  • 6. 
    A characteristic that an organism exhibits during its lifetime will only affect the evolution of its species if the characteristic
    • A. 

      Results from isolation of the organism from the rest of the population

    • B. 

      Is due to a genetic code that is present in the gametes of the organism

    A species of bird known as Bird of Paradise has been observed in the jungles of New Guinea. The males shake their bodies and sometimes hang upside down to show off their bright colors and long feathers to attract females. Females usually mate with the "flashiest" males. These observations can be used to support the concept that
    • A. 

      Unusual courtship behaviors lead to extinction

    • B. 

      Some organisms are better adapted for asexual reproduction

    • C. 

      Homeostasis in an organism is influenced by physical characteristics

    • D. 

      Behaviors that lead to reproductive success have evolved

  • 8. 
    Which statement provides evidence that evolution is still occurring at the present time?
    • A. 

      The extinction rate of species has decreased in the last 50 years.

    • B. 

      Many bird species and some butterfly species make annual migrations.

    • C. 

      New varieties of plant species appear more frequently in regions undergoing climatic change.

    • D. 

      Through cloning, the genetic makeup of organisms can be predicted.

  • 9. 
    The diagram below represents possible evolutionary relationships between groups of organisms. Which statement is a valid conclusion that can be drawn from the diagram?
    • A. 

      Snails appeared on Earth before corals.

    • B. 

      Sponges were the last new species to appear on Earth.

    • C. 

      Earthworms and sea stars have a common ancestor.

    • D. 

      Insects are more complex than mammals.

  • 10. 
    Which statement concerning the evolution of species A, B, C, D, and E is supported by the diagram below?
    • A. 

      Species B and C can be found in today's environments.

    • B. 

      Species A and D evolved from E.

      Species A and C can still interbreed.

    • D. 

      Species A, B, and E all evolved from a common ancestor and all are successful today.

  • 11. 
    For centuries, certain animals have been crossed to produce offspring that have desirable qualities. Dogs have been mated to produce Labradors, beagles, and poodles. All of these dogs look and behave very differently from one another. This technique of producing organisms with specific qualities is known as
    • A. 

      Gene replication

    • B. 

      Natural selection

    • C. 

      Random mutation

    • D. 

      Selective breeding

  • 12. 
    The differences observed in the bird beaks are most likely due to
    • A. 

      Asexual reproduction of these finch species

    • B. 

      The selection for different shaped beaks that best suit different niches

    • C. 

      The genetic recombination associated with mitotic cell division

    • D. 

      The genetic engineering of the DNA of each of these species

  • 13.

      The lack of mutations resulted in the protective coloration.
