What are the oldest fossils and why?

• B, C- because they are closest to the top

• A, B- because they are closest to the bottom

• They are all the same age- because they are all found on layer 2

• A, B- because they are found closest to the top

Fossil A is an ancient mollusk, an organism that needs water to survive. Why do you think that the mollusk went extinct in this particular sample of the fossil record?

• When the ocean levels rose in layer 4, the mollusk went extinct because they cannot live in water

• For some reason, the ocean disappeared causing the mollusk to thrive

• For some reason, the ocean disappeared causing the mollusk to go extinct

• When the ocean level rose in layer 4, the mollusk thrived because they need water

Homologous structures are bones or organs found in different animals which very closely resemble structures in different organisms. What can you conclude about the past of these organisms?

• They all have evolved through natural selection but do not use these structures anymore.

• They all share a common ancestor but have evolved through natural selection

• They all share a common ancestor but did not evolve from natural selection
