The graphs here show the distribution of beak depths for the ground finches on Daphne Major, an island in the Galapagos. The bird beaks were measured over a multi-year study, including a time period before and after a drought. The drought reduced the supply of
seeds and left most of the seeds as thick-walled nuts that survived the drought. Analyze the data and select the claim about natural
selection and genetic diversity that is supported by the data.
