1. SBI3U Evolution Test Review--School Reach Questions

2. # Question Answer

3. 1 A scientific statement must be able to be this? Falsifiable (proven false)

4. 2 How do the fossils found deeper in the rocks compare with respect to complexity and age? Less complex and older

5. 3 What is the study of fossils called? Paleontology

6. 4 If a cat has 21 differences in DNA in a protein when compared to a human and a dog has 12 differences, which is more closely related to humans? dog

7. 5 A group of islands are near the coast of a continent. Which of the group would be inhabited the longest? Closest island to the mainland

8. Name one teacher who is retiring from Nelson this year?

9. 6 How does embryology provide evidence for evolution? More similar the embryos the more closely related

10. 7 What did Thomas Malthus contribute to Darwin’s theory Populations grow exponentially if no stress put upon them

11. 8 What is a species? Populations that can interbreed and have fertile offspring

12. 9 A change in the allele frequencies in a population describes which term? Microevolution (accept evolution)

13. 10 How old is the earth? (within 500 million years) 4.54 billion years old

14. 11 If two species that are not related develop similar structures as they are adapting to similar environments (such as streamlined bodies in fish and mammals), what type of evolution is occurring? Convergent evolution

15. 12 If flowers have differing flowering times so they don’t interbreed, which type of reproductive isolating mechanism is this referring to? Temporal

16. 13 What does the term ‘fit’ refer to in “survival of the fittest”? How many offspring are produced

17. What is Nelson’s High School Mascot?

18. 14 A rapid population decrease refers to what term? Bottleneck

19. 15 What happens to diversity of a population after a bottleneck? Decreases

20. 16 What is the movement of alleles from one population to another? migration

21. 17 What is the primary drive of evolution…what changes? The environment

22. 18 Competition is needed for evolution to occur. Name 3 things that organisms could be competing for. Food, shelter, mates, sunlight, space, water

23. 19 Give an example of homologous structures and define the term Structures that came from a common ancestor but are adapted for different environments

24. 20 What type of evolution results in homologous structures? Divergent evolution

25. 21 Name the process that describes how life arises spontaneously. Abiogenesis

26. 22 Name one of the scientists who coined the term “punctuated equilibrium” Stephan Jay Gould and Niles Eldredge (name one)

27. 23 What is a vestigial structure? Structure that had a function in the past but no longer

28. Name the famous artist that has original art (not prints) in the front office and constructed the mural half way up the stairs from the office? Robert Bateman

29. 24 Name the type of speciation where the populations live in the same habitat but become reproductively isolated such that they can no longer interbreed successfully. Sympatric speciation

30. 25 In allopatric speciation, what is needed to separate the species (or give an example) Geographic barrier such as a mountain, river etc.

31. 26 A giraffe’s neck gradually got longer over several generations of competing for food high in the trees. Name the type of selection. Directional selection

32. 27 Name the type of selection which can result in speciation. Disruptive selection

33. 28 If a population is in Hardy-Weinberg equilibrium, what does this mean in evolutionary terms? It is not evolving.

34. 29 What are the 5 requirements for Hardy-Weinberg equilibrium? NMMR +

35. 30 Name the type of selection where humans select traits to produce new breeds. Artificial selection

36. 31 State a disadvantage of artificial selection. Reduces genetic variability

37. 32 When a few members of a population leave and form their own population thereby reducing the genetic diversity of the original population. Founder effect

38. For which famous battle did Lord Horatio Nelson lead in 1805? Battle of Trafalgar

39. 33 Founder effect and bottleneck effect are both examples of genetic drift. What’s the difference? Bottleneck results from a natural disaster or human interference

40. 34 Define genetic drift Changes in allele frequencies of a gene pool due to chance events.

41. 35 Theory that eukaryotes evolved from the ingestion of a prokaryote by another bacterium Endosymbiosis theory

42. 36 What is significant about the framed written letter written by Lord Nelson that is in the front office? Written by the hand that he lost in battle so it was written prior to that

43. 37 Name the type of selection that favours one extreme. Directional

44. 38 Courtship displays are an example of this type of selection. Sexual

45. 39 Evolution in which similar traits arise in unrelated species due to similar environmental selection pressures. Convergent evolution

46. 40 A change in the gene pool due to random chance Genetic drift

47. 41 What is the only source of new genes? mutation

48. 42 On which molecule can a mutation take place? DNA

49. 43 In a polluted environment, would dark or light moths be in greater numbers? Dark

50. 44 If one species copies another species in appearance or behaviour, what term does this describe? Mimicry
