Questions and Answers

According to Lamarck's hypothesis of evolution, species evolve through which mechanisms?

  • Natural selection and genetic mutation
  • Use and disuse of body parts and inheritance of acquired characteristics (correct)
  • Competition for resources and survival of the fittest
  • Random genetic drift and gene flow

Which statement best describes Lamarck's hypothesis of evolution?

  • Species evolve through the competition for resources and survival of the fittest
  • Species evolve through natural selection and genetic mutation
  • Species evolve through the use and disuse of body parts and the inheritance of acquired characteristics (correct)
  • Species evolve through random genetic drift and gene flow

What is the main difference between Lamarck's hypothesis and the mechanisms proposed by Darwin?

  • Lamarck's hypothesis focuses on natural selection, while Darwin's mechanisms focus on genetic mutation
  • Lamarck's hypothesis includes the inheritance of acquired characteristics, while Darwin's mechanisms do not (correct)
  • Lamarck's hypothesis is supported by evidence, while Darwin's mechanisms are not
  • Lamarck's hypothesis involves the use and disuse of body parts, while Darwin's mechanisms involve competition for resources
