Question

Darwin observed that the finches on two different islands in the Galapagos belonged to the same family, but showed a lot of variations in their beak size and shape. How can this variation be justified?

Answer 1

A)migration to an environment different from their birthplace, and adaptation to the available food, ultimately leading to speciation

B)migration to the same environment as their birthplace, and sudden mutation, ultimately leading to formation of different races

C)migration from their original birthplace to a different environment, and modification of the habitat according to their specific need, ultimately leading to speciation

Answer 2

I would immediately eliminate B because birds don't have races... And since the question is talking about beak size and bird use their beaks to eat. So in the end I would go with A.
