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

In which layer did fossil C come into existence? How do you know this?

• Layer 1-Because that is the layer it is first seen

• Layer 1- Because that is the last layer it is seen in

• Layer 2- Because that is the layer it is first seen

Do no rush, examine the diagram. How has life evolved starting with the oldest fossils?

• Life started in the ocean and over time organism became to appear with no common ancestors. Fish evolved first, then reptiles, then mammals and finally birds.

• Life started in the ocean then slowly evolved through natural selection to life on land. Fish evolved first, then reptiles, then mammals and finally birds.

• Life started on land and over time humans began to evolve into fish, then reptiles, and birds.

• Life started in the ocean as four-legged amphibians which then evolved to palm trees, then to dinosaurs, and eventually into humans.

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
