Question from Campbell Biology Chapter 23:
4) Which statement about the beak size of finches on the island of Daphne Major during prolonged drought is true?
AEach bird evolved a deeper, stronger beak as the drought persisted.
BEach bird's survival was strongly influenced by the depth and strength of its beak as the drought persisted.
CEach bird that survived the drought produced only offspring with deeper, stronger beaks than seen in the previous generation.
DThe frequency of the strong-beak alleles increased in each bird as the drought persisted.
