In Dawn Park, certain seed-eating birds are able to crack seeds according to the size of their beaks. Long beaks are able to crack larger seeds; whereas shorter beaks are able to crack smaller seeds. At one time, the number of birds with long beaks was similar to the number of birds with shorter beaks.

After a several-years drought, smaller seeds became scarce, but drought-resistant trees continued producing larger seeds. Over time, most of the birds in Dawn Park had long beaks. Which statement explains what most likely happened?
