Charles Darwin Quizzes & Trivia

Test Your Knowledge About Darwin's Theory Of Natural Selection! The environment we live in changes due to many factors, and for living things to survive, they need to change with the environment. Do you think you know enough about the theory put forth by Darwin on the changes? How about you refresh your memory by taking this test?

Questions and Answers
  • 1. 
    Charles Darwin was a(n) _______________ , a person who studies plants and animals by observing them.
  • 2. 
    Darwin was not the first to develop a theory of _______________, but his theory is the one best supported by evidence today.
  • 3. 
    The type of tortoise, mockingbird, and finch that live on each of the Galápagos Islands was slightly different; Darwin later figured out that some varieties were different enough to be classified as different _______________.
  • 4. 
    Darwin noticed that there was a relationship between each _______________ and the food sources of the island it lived on.
  • 5. 
    The species of tortoise that lived on an island with tall cacti had _______________ necks; the species of tortoise that lived on an island with lots of short grass had short necks.
  • 6. 
    Darwin thought all the Galápagos tortoises shared a common _______________ that came to one of the islands millions of years ago.
  • 7. 
    Darwin knew that in any species, members of the same species each have slight differences, called _______________ .
  • 8. 
    Darwin didn’t know about _______________, but he realized that variations in populations could help explain how the different species of Galápagos tortoises and other organisms evolved.
  • 9. 
    Darwin knew that food is a(n) _______________ resource, so members of a species that live in the same area compete for food.
  • 10. 
    If a variation benefited a tortoise, allowing it to compete for food better than other tortoises, the tortoise lived longer, reproduced more, and passed on its variations to its _______________.
  • 11. 
    _______________ _______________ is the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than populations that do not have the variations.
  • 12. 
    A(n) _______________ is a characteristic of a species that enables the species to survive in its environment.
  • 13. 
    Scientists classify adaptations into _______________ categories.
  • 14. 
    _______________ adaptations involve shape, size, color, and other physical features; the length of a Galápagos tortoise species’ neck is an example of this type of adaptation.
  • 15. 
    _______________ adaptations involve the way organisms act; hunting at night is an example of this type of adaptation.
  • 16. 
    _______________ adaptations involve internal body systems that affect organisms’ biochemistry; expanding blood vessels that cool a jackrabbit’s blood is an example of this type of adaptation.
  • 17. 
    A structural adaptation that aids members of a species in blending in with their environment is called _______________ .
  • 18. 
    An adaptation in which one species resembles another species is called _______________ 
  • 19. 
    The living and the nonliving parts of the _______________ are always changing; species that cannot adapt to such changes will become extinct.
  • 20. 
    Darwin’s theory of evolution by _______________ _______________ predicts that species will develop adaptations and, therefore, eventually closely match Earth’s changing environments.
  • 21. 
    _______________ _______________ is the breeding of organisms for desired characteristics.
  • 22. 
    Darwin realized that _______________ _______________ and selective breeding are similar processes.
  • 23. 
    In natural selection, nature causes the changes in the species; in _______________ _______________ , humans cause the changes in the species.
  • 24. 
    For this reason, Darwin called selective breeding _______________ selection.
  • 25. 
    _______________ _______________ explains and supports Darwin’s theory.
