Types of Evolutionary Relationship

Which best describes how shared characteristics can be used to identify evolutionary relationships?

• If organisms have a common ancestor, most of their characteristics will be shared.

• If two organisms have a shared characteristic, it means one evolved from the other.

• If organisms have many shared characteristics, they are likely to be closely related.

• If organisms have a shared characteristic, it means they are closely related.

Which statements best describe shared characteristics? Select two options.

• Shared characteristics always exist in the common ancestor and in the modern organism.

Which best describes the two types of shared characteristics?

• 1 - characteristics that remain in the common ancestor and the modern organism

  2 - characteristics that are new and have been modified from what was found in the common ancestor

• 1 - characteristics that are new in the common ancestor and the modern organism

  2 - characteristics that have been modified from what was found in the common ancestor
