In 1977, Daphne Major experienced a severe drought. The figure (above) shows the beak depths of the initial population of medium ground finches before the drought (red bars), and of the drought survivors (black bars). What do the data show? Which of the following statements is not true?
1) The beak depths of the initial population of medium ground finches decreased after the drought.
2) The beak depths of the drought survivors increased after the drought.
3) The beak depths of the initial population of medium ground finches were greater than the beak depths of the drought survivors.
4) The beak depths of the initial population of medium ground finches were equal to the beak depths of the drought survivors.
