Questions and Answers

What was the main reason for the increase in frequency of dark-colored moths during the industrial revolution?

  • Decreased pollution causing light-colored moths to die off.
  • Increased pollution resulting in more dark-colored moths surviving due to camouflage. (correct)
  • Light-colored moths adapting to become dark-colored.
  • Genetic mutation changing light-colored moths to dark-colored moths.

What caused the increase in frequency of dark moths in the population?

  • Decrease in the number of light-colored moths.
  • A sudden mutation making all moths dark.
  • Alteration in the gene pool of the moth population. (correct)
  • Accelerated evolution changing light moths to dark.

Which concept suggests that species' characteristics are relatively stable but may lead to rapid changes resulting in the development of new species?

  • Gradualism
  • Darwinism
  • Punctuated equilibrium (correct)
  • Mutationism
