What is survival of the fittest?

• It is where the fittest die out and therefore reproduce and pass on their genes
• It is where the fittest die out and therefore can't reproduce and pass on their genes
• It is where the fittest don't die out and therefore can't reproduce and pass on their genes
• It is where the fittest don't die out and therefore reproduce and pass on their genes

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct
  

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

What are the variations of mice in this environment?

• The white mice will go extinct.
• The grey mice will go extinct.
• All of the mice will grow longer fur.
• All of the mice will grow longer claws.
