EVOLUTION STUDY GUIDE QUESTIONS

This study guide covers key concepts in evolution and natural selection, including genetic variation, survival of the fittest, and the four principles of natural selection. It explores important terms like phenotypes, speciation, and the significance of overproduction in ensuring species survival. The guide provides answers to critical questions about adaptations, anatomical structures, and biodiversity, including examples from Darwin's research, such as the finches of the Galapagos Islands. It's an essential tool for students preparing for assessments in evolutionary biology.

  1. EVOLUTION STUDY GUIDE QUESTIONS Messana 2013-2014

  2. Q 1: When organisms have genetic variations that lead to higher rates of reproduction and survival, this relates to _______ _____________

  3. Answer: NATURAL SELECTION

  4. Q 2: What is the purpose of OVERPRODUCTION?

  5. Answer: Overproduction helps ensure that some organisms survive and can reproduce to avoid extinction

  6. Q 3: When the same type of bird has different shaped beaks to assist in eating, this is referred to as ________ __________

  7. ANSWER: Genetic Variation

  8. Q 4: Sometimes the smallest, or slowest animal in a herd is the one who doesn’t survive. What does this relate to according to Darwin?

  9. ANSWER: “Survival of the Fittest”

  10. Q 5: What is favorable about a lion’s color in the jungle?

  11. ANSWER: The color is a form of “camouflage” to help with survival

  12. Q 6: True OR False ~ Darwin believed that if organisms have the ability to adapt to their environment, these adaptations increase their chances of survival

  13. ANSWER: True ~ Darwin’s Theory of Natural Selection

  14. Q 7: We know that whales used to have hind limbs. What are these structures called? How is this possible?

  15. ANSWER: Vestigial Structures The ancestors of whales had hind limbs

  16. Q 8: Speciation is due to ______________

  17. ANSWER: Isolation

  18. Q 9: In the video clip of the study of the cliff swallows, their shortened wing adaptations is an example of ___________ ______________

  19. ANSWER: Artificial Selection

  20. Q 10: Characteristics that can be “seen”, such as hair color are referred to as _____________

  21. ANSWER: Phenotypes

  22. Q 11: What are the 4 Principles of Natural Selection?

  23. ANSWER: 1)Adaptation 2) Overproduction 3) Selection 4) Variation

  24. Q 12: Different colored eyes, different shaped fins…are examples of _____________

  25. ANSWER: Variation

  26. Q 13: Geographic Isolation can lead to ___________

  27. ANSWER: Speciation

  28. Q 14: Which phenotypes give giraffes advantages to survive in their environment?

  29. ANSWER: Long legs, long necks, long tongues

  30. Q 15: What is biodiversity?

  31. ANSWER: Biodiversity is a variety of life in a particular area , habitat, ecosystem or in the world

  32. Q 16: Organisms changing over time is ___________

  33. ANSWER: Evolution

  34. Q 17: These are similar structures, such as forelimbs, that come from common ancestors but have different functions

  35. ANSWER: Homologous Structures

  36. Q 18: These structures, such as wings, have similar functions due to the environmental demands within the habitat but do not come from a common ancestor.

  37. ANSWER: Analogous

  38. Q 19: This shows similar developmental stages amongst different species (kind of crazy how much we look like rabbits!! :0)

  39. ANSWER: Embryology

  40. Q 20: What was Darwin’s most noted evidence to support his Theory of Evolution?

  41. ANSWER: The different shaped beaks of the finches in the Galapagos Islands
