This fossil snake and this living rat both have a structure in their skull called the quadrate bone. How did this happen?

• The snake and rat are different species, so they are related. They inherited the quadrate bone structure from separate ancestors.

• ll species have their own specific body structures, so it is just a coincidence.

• The snake and rat both share the same ancestor population that had a quadrate bone.

• It is impossible to say. Fossils are very old.

This octopus and this surf clam both have a body structure called a mantle, which covers their soft bodies. However, the octopus’s mantle has muscles that help the octopus swim. The surf clam’s mantle helps the clam build its shell. Why are the mantles different?

• All species have their own specific body structures, so it is just a coincidence

• The octopus and surf clam are different species, so they do not share an ancestor population.

• It is impossible to explain the body structures of different species

• The octopus and surf clam both inherited the mantle structure from a shared ancestor population.

What is a common method used to amplify DNA sequences to study evolutionary history?

• Polymerase Chain Reaction (PCR)

• Gel Electrophoresis

• X-ray Crystallography

• Mass Spectrometry

How does the study of evolutionary history benefit from the amplification of ancient DNA?

• It allows for the reconstruction of extinct species' genomes

• It speeds up the process of natural selection

• It helps in the creation of genetically modified organisms

• It provides a method for cloning ancient species
