If so, which one? One the same x- and y-axes, plot three line graphs representing the success of each beak variation throughout the six rounds. Plot rounds 1 - 6 on the x-axis. Plot the percent frequency of each variation on the y-axis. Be sure to title your graph and label the axes and the three graph lines. Conclusions: Describe the pattern of change for each beak type as displayed in your graph. Identify the most successful beak type or types and suggest reasons for the success. Did the frequency of the different beak variations change when the food supply changed? Relate this to what you learned about the finches on Daphne major. How do you think the results of the research might have been different if the Grants’ beak-depth variations were not genetically-based traits (were not passed on from generation to generation)?
