one of the birds on the galapagos islands is the medium ground finch. these birds prefer to eat small seeds, which are easier to eat than large seeds. however, when food is scarce, such as during a drought, some of the birds can eat larger seeds. the ability to crush and eat larger seeds is related to break thickness, an inherited characteristic. birds with thicker beaks are able to crush large seeds more easily.
-describe the changes that would occur in the medium ground finch population during a long period of drought when food is scarce.
-explain how this set of changes is an example of the process of natural selection
