True or False: Based on the shapes of the graphs below, there is variability in the beak depth trait among the finches. Beak Depths of 50 Medium Ground Finches That Did Not Survive the Drought Beak Depths of 50 Medium Ground Finches That Survived the Drought Figure 1. The two graphs above show the beak depths, measured in mm, of 100 medium ground finches from Daphne Major. Fifty birds did not survive the drought of 1977 (top graph). The other 50 birds survived the drought and were still alive in 1978 (bottom graph). Select one: True False Based on the graphs below, how are the birds' beak depth measurements distributed? Beak Depths of 50 Medium Ground Finches That Did Not Survive the Drought Beak Depths of 50 Medium Ground Finches That Survived the Drought Figure 1. The two graphs above show the beak depths, measured in mm, of 100 medium ground finches from Daphne Major. Fifty birds did not survive the drought of 1977 (top graph). The other 50 birds survived the drought and were still alive in 1978 (bottom graph). a. They are distributed around the median. b. They are distributed around the tails. c. They are distributed evenly. d. They are distributed around the mean During the drought there was change in available food for the birds. Many of the small, soft seeds did not survive, and only large, hard seeds remained for the birds to eat. Based on this information, which of the following is the most probable hypothesis for the shift if beak size we see in the graphs: Beak Depths of 50 Medium Ground Finches That Did Not Survive the Drought Beak Depths of 50 Medium Ground Finches That Survived the Drought Figure 1. The two graphs above show the beak depths, measured in mm , of 100 medium ground finches from Daphne Major. Fifty birds did not survive the drought of 1977 (top graph). The other 50 birds survived the drought and were still alive in 1978 (bottom graph). a. The shift to larger, harder seeds selected for birds with larger beak depths (they were better able to use open the large seeds). b. Large beaked birds migrated to the island in a single year. c. Birds with smaller beaks could more easily chip away at the larger seeds. True or False: Based on the standard deviations in the graphs in the above questions, we can conclude the two data sets have the very similar amounts of variability compared to the means of each data set (i.e., the data are equally spread out). Select one: True False .
