Evolutionary Relationships

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.
