Wings of Mosquito, Bat and Bird show evolution called
Convergent evolution- Development of similar adaptative functional structures in unrelated groups of organisms.
Wings of insect, bird and bat: Insect is an invertebrate while bird and bat are both vertebrates belonging to class aves and class mammalia respectively.
Wings in these three distantly related animals forms are used for flying in the air, but these are very different in basic structure and origin. Each has evolved from separate ancestral population differently but as a means of more efficient mode for locomotion.
So, the correct answer is 'Convergent'.
