• a gradual change in a species over time 

Which statement is true?

• Species with similar evolutionary histories are not classified together 
• Species with different evolutionary histories are classified more closely together 
• Species with similar evolutionary histories are classified more closely together 
• Species with similar evolutionary histories are classified in the same species 

To determine whether two organisms are related, scientist may compare the ______ of their cells 

• size and structure 
• nuclei
