What are the components of Darwin's Theory of Evolution?

• Organisms change over time, evolution is rapid, and all organisms have unique ancestors

• Organisms remain constant over time, evolution is slow, and all organisms have common ancestors

• Organisms change over time, evolution is slow, and all organisms have common ancestors

• Organisms change over time, evolution is quick, and organisms have no ancestors

What is a common ancestor according to Darwin's theory?

• An individual organism that is the source of all genetic variation

• A mythical creature that represents the beginning of life

What is the significance of genetic similarities in DNA among different species?

• They indicate that all species have identical DNA

• They suggest that species with similar DNA are more distantly related

• They suggest that species with similar DNA are more closely related

• They show that DNA is not important in evolution
