Grade 9 Evolution
Sperm whales have vestigial hip bones, and a small percentage of sperm whales also have vestigial hind limbs. Which statement best explains the presence of these vestigial structures?
  1. Sperm whales evolved from ancestors that walked on land.
  2. Sperm whales are in the process of evolving into land mammals.
  3. These structures are acquired by each individual sperm whale during its lifetime.
  4. These structures resulted from sperm whales having a long period of embryonic development.
Grade 7 Evolution

Which is an example of a vestigial organ?
  1. legs of a horse
  2. fins of a fish
  3. arms of a monkey
  4. wings of an ostrich

Which statement about extinction is TRUE?
  1. Extinct organisms may be related to living organisms.
  2. Extinct organisms may be related to other extinct organisms.
  3. both a and b
  4. neither a or b
Grade 10 Evolution
Mechanisms of evolution include
  1. the gradualistic model and the punctuational model.
  2. adaptive radiation, co-evolution, convergent evolution, and divergent evolution.
  3. sympatric speciation and allopatric speciation.
  4. natural selection, mutations, genetic drift, and gene flow.

  1. morphology
  2. fossils
  3. DNA
  4. all of the above
Grade 7 Evolution
Why are black peppered moths less likely to be seen in the polluted city parks?
  1. Birds cannot see them as clearly on the dark tree bark.
  2. Birds prefer to eat white moths.
  3. Black peppered moths prefer sooty trees.
  4. White peppered moths prefer the countryside.
Grade 9 Evolution
New species can form in what type of evolution?
  1. Speciation
  2. divergent evolution
  3. convergent evolution
  4. None of the above.
Grade 9 Evolution
Many ancestral species have all evolved into similar looking species. How is this achieved?
  1. divergent evolution
  2. selective breeding
  3. convergent evolution
  4. Theory of Transmutation of Species
Grade 10 Evolution
The bird Darwin studied was the
  1. finch.
  2. mockingbird.
  3. cardinal.
  4. blue jay.
Grade 10 Evolution
How can temporal isolation lead to speciation?
  1. If two populations do not like each other, this may lead to the formation of a separate species.
  2. If two populations reproduce in different ways, this may lead them to become separate species.
  3. If two populations are separated by a geographic barrier, this will cause them to reproduce only with other members available, which may lead them to become separate species.
  4. If two populations reproduce at different times, they are unlikely to reproduce with each other, which may cause them to become separate species.
Grade 7 Evolution
What is a vestigial structure?
  1. old building
  2. body part that has lost its original function
  3. extra appendage
  4. mutated strand of DNA
Grade 7 Evolution
Early embryos of different vertebrates
  1. have acquired traits.
  2. have no similarities.
  3. have similarities.
  4. are called homologous embryos.
