The finches all appeared to be related but differed from the mainland population.
Charles Darwin was a scientist famous for proposing the evolution theory and the theory of survival of the fittest. His discovering came during one of his many voyages, when he noticed that finches on an island where different from the finches of the mainland although the looked almost similar. The most striking feature was that their beaks were adapted to whatever type of food was found on their territory.
In honour of his work, the finches were renamed Darwin’s finches.

Answer: The finches all ate the same materials as the mainland population.
Reason for the answer: Darwin concluded that regulation of the protein is the principal way in which beak variation occurs in the finches. The differences were acted upon by natural selection and resulted in the evolution of the finch species, which led Darwin to his theory.
