o63 – Chapter 10 Evolution Study Guide Sections 10.1, 10.2, 10.3 -----Pages 296-317 1. When all the members of a species have died out, the species is ____________________. 2. Both genetic mutations/variations and environmental pressure affect ___________ by _______________________. 3. Traces or remains of organisms that lived long ago are called _____________. 4. Comparing the structures and DNA of two species sometimes show that the species have a __________________________. 5. Charles Darwin helped to explain how ____________________ change over time. 6. Scientists draw a ________________________ to show how whales are related to other species. 7. Characteristics that can help an organism survive and reproduce in its environment are called ___________________. 8. Survival of the fittest,, which basically states that organisms that are more fit for their environment will be more successful in surviving and reproducing, is an easy way to describe ____________________________. 9. The process by which populations slowly change over time is called ______________. 10. If an environment changes and the adaptations of a species don’t help it survive, it may become _________. 11. Beak shape is an example of a(n) __________________, since it helps the bird survive and reproduce. 12. Most of what scientists know about extinct species is based on the _______________________. 13. Required ingredients for the process of Evolution by Natural Selection include ____________, ___________, and ____________. 14. ____________ variations accumulate in a species through natural selection. 15. A required ingredient for Evolution by Natural Selection that makes it very difficult for us humans to actually see evolution occurring in our lifetimes is ___________. 16. Differences between members of the same species are called __________________. 17. _______________ create the variations in a species needed to drive Evolution by Natural Selection, unlike the Build a Beast assignment, which only required your imagination. 18. Drought, new predators, and natural disasters are all _____________________________. 19. Isolation of a species can be caused by a(an) ____________ or mountain range. 20. _________________ selection involves the breeding of plants and animals. 21. A group of organisms that can interbreed (reproduce) and have a fertile offspring all belong to the same __________. 22. The process of creating a new species is called ____________. Evolution Branching diagram mutations Natural selection island Environmental pressures extinct adaptation Mutations artificial WORD BANK for 1-22 species Environmental pressure speciation Natural selection isolation Natural selection fossils Evolution species variations Common ancestor Fossil record time adaptations Short Answer 23. What are 3 environmental factors or pressures that can lead to the extinction of a species? 24. Who are the baleen whales most closely related to in the branching diagram to the left? 25. The branching diagram shows that all the organisms in the diagram shared a __________________________. TASK Create a study tool of some kind based from the concepts in this unit, from this page. Your tool could be a test, wordsearch, crossword puzzle, jeopardy, song, or anything you can imagine. o63 – Chapter 10 Evolution Study Guide Sections 10.1, 10.2, 10.3 -----Pages 296-317 1.
