Questions and Answers

What is the main idea behind the theory of evolution?

  • Species evolve suddenly without any relation to each other
  • Species are fixed and unchanging over time
  • All species are unrelated
  • Species are related and gradually change over time (correct)
  • What type of changes do mutations cause in DNA?

  • Temporary changes in the gene sequence
  • Permanent changes in the gene sequence (correct)
  • Observable phenotypic changes
  • Changes that only affect behavior
  • Which mechanism of evolution involves changes in the frequency of genotypes in a population?

  • Genetic Drift
  • Non-Random Mating
  • Gene flow (correct)
  • Natural Selection
