c. sometimes in tandem, sometimes in opposition to natural selection The elaborate tails of the male peacock, the large size of the female black widow spider relative to the male, and the extreme color variations in both sexes of mallards are all examples of what? In newts, females bear the burden of motherhood, whereas males provide little more than sperm. The number of sexual partners for female newts follows a standard distribution, whereas histograms for males demonstrate that a very small part of the male population has a disproportionate amount of sex. What is this known as? Remember Jabba the Hutt? It’s a little known fact that male Hutts have an internal pouch in which baby Hutts gestate. Female Hutts deposit eggs in this pouch soon after fertilization. Maturation of the fertilized eggs takes almost 3 standard galactic years (hardly a 12-parsec Kessel run!). Who is likely to be more promiscuous, Jabba or his sister Boonta the Hutt? _________ __________ is the type of selection used to explain altruistic behavior. By helping a related individual, an organism improves the chance at least some of its genes will survive. Altruism is most likely to occur in colonial species, where many individuals are closely related. Your little cousin fell and scraped her knee, but you are late for the Spice Girls concert. The cost (C) to you for missing the opener, as quantified by the Spice Girl Sadness Scale (SGSS), is .87. The benefit (B) to you and your cousin is .63, as quantified on the SFC (Stop Frickin’ Crying!) Scale. Your coefficient of relatedness (r) is approximately .125. According to the late WD Hamilton, are you likely to stop and help little Felicia? An evolutionary behaviorist would tell you that the real reason you are nice to unrelated strangers is because of: a. Altruism b. Hamilton’s Rule c. Reciprocal Altruism d. Fear of eternal damnation Yogi Berra is credited with the following quote: “I make a point of going to other people’s funerals, because otherwise they won’t come to mine.” Assuming Mr. Berra is talking of “other people in society,” and not the deceased, what is this an example of?
