Answer History of the Earth 200 What type of dating determines the ages of rocks by comparing them with other layers? Answer History of the Earth 300 What type of dating provides a more accurate age of a fossil? Answer History of the Earth 400 What ages of fossils can Carbon-14 be used for? Why? Answer History of the Earth 500 How has continental drift influenced the evolution of organisms? Answer Darwin’s Theory of Natural Selection 100 True or False: Organisms that are more closely related have more similarities in their genes (DNA) Answer Darwin’s Theory of Natural Selection 200 How did the fossil record influence Darwin? Answer Darwin’s Theory of Natural Selection 300 How did Darwin’s observations on the Galapagos Islands influence his ideas of natural selection? Answer Darwin’s Theory of Natural Selection 400 What are the four principles of natural selection? Answer Darwin’s Theory of Natural Selection 500 What is the relationship between evolution and natural selection? Answer Evidence of Evolution 100 Give an example of a specific animal’s adaptation Answer Evidence of Evolution 200 What is geographic isolation? Answer Evidence of Evolution 300 What structures develop from similar tissues, but meet different needs in an adult? Answer Evidence of Evolution 400 What type of structures would we consider bird wings, bat wings, and insect wings? Why? Answer Evidence of Evolution 500 Explain 5 pieces of evidence for evolution. Answer Shaping Evolutionary History 100 What causes genetic drift to occur? Answer Shaping Evolutionary History 200 In which type of selection do both ends have higher fitness than the middle? ex: Large and small male cichlid fish, but very few medium size males Answer Shaping Evolutionary History 300 The changing of beak sizes in the finches on the Galapagos islands is best represented by which type of selection? Answer Shaping Evolutionary History 400 What generally happens when reproductive isolation occurs? Answer Shaping Evolutionary History 500 Contrast adaptive radiation and convergent evolution. Answer MISC 100 What does fitness mean for an organism? Answer MISC 200 What is the pattern in which there are long periods of stable, no change, interrupted by short, rapid evolutionary change? Answer MISC 300 What type of structures are the human appendix, human tailbone, snake leg bones, and whale pelvis? Answer MISC 400 Homologous structures are a sign of ___________ b) Analogous structures are a sign of ___________ a) Answer MISC 500 Which of the following would favor giraffes with the shortest necks? Why? A. B. C. Answer History of the Earth 100 - Answer Sedimentary Game Board History of the Earth 200 - Answer Relative Dating Game Board History of the Earth 300 - Answer Radiometric Dating Game Board History of the Earth 400 - Answer Once living organisms (contained Carbon) that are less than 100,000 years old. The half-life of Carbon-14 is approximately 5,700 years, so there would be too little Carbon-14 left to measure after 100,000 years. Game Board History of the Earth 500 - Answer As continents slowly moved, populations of species were separated. Those that adapted to new climates probably evolved into new species after many generations. Game Board Darwin’s Theory of Natural Selection 100 - Answer Game Board Darwin’s Theory of Natural Selection 200 - Answer It shows that organisms have changed over time. Earth is old enough (4.6 billion years old) for these changes to occur. Game Board Darwin’s Theory of Natural Selection 300- Answer Maybe the different species of finches on different islands had once been part of the same species. They had adapted over time to the conditions on each island. Game Board Darwin’s Theory of Natural Selection 400 - Answer 1. 2. 3. 4. Variation Heritability Overproduction Reproductive Advantage Game Board Darwin’s Theory of Natural Selection 500 - Answer Natural selection is one way of how evolution works. Evolution is how species change over time (generally due to natural selection). Game Board Evidence of Evolution 100 Answer Many answers could be correct – as long as it is a characteristic that increases the survival and reproductive success of that animal. Ex: stripes of a tiger to make it more camouflage, the long legs of an ostrich to increase speed, etc. Game Board Evidence of Evolution 200 Answer When populations are separated by barriers such as rivers or mountains. They become isolated and will eventually evolve into separate species. Game Board Evidence of Evolution 300 Answer Homologous structures - From a common ancestor Game Board Evidence of Evolution 400Answer Analogous structures - They appear to be similar on the outside, but are different on the inside structurally (anatomically). They did NOT evolve from a common ancestor. Game Board Evidence of Evolution 500 Answer 1. 2. 3. 4. 5. Fossil record Comparative anatomy (homologous structures AND vestigial structures) Comparative embryology Comparative Biochemistry (DNA) Geographic Distribution ***Why is each evidence for evolution??? Be specific (I’m leaving this one up to you ) Game Board Shaping Evolutionary History 100 Answer Random chance (NOT due to natural selection) - Natural disaster could wipe out a large portion of the population, or overhunting (elephant seals), or a small group moves away Game Board Shaping Evolutionary History 200 - Answer Disruptive selection Game Board Shaping Evolutionary History 300 Answer Directional Selection Game Board Shaping Evolutionary History 400 - Answer Speciation - A new species evolves because they eventually evolve enough changes that they no longer reproduce with the original population. Game Board Shaping Evolutionary History 500 Answer Adaptive radiation – new species evolve from a common ancestor (branching tree), generally rapid growth as the organisms adapt to new conditions Convergent evolution – unrelated species evolve similar adaptations (analogous structures), but they do not share a common ancestor Game Board MISC 100 - Answer The ability to survive and reproduce Game Board MISC 200 - Answer Punctuated equilibrium Game Board MISC 300 - Answer Vestigial Structures Game Board MISC 400 - Answer a) Adaptive radiation b) Convergent evolution Game Board MISC 500 - Answer C. Though disruptive selects for the shortest AND longest necks, it is the only graph shown that does select for short necks. Stabilizing stays stable (middle lengths). The directional graph moves in the direction of the longer necks.
