Principles of Natural Selection
Make the following Foldable to help you understand the process of natural selection.

30. Fold a sheet of paper in half lengthwise.
Foldables
Fold a sheet of paper in half lengthwise.

31. Foldables
Fold paper down 2.5 cm from the top. (Hint: From the tip of your index finger to your middle knuckle is about 2.5 cm.

32. Foldables
Open and draw lines along the 2.5-cm fold and the center fold. Label as shown.

33. Foldables
Summarize in a Table
As you read, list the five principles of natural selection in the left-hand column. In the right-hand column, briefly write an example for each principle.

34. Reviewing Main Ideas 1
Ideas About Evolution
Evolution is one of the central ideas of biology. It explains how living things have changed in the past and is a basis for predicting how they might change in the future.
Charles Darwin developed the theory of evolution by natural selection to explain how evolutionary changes account for the diversity of organisms on Earth.

35. Reviewing Main Ideas 1
Ideas About Evolution
Natural selection includes concepts of variation, overproduction, and competition.
According to natural selection, organisms with traits best suited to their environment are more likely to survive and reproduce.

36. Clues About Evolution 2 Fossils provide evidence for evolution.
Reviewing Main Ideas 2
Clues About Evolution
Fossils provide evidence for evolution.
Relative dating and radiometric dating can be used to estimate the age of fossils.
The evolution of antibiotic-resistant bacteria, pesticide-resistant insects, and rapid genetic changes in plant species provides direct evidence that evolution occurs.
Homologous structures, vestigial structures, comparative embryology, and similarities in DNA provide indirect evidence of evolution.

37. The Evolution of Primates
Reviewing Main Ideas 3
The Evolution of Primates
Primates include monkeys, apes, and humans. Hominids are humanlike primates.
The earliest known hominid fossil is Australopithecus.
Homo sapiens are thought to have evolved from Cro-Magnon humans about 400,000 years ago.

38. Chapter Review
Question 1
Charles Darwin observed that the beak shape of each species of finch is related to its eating habits. Which beak would best be used for probing beneath tree bark?
A. long, slender
B. long, fat
C. medium-sized
D. short, strong
LE 3.1

39. Chapter Review
Answer
The answer is A. A long, slender beak would be best for probing beneath tree bark.

40. Question 2 What would a short, strong beak be best used for?
Chapter Review
Question 2
What would a short, strong beak be best used for?
A. eating insects
B. drinking nectar
C. prying insects out of small holes
D. breaking hard shells
LE 3.1

41. Chapter Review
Answer
The answer is D. Finches that eat nuts and seeds have short, stout, “crushing” beaks.

42. Chapter Review
Question 3
A _______ is an inherited trait that makes an individual different from other members of its species.
Answer
The answer is variation. Variations result from permanent changes, or mutations, in an organism’s genes.
LE 3.1

43. Chapter Review
Question 4
_______ are scientists who study the past by collecting and examining fossils.
A. Biologists
B. Entomologists
C. Ecologists
D. Paleontologists
LE 3.2b

44. Chapter Review
Answer
The answer is D. Paleontologists study fossils in order to learn which plants and animals lived during various periods of Earth’s history.

45. Chapter Review
Question 5
_______ and _______ are two basic methods used to estimate the ages of rocks and fossils?
LE 3.2b

46. Chapter Review
Answer
The answer is relative dating and radiometric dating. Relative dating is based on rock layers and radiometric dating compares the amount of radioactive element with the amount of nonradioactive element in the rock.

Question 1
Which is an imprint on sediment that later hardens to become rock?
A. cast fossil
B. frozen fossil
C. imprint fossil
D. mineralized fossil
LE 3.2c

48. Standardized Test Practice
Answer
The answer is C. A leaf, feather, bones, or even the entire body of an organism can leave an imprint on sediment that later hardens to become rock.

49. Question 2 Which is NOT an example of an adaptation? A. albinism
Standardized Test Practice
Question 2
Which is NOT an example of an adaptation?
A. albinism
B. camouflage
C. hibernation
D. nocturnal behavior
LE 3.1

50. Standardized Test Practice
Answer
The answer is A. An adaptation is any variation that makes an organism better suited to its environment. Albinism prevents an organism from blending into its environment.

51. Question 3 Which is the best example of punctuated equilibrium?
Standardized Test Practice
Question 3
Which is the best example of punctuated equilibrium?
A. alligator evolution
B. camel evolution
C. human evolution
D. penicillin-resistant bacteria
LE 3.1b

52. Standardized Test Practice
Answer
The answer is D. According to the punctuated equilibrium model, rapid evolution comes about when the mutation of a few genes results in the appearance of a new species over a relatively short period of time.

53. Standardized Test Practice
Question 4
According to the Principles of Natural Selection, which of the following is the best answer?
LE 3.1

54. Organisms produce just enough offspring to survive.
Standardized Test Practice
Organisms produce
just enough offspring
to survive.
B. All variations are
helpful.
LE 3.1

55. C. Organisms with traits best suited to their environment are more
Standardized Test Practice
C. Organisms with traits
best suited to their
environment are more
likely to survive.
D. Variations are never
passed to offspring.
LE 3.1

56. Standardized Test Practice
Answer
The answer is C. Organisms produce more offspring that can survive, not all variations are helpful, and some variations are passed to offspring.

57. Standardized Test Practice
Question 5

B. hominids
C. sedimentary
D. vestigial
LE 3.1

58. Standardized Test Practice
Answer
