  2. Part 1: Choosing the Most Fit Answer

  3. Choose the most fit answer In order for evolution to occur, what must happen in a population? • genetic drift • natural selection • geographicisolation • reproductive isolation

  4. B

  5. Choose the most fit answer What does the line graph show? • Populations increase at a constant rate in ecosystems. • Populations usually increase rapidly and then level off. c. Populations increase at an exponential rate. • Ecosystems are able to support any number of populations.

  6. B

  7. Choose the most fit answer Within a decade of the introduction of a new insecticide, nearly all of the descendants of the target pests were immune to the usual-sized dose. The most likely explanation for this immunity to the insecticide is that ____. a. eating the insecticide caused the insects to become resistant to it b. eating the insecticide caused the insects to become less resistant to it c. it destroyed organisms that cause disease in the insects, thus allowing them to live longer d. it selected random mutations that were present in the insect population and that provided immunity to the insecticide

  8. D

  9. Choose the most fit answer Natural selection can BEST be defined as the ____. a. survival of the biggest and strongest organisms in a population b. elimination of the smallest organisms by the biggest organisms c. survival and reproduction of the organisms that occupy the largest area d. survival and reproduction of the organisms that are genetically best adapted to the environment

  10. D

  11. Choose the most fit answer Which of the following was NOT part of Darwin’s original Theory? a. There is overpopulation in nature. b. There is variation in the individuals of the population. c. Variations are caused by mutations. d. There is natural selection.

  12. C

  13. Choose the most fit answer By the end of Darwin’s trip, he concluded that ____. a. evolution occurs rapidly on the Galapagos Islands b. change in life forms occurs only on islands c. life forms can and do change d. Galapagos Islands organisms are also found in Tahiti and the Cocos Islands

  14. C

  15. Choose the most fit answer Ancestors of the koala lived on the ground, but modern koalas live in trees and eat eucalyptus leaves, which are poisonous to most other animals. The difference between the ancestor and modern koalas was caused by • the presence of homologous structures • selective breeding • the presence of vestigial organs • natural selection

  16. Choose the most fit answer Fossils of Archaeopteryx show that this animal had feathers, like a bird. It also had a bony tail, teeth, and claws on its wings, like a reptile. These fossils are evidence that support the idea that • birds and reptiles have a common ancestor • reptile species are more advanced than bird species • birds have changed very little over millions of years • reptiles are warm-blooded like birds

  17. Choose the most fit answer Some viral diseases require only one vaccination, which lasts for years. For other diseases such as the flu, vaccinations last only one season. The flu vaccine lasts such a short time because the flu virus • is more easily transmitted than other viruses • is less dangerous than other viruses • mutates much more rapidly than other viruses • is much smaller than other viruses

  18. Choose the most fit answer Which of the following is considered by most biologists to be the most accurate in supporting the theory of evolution? a. fossils c. DNA sequencing b. embryology d. genetic equilibrium

  19. Choose the most fit answer There are currently millions of species of organisms and new species are still being discovered. Based on Darwin’s theory of evolution, which of the following best describes how millions of species have developed? • Organisms passed on acquired characteristics to evolve from lower life forms to higher life forms. • Completely different species crossed with one another to form the many different organisms. • Organisms were selectively bred to create different species. • Different genetic variations in organisms were selected in different environments.

  20. Choose the most fit answer Which of the following best supports the idea that organisms and environments have changed over time? • the discovery of fossilized fern plants in Antarctica • the many different species of plants in tropical areas • the production of sterile hybrid animals such as the mule • the ability of many animals to learn new behaviors

  21. Choose the most fit answer The cotton whitefly has become a key pest for farmers, damaging many kinds of crops. The cotton whitefly has developed resistance to a variety of pesticides. Pesticide resistance would most likely develop in insects that • reproduce rapidly • undergo complete metamorphosis • feed on few types of plants • live in very limited regions

  22. Choose the most fit answer The DNA of an organism contains information that is used to sequence amino acids to form specific proteins. The existence of different organisms with very similar amino acid sequences is evidence of • a common ancestor • a similar diet • common adaptive behaviors • a similar environment

  23. Choose the most fit answer This diagram represents the bone structures of the front limbs of four different animals. What do the similarities of the structures suggest about these organisms? • They grow at the same rate. • They live for the same length of time. • They live in the same environment. • They evolved from a common ancestor.

  24. Choose the most fit answer What advantage do sexually reproducing organisms have over asexually reproducing organisms? • genetic variation • increased fertilization rate • genetic stability • increase reproductive rate

  25. Choose the most fit answer Genetic equilibrium exists in a population that is stable. Which conditions would support genetic equilibrium within a species? • frequent mutations • small number of individuals • random mating • migration into the population

  26. Part 2: Finding Connections

  27. Finding Connections What 2 macromolecules are found in ALL living organisms that allow for the continuity of life?

  28. Finding Connections Explain what the word fitness means as it pertains to natural selection.

  29. Finding Connections Is it ok to say that a scientific theory is just a theory? ( YES / NO ) Explain the difference between a scientific theory and the venacular use of the term theory.

  30. Finding Connections • Genetic Drift • Gene Flow • Non-random mating • Mutations • Natural Selection • Speciation • Gradualism • Punctuated Equilibrium • Adaptive Radiation • Convergent evolution • Coevolution • Extinction

  31. Finding Connections • Genetic Drift • Gene Flow • Non-random mating • Mutations • Natural Selection • Speciation • Gradualism • Punctuated Equilibrium • Adaptive Radiation • Convergent evolution • Coevolution • Extinction
