  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.

Grade 7 Evolution
Early embryos of different vertebrates
  1. have acquired traits.
  2. have no similarities.
  3. have similarities.
  4. are called homologous embryos.
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
Individuals within a population have slightly different traits, or variations. How do variations improve the likelihood that a population will survive?
  1. Variation enables individuals to produce offspring that will survive into adulthood.
  2. Variation enables the population to create new genes, which help individuals survive a significant change in their environment.
  3. Variation provides the raw material upon which natural selection acts in a population.
  4. Variation enables individuals who are very different from the rest of the population to reproduce more successfully.
Grade 7 Evolution
Geography plays a role in evolution.
  1. True
  2. False
Grade 7 Evolution
Structures that do not seem to have a function are called
  1. irrelevant structures.
  2. homogeneous structures.
  3. vestigial structures.
  4. heterogeneous structures.
Grade 7 Evolution
The core idea of evolutionary "success" is oriented around
  1. intelligence.
  2. reproduction.
  3. lifespan.
  4. water.
Grade 7 Evolution
Darwin's ship was the HMS Bulldog.
  1. True
  2. False
Grade 7 Evolution
                is the evolutionary history of an organism.
  1. Evolution
  2. Creation
  3. Phylogeny
  4. Biology
Grade 7 Evolution
A scientist is studying the DNA of three species. Species A and species B have DNA that is 97% similar. Species C and species A have DNA that is 95% similar. What can the scientist conclude?
  1. Species B is equally related to both species A and species C.
  2. Species B has a closer evolutionary relationship with species C than it does with species A.
  3. Species A has a closer evolutionary relationship with species B than it does with species C.
  4. Species A has a closer evolutionary relationship with species C than it does with species B.
Grade 7 Evolution
Which statement best describes the tiny leg bones that some whales have, which do not aid in their movement or serve any other function?
  1. The structures grow and improve in function as they are used.
  2. The structures function at certain times of the year or under certain conditions.
  3. The structures will become adaptations when the environment changes.
  4. The structures have lost all or most of their function over evolutionary time.
Grade 7 Evolution
Why did white peppered moths change to black peppered moths in the cities?
  1. The sun tanned the moths and made them dark.
  2. The moths mated with other dark moths.
  3. The Industrial Revolution created pollution that made the white birch trees dark.
  4. The dark peppered moths are a different species.
Grade 7 Evolution
Which is not a piece of evidence that supports evolution?
  1. vestigial structures
  2. chromosomal structure
  3. homologous structures
  4. fossil record
  5. embryology
Grade 7 Evolution
A frog may have hundreds of offspring at a time, but only a small number will survive. This is an example of
  1. adaptation.
  2. overproduction.
  3. artificial selection.
  4. genetic variation.
