Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis questions require applying knowledge as well as higher level thinking skills.

Instructional Ideas

• Discuss other examples of the same mutation happening in different animal populations
  
• Review amino acids coding proteins in depth prior to the lesson

Classroom Considerations

• Relies on prior knowledge of evolution, mutation, gene flow, genetic drift, and natural selection

Pros

• Designed for Common Core standards, Next Generation Science Standards, AP® standards, and IB standards for biology
• Adapts easily from independent work to small group discussions
  

Cons

• None
