Answer: Purple Evolution $500 Question: The more alike two different organisms are, the more recently they shared a __________ ___________. Answer: Common Ancestor Natural Selection $100 Question: What is the definition of Natural Selection? Answer: The survival and reproduction of the organisms that are genetically best fit for their environment Natural Selection Daily Double Question: The variety of dog and cat breeds that we have today are a product of _________ _____________. Answer: Artificial Breeding (Selective Breeding) $200 Natural Selection $300 Question: What are the name of the islands where Darwin studied and gathered much of his evidence for Natural Selection? Answer: The Galapagos Islands Natural Selection $400 Question: How does the overuse of antibiotics lead to resistant strains of bacteria? a. Antibiotics kill the bacteria that aren’t resistant leaving the more fit resistant bacteria b. Antibiotics genetically isolate too many bacteria to a population at one time. c. Antibiotics provide a breeding ground in which bacteria can flourish. d. Antibiotics change the structure of bacteria, making them resistant. Answer: a. Antibiotics kill the bacteria that aren’t resistant leaving the more fit resistant bacteria Natural Selection $500 Question: A little child catches a fly and pulls its wings off. The fly actually lives a better life, but does not pass its lack of wings on to its offspring because the loss of wings is an _________ _______.

Answer: behavioral Primates Adaptations $200 Question: A variation in an organism that helps it survive is called an ________________ Answer: Adaptation Primates Adaptations $300 Question : When an organism matches its surroundings in order to hide, this is an example of what type of adaptation? Answer: Camouflage Primates Adaptations $400 Question: When an organism imitates a harmful animal (ex. Coral snake imitating a king snake), it is an example of what?

Dog’s paw, human arm, bat wing, whale flipper Evidence for Evolution Question: Give the definition of an analogous structure. Answer: Body parts that share a common function but have a different structure. $300 Evidence for Evolution Question: When two organisms share a large amount of similar DNA, what does that tell scientists? Answer: they are closely related $400 Evidence for Evolution $500 Question: In embryology, when the embryos are very similar to each other, this means… ? Answer: the organisms had a common ancestor Misc. $100 Question: What is the ability of an organism to survive and reproduce in its environment. Answer: fitness Misc. $200 Question: This organism is thought to be the first life on Earth? Answer: prokaryotes (bacteria) Misc. $300 Question: A group of organisms that look alike and can reproduce are called this. Answer: A species Misc. $400 Question: Where did Ms. Densmore go to college? Answer: Appalachian State University Misc. $500 Question: Why, in evolutionary terms, is it important for new individuals to come into a population? Answer: They bring new DNA, which brings about evolution. Final Jeopardy Topic Evolution Final Jeopardy Question • Gazelles on the African plains are often hunted by the top predators. Over time, the gazelles have evolved to have very large eyes on either side of their head and very large ears. – How do their eyes and ears factor into their survival? – Explain how, through Natural Selection, gazelles have evolved to have these kind of eyes and ears. Final Jeopardy Answer • The eyes on either side of the head help them to see the predators coming from all directions. The large ears help them to hear the predators. • Over time, the gazelles that had poor hearing and vision were killed off. Those with better vision and hearing survived to pass those traits on to their offspring.
