The beak size increased on finches because the ones with the small beaks died due to no food source which left only the finches with the thicker and longer beaks left and they produced off spring with thicker longer beaks so the population increased and the Portulaca seed went basically extint and the Tribulus seed grew more.

There was drought and the  rainfall decreased majorly on Daphne Major due to the drought in 1976-1978.The drought caused some of the finch population to die out but the ones left reproduced other finches with long beaks.

The average Beak size increased on Daphne Major for the medium ground Finch population.In 1976 the average beak size for the finch was 10.7 mm long and 10.2 mm deep.In 1978 the average beak size was 11.6 mm long and 10.5 mm deep.(Google sheets)

In 1976 the average rainfall on Daphne Major was  130 mm then it dropped in 1977 to 20 mm of rain a year.(Google sheets

Due to the drought most of the small beaked finch population died out because due to the drought the Portulaca (soft shell seed) seed was not able to grow so the small beaked finches had no food source for them to eat which left only the Finches with the harder and bigger beaks because the Tribulus seed (harder shell seed)which left them a food source so the survived.The bigger beak finches reproduced and made the big beak finch population increase on Daphne Major.

The thin beaked birds died out because they couldnt eat the Tribulus seed because it was to hard so they had no food to live on.From November 1976 the Finch population on Daphne Major was 751.In November of 1978 the Finch population was 90 0f 243.(Google Sheets)

Natural selection caused the beaks of the medium ground finch population on Daphne Major to increase size from 1976-1978.
