When investigating an area that has sedimentary rock, you find two fossils.  The first fossil was found in a layer of rock about 2 meters above the second fossil.  From this information you can infer

• the second fossil was unlikely to be from the Precambrian

• the first fossil is younger than the second fossil.

• the second fossil is younger than the first fossil.

• both fossils are likely to have been from aquatic organisms.

• both fossils are likely the same species.

Protists do not form a monophyletic group. A good explanation of why that statement is true would be that the group that contains all protists

• and their most recent common ancestor must include taxa that are not protists.

• does not have a common ancestor.

  
  

• does not include prokaryotes.

  
  

• is not big enough to call the group a Kingdom.

  
  

• would only be monophyletic if it included plants.
