  1. WASL!!!!! Take out one sheet of paper and your Peppered Moth Reading (yellow handout)

  2. 1. In what year was the first dark form of the peppered moth discovered? A) 1971 B) 1848 • 2003 • 1900

  3. 2. According to the map with pie charts indicating the distribution of light and dark forms of the moth, what percentage of the population in Dorset was the dark form? • 75% • 100% • 90% • 12%

  4. 3. A good explanation for 100% peppered-form moths in the far North of the United Kingdom is: A) Dark form moths did not have a chance to mutate. • The temperature in the North UK is colder. • There is little to no pollution in the far North of the UK. • Dark form moths hide better in the far North of the UK.

  5. 4. The data from Kettlewell’s experiments suggest that • Lichen are killed by pollution. • Dark trees are a good place for lichen to grow. • Moths eat lichen. • Predatory birds were one cause for the change in the moth population.

  6. 5. Natural selection states that • Individuals change their traits during their lifetime, and then pass these new traits on to their offspring. • Individuals with advantageous genes survive to reproduce and pass on these genes to their offspring. • Individuals change their genes and then pass these better genes on to their offspring. • Individuals are always mutating to get better.

  7. 6. List and describe the factors that led to the change in color of the moth population over time.
