Questions and Answers
  • 1. 
    The evolutionary pathways of five species are represented in the diagram below. Which statement is supported by the diagram?
    • A. 

      Species C is the ancestor of species B.

    • B. 

      Species D and E evolved from species B.

    • C. 

      Species X evolved later than species D but before species B.

    • D. 

      Both species C and species D are related to species X.

  • 2. 
    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.

  • 3. 
    To determine evolutionary relationships between organisms, a comparison would most likely be made between all of the characteristics below except
    • A. 

      Methods of reproduction

    • B. 

      Number of their ATP molecules

    • C. 

      Sequences in their DNA molecules

    • D. 

      Structure of protein molecules present

  • 4. 
    Which observation could best be used to indicate an evolutionary relationship between two species?
    • A. 

      They have similar base sequences.

    • B. 

      They have similar fur color.

    • C. 

      They inhabit the same geographic regions.

    • D. 

      They occupy the same niche.

  • 5. 
    Some evolutionary pathways are represented in the diagram below. An inference that can be made from information in the diagram is that
    • A. 

      Many of the descendants of organism B became extinct

    • B. 

      Organism B was probably much larger than any of the other organisms represented

    • C. 

      Most of the descendants of organism B successfully adapted to their environment and have survived to the present time

    • D. 

      The letters above organism B represent members of a single large population with much biodiversity

  • 6. 
    An evolutionary pathway is represented below. Which statement about evolutionary pathways is most accurate
    • A. 

      All evolutionary pathways show that life began with autotrophic organisms that soon evolved into heterotrophic organisms.

    • B. 

      Two organisms on the same branch of an evolutionary pathway are more closely related to each other than to those on distant branches.

    • C. 

      All the organisms shown at the ends of evolutionary pathway branch tips are alive today.

    • D. 

      Evolutionary pathways show that evolution is a short-term process.

  • 7. 
    • A. 

      Evolution always results in favorable traits.

    • B. 

      Evolution does not always result in a species that will survive to present time.

    • C. 

      Evolution leads to less complex organisms.

    • D. 

      Evolution results in the same changes in all species.

  • 8. 
    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.

    • C. 

      Species A and C can still interbreed.

    • D. 

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