2 1. Fossil Records 2. Homologous Structures 3. Vestigial Structures 4. DNA Evidence 2

3 1Fossil Records= All of the fossils collected. 2 *The most complete fossil record of evoluonary change is the horse. Homologous Structures= Body parts that have the same basic structure, but in different organisms *Homo means same. Ex: The lion`s leg, a bird`s wing, & a dolphin`s flipper & my hand! 3 Vesgial Structures= Body parts that have no funcon. Ex: Appendix Whale hind leg bones 4. DNA Evidence Scienst study an organism`s DNA to learn more about evoluon. To learn how organisms are similar or different EX: Dogs and bears have very similar DNA, which means they could have evolved from a common ancestor. 3

Species 3. Sciensts believe that all dogs descended from the. A. Woolly Mammoth B. Grey Wolf C. Eohippus 4. A sudden change in a gene is called a? A. Replicaon B. Decomposion C. Mutaon 5. Traits that help an organism survive in it`s environment are known as. A. Adaptaons B. Dominant Genes C. Autotrophs 6. Good mutaons are also known as. A. Mutaons B. Adaptaons C. Carriers 7. A frog with albinism has a mutaon. A. Helpful B. Necessary C. Harmful 8. A chameleon is able to change different colors in its environment,this is known as a(n). A. Successful color change. B. Adaptaon C. Coloraon 9. The survival of offspring that have favorable traits is. A. Natural Selecon B. Survival of the Fiest C. Both A & B 10. Sea turtles have about fiy to two hundred eggs. Many of these sea turtles do not survive to maturity, this is known as. A. Struggle to Survive B. Overproducon C. Malnutrion 11. For Valenne`s Day you receive a bouquet of roses. Some of these roses are pink, purple, red, and white, this is known as. A. Genec Variaon B. Pollinaon C. Botany 12. Two grizzly bears in the woods are in compeon with each other over food, water, a mate, and the habitat itself, this is known as. A. Compeon B. Liming Factors C. Struggle to Survive 13. The key to natural selecon is. A. Successful Reproducon B. Overproducon C. Ecology 14. Before the Industrial Revoluon in Manchester, England the populaon of peppered moths was, the populaon of dark colored moths was, and the trees were in color. A. low, low, dark B. high, low, light C. high, high, light 15. During the Industrial Revoluon in Manchester, England the populaon of peppered moths was, the populaon of dark colored moths was, and the trees were in color. A. high, low, dark B. low, low, light C. low, high, and dark 16. The peppered moths of Manchester are an example of. A. Overproducon B. Natural Selecon C. Successful Reproducon 17. The Wooly Mammoth is an example of a(n) species. A. Living B. Surviving C. Exnct 18. Most fossils are found in rock. A. Igneous B. Sedimentary C. Metamorphic 19. The most complete fossil record of evoluonary change is the. A. Dinosaur B. Grey Wolf C. Horse 20. Your hand, a bat`s wing, and a dolphin`s slipper are all examples of structures. A. Decomposed B. Vesgial C. Homologous 21. Your appendix found in your body, and a whale`s hind legs are both examples of structures. A. Decomposed B. Homologous C. Vesgial 22.DNA evidence, fossils, homologous structures, vesgial structures, and bones are all that supports evoluon. A. Cycles B. Evidence C. Lipids 8
