The medium ground finches beak increased form 1976-1978 because of natural selection.

Evidence
The average beak depth before the drought was 9.65mm. During and after the drought it was 10.71mm \

Reasoning
The reason the beak depth is different is because the finch had 2 food sources before the drought. The Portulaca was a soft plant that had seeds that were easy to get to, this was the finches main source of food. The other plant was the Tribulus. This plant had seeds that were hard to get into. During the drought only the Tribulus survived along with the birds who figured out how to eat the seeds.

Evidence
The average rainfall before the drought(1976) was 130mm. During the drought(1977) the average rainfall was only 20mm. After the drought(1978) the average rainfall was 540mm

Reasoning
This shows how much rainfall the island of Daphne Major got before, during, and after the drought.

# data[].attributes.body
Evidence
The Portulaca during the brought was averaging 3 per square meter. The Tribulus during the drought was averaging 7.33 per square meter.

Reasoning
The Portulaca was the finches main food source before the drought and the birds that did not adapt to the Portulaca plant dying off died. The ones that adapted and starting eating the Tribulus survived the drought.
