Use the information and migration map to answer the following question.
Thousands of years ago, a large flock of birds was driven from its normal migratory route by a severe storm. The birds scattered and found shelter on two distant islands, as shown on the map. The environment of Island A is very similar to the birds original festing region. The environment of Island B is very different from that of Island A. The birds have survived on these islands to the present day with no migration between the populations. Which statement MOST accurately predicts the present-day conditions of these island hawk populations?
The birds that landed on Island B have evolved different traits than those on Island A.
B) The birds that landed on Island A have evolved similar traits to those on Island B.
C The birds on Island A have given rise to many new species.
D The bird populations on Islands A and B have undergone identical mutations.
