A vs. 6. Compare the histograms of the average for the parents and their offspring on Daphne Major in 1976. Is there any evidence of directional selection? Explain. C vs. D 7. Compare the histograms of the surviving finches on Daphne Major in 1978 with the histogram of the offspring finches on Daphne Major in 1976. Is there any evidence of selective pressure? Explain. 8. The two populations of finches (from Daphne Major and Santa Cruz) haven't yet evolved into new species. How might hybrids produced from parents from the two different islands affect the results of this activity? Explain. 9. Write a summary paragraph of your findings from this investigation.
