Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

  The diagram shows an image of a Pterosaur wing, bat wing, and bird wing.  These are all different organisms, but share similar wing structures.  If these structures are similar due to common ancestry, which of the following best describes them?

• a.  Vestigial Organ
• b.  Embryological Similarities
• c.  Homologous Structures
• d.  Analogous Structures

The bones of the forelimbs (wing or arm) of three animals are shown in the illustration. What is the most reasonable conclusion that can be drawn from a comparison of these structures?

• Birds and bats are closely related to each other while humans are unrelated to both

• The common ancestor of birds and bats must have had wings and flown.

• Humans live in habitats very different from the habitats of both birds and bats.

• Humans and bats share a closer evolutionary history with each other than with birds.
