homologous and analogous structures

An example of a homologous structure 

• human arm and bird wing
• rat appendix  and human appendix
• wing of butterfly and bird wing

An example of an analogous structure includes:

• wing of a butterfly and bird wing
• bird wing and human arm
• rat appendix and human appendix

Embryos of chickens, fish and humans look very similar. They all have folds known as gill pouches in the neck region. What may this suggest?

• they all formed in the ocean 
• they all evolved from a common ancestor
• they are all going extinct

  Notice the similarities of a shark and dolphin.  If these similarities developed by  common life experiences and not by common ancestry, which of the following vocabulary words would best describe them?

• a.  Vestigial Organ
•   b.  Embryological Similarities
• c.  Homologous Structures
• d.  Analogous 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 best definition for biological evolution is?

• A.  When Earth’s processes cause change overtime.
• B.  When rock’s change over time.
• C.  When a species changes      overtime.
