
Hold up a number! 
Practice: What types of variations
do you see in the first picture?
What “selection” is going on?
Who is “most fit”?
An overview of natural selection
Mouse Lab Wrap-Up

How did this lab show natural selection?
 What were the variations?
 What was the “selection”?
 Who was fit? Unfit?
 What change did you see in the population?
