21. 50 points True, the Hardy-Weinberg principlesays that evolution will not occur in a population unless allelic frequencies are on by forces that cause change.

22. 10 points In terms of population size (large or small) and amount of mutations (few or many) Which combination would provide the greatest potential for evolution?

23. 10 points Having a small populationwith many mutations will provide the greatest potential for evolutionary change.

24. Bird wings and insect wings are examples of _____________ structures Bonus 10 points: do they have a common ancestor, yes or no? 20 points

25. Bird wings and insect wings are examples of Analogous structures Bonus 10 points: do they have a common ancestor, yes or no? NO common ancestor 20 points

26. 30 points Snake pelvis and human appendix are examples of __________ structure

27. 30 points Snake pelvis and human appendix are examples of vestigial structure

28. 40 points Bones of the bird wing, whale pectoral fin and reptile forelegs are examples of _________ structures Bonus 10 points: Do they show a common ancestor- Yes or no?

29. Bones of the bird wing, whale pectoral fin and reptile forelegs are examples of homologous structures Bonus 10 points: Do they show a common ancestor- Yes 40 points

30. Superficially similar features molded by natural selection in very different species would be classified as __________ structures. “Superficial” means that it only appears to be the same from the outside, but is totally different on the inside 50 points

31. Superficially similar features molded by natural selection in very different species would be classified as Analagous structures. “Superficial” means that it only appears to be the same from the outside, but is totally different on the inside 50 points

32. 10 points If Derived traits are recent, then _________ traits are more primitive

33. 10 points If derived traits are more recent, then ANCESTORAL traits are more primitive

34. 20 points If a population of organisms is in genetic equilibrium, then the _____________ principle is expressed.

35. If a population of organisms is in genetic equilibrium, then the HARDY-WEINBERG PRINCIPLE is expressed. 20 points

36. 30 points In general, if a population diverges and becomes reproductively isolated, then __________ has occurred.

37. In general, if a population diverges and becomes reproductively isolated, then SPECIATION has occurred 30 points

38. 40 points If no physical barrier separates a diverging population as it becomes two distinct populations, then _________ has occurred.

39. If no physical barrier separates a diverging population as it becomes two distinct populations, then Sympatric speciation has occurred. 30 Bonus points: NAME the other type of speciation and give an example… 40 points

40. If a species is suddenly introduced into a new habitat (Example: the cichlids that once lived in Africa’s Lake Victoria) then __________ might occur. 50 points

41. If a species is suddenly introduced into a new habitat (example: the cichlids that once lived in Africa’s Lake Victoria) then Adaptive Radiationmight occur. 50 points

42. 10 points Modified True/False: A mutation is a random change in genetic material

43. 10 points TRUE, A mutation is a random change in genetic material

44. 20 points Modified True/False Any change in the allelic frequencies in a population that is due to chance is called founder effect.

45. 20 points FALSE Any change in the allelic frequencies in a population that is due to chance is called Genetic drift

46. Modified True/False A population of ants declines to a very low number. When the ants’ habitat is turned into a park for picnics by humans, the population of ants rebounds. This is an example of natural selection. 30 points

47. False A population of ants declines to a very low number. When the ants’ habitat is turned into a park for picnics by humans, the population of ants rebounds. This is an example of bottleneck 30 points

48. Modified True/False Humans either born below-normal or above-normal birth weights have a lower chance of survival than those with average birth weights. Thus, human birth weights vary little. This is a form of natural selection called stabilizing selection. 40 points

49. true, Humans either born below-normal or above-normal birth weights have a lower chance of survival than those with average birth weights. Thus, human birth weights vary little. This is a form of natural selection called stabilizing selection. 40 points

50. Modified True/False Embryos of different organisms exhibit homologous structures during early development, but later become totally different structures in adult form. This indicates that the organisms evolved from different ancestors. 50 points
