Evidence for Evolution

A theory in science means...

• taking a limited amount of evidence and having a guess

• taking a large amount of evidence and finding the best scientific explanation

The theory that states that species of living things have changed over time:

• Similar embryos

• Correlation

• Superposition

• Evolution

The greater the similarity of DNA between two different species...

• the closer in time they had a common ancestor

• the further back in time they had a common ancestor

• the less likely they are to have had a common ancestor
