In the galapagos island finches, the variation in the beak shape corresponded to which finch characteristic?

a. their diet
b. their tail shape
c. their flight ability
d. their mating habits

Correct A). Their Diet

Charles Darwin saw a different design of the beak developed in the finches on the Galapagos Island. All the finches are adapted to their island, which came up to the reproduction rate because they are fighting for the same food.

Their beaks are adapted to the food source, which was favored by the natural selection, which results in the evolution of the finch species.
