Analysis Questions 1.Are mutations always helpful? Explain. 2.How can mutations enable the evolution of a new species to occur? 3.Under ideal conditions, bacteria have a generation time of about 20 minutes. Humans have a generation time of about 20 years. Which would you expect to evolve faster?

Summary What did you think about the role mutations play in natural selection before this lesson? What did you learn about the role mutations play in natural selection from this lesson? (Minimum of 3 sentences!!!) What are some further thoughts or questions you have about how the role mutations play in natural selection?
