Amplify Evolution Vocabulary

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.
