Evidence for Evolution

1. 
Which of the following does NOT support Darwin's theory of evolution?
  1. fossil record
  2. homologous structures
  3. similarities in embryos
  4. differences in plants
2. 
Two different organisms have anatomically similar structures that are believed to have originated from a common ancestor. The functions of the structures are different as a result of the environments in which the organisms live. These anatomically similar structures are
  1. vestigial
  2. homologous
  3. tropisms
  4. mutations
  5. none of the above
3. 
In forming his theory of evolution, of what did Darwin mostly lack an adequate understanding?
  1. geology
  2. heredity
  3. anatomy
  4. geography
4. 
What are remnants of organs that were better developed and more functional in the ancestors of a species and now serve little or no purpose, such as the pelvis in some whales and snakes, called?
  1. remainder organs
  2. vestigial organs
  3. homologous structures
  4. analogous structures
5. 
One of Charles Darwin's most commonly known species that he observed and studied while on the Galapagos Islands were finches. How did these finches arrive in the Galapagos Islands?
  1. They were left there by previous travelers
  2. They spontaneously generated once food sources were available
  3. They flew, or were blown, from South America
  4. Darwin brought them with him from other places he visited before
6. 
The picture shows examples of the different beak types Darwin observed on the finches of the Galapagos Islands. How does this structure provide evidence for evolution?
Darwin's Finches






7. 
Which of these pairs indicates an example of a homologous structure?
  1. the tail of a cheetah and the tail of a dog
  2. the wing of a bat and the wing of a bird
  3. the fluke of a whale and a hand of a human
  4. the ears of an elephant and the scales of a dinosaur
8. 
The long beak of a hummingbird is specially adapted to fit into particular flowers in order to get the nectar that is deep within the petals. Only certain birds can feed on these flowers and the flowers can only be pollinated by certain species of birds. This relationship indicates these species have undergone                             .
9. 
How have sharks and dolphins been affected by convergent evolution?



10. 
How does having a common embryology serve as evidence for evolution?
