Natural selection caused the average beak size of the Medium Ground Finch population on Daphne Major to increase from a depth of 9.65 mm and a length of 10.71 mm to a depth of 10.55 mm and a length of 11.61 mm.

Natural Selection caused the smaller, thin beaked finches died off from not being able to eat because of the drought as they were unable to eat the larger, harder seeds of the Tribulus plants. This caused their population to decrease from 751 in the summer of 1976 to 90 left on the island by the end of 1978.
