Questions and Answers

What type of evidence for evolution is provided by vestigial structures?

  • They support the theory of punctuated equilibrium
  • They demonstrate convergent evolution
  • They indicate common ancestry and evolutionary change (correct)
  • They show rapid adaptation to the environment

Which concept did Darwin derive from Malthus' work?

  • Neutral evolution
  • Genetic drift
  • Survival of the fittest (correct)
  • Punctuated equilibrium

What is a transitional form in the context of evolution?

  • An organism with features intermediate between its ancestors and descendants (correct)
  • An extinct species with no living descendants
  • A species that has not changed over time
  • A species that originated from hybridization
