BIEB 166: Animal Communication & Behavior Initials:____________________________ First Midterm Exam: April 30, 2007 Page 2 of 9 total student points on this page:______ Please apply the concept of Tinbergen's Four Questions to the following example : While studying the behavior of animals living in hydrothermal vents, you come across an interesting and previously unknown type of jellyfish. If a crab approaches the jellyfish, it glows bright red (due to its ability to bioluminesce) and the crab backs off. Crabs eat other similar-appearing jellyfish and you never observe these eaten jellyfish glowing red. You form the following hypotheses: (a) The jellyfish that are eaten by crabs are a different species from the jellyfish that glows red. (b) The red glow acts as a warning, indicating that the jellyfish is dangerous to eat. (c) The bioluminescent cells capable of glowing red developed as the jellyfish matured. (d) Jellyfish that were capable of glowing red to advertise their toxicity survived and reproduced more than jellyfish that could not glow red. (e) Through a chemical reaction, proteins inside the jellyfish's bioluminescent cells release red light. 1) (2 pts) Which hypothesis fits into the category of "causation"? _____ 2) (2 pts) Which hypothesis fits into the category of "function"? _____ 3) (2 pts) Which hypothesis fits into the category of "evolutionary history"? _____ 4) (2 pts) Which hypothesis fits into the category of "development"? _____ IMPORTANT! For multiple choice questions, there is only one correct or best answer per question. Circling more than one answer per question is incorrect. 5) (4pts) As discussed in lecture: (a) Fly maggots use negative photokinesis to move away from the light. (b) When a male silk moth is initially searching for the sex pheromone produced by the female silk moth, he uses positive anemotaxis....
