You are presented with the quiz "Fossils show what over geologic time above the level of the species?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "macroevolution is evolution over geologic time above the level of the species" and "sometimes, an isolated fossil is held up as evidence of macroevolution". 

So, what's the best answer to the question?


 

     evolution
