Answer:
Convergent Evolution
Step-by-step explanation:
This is a form of independent evolution where similar features are developed by two species,which are not closely, living in different periods but the same biome.
Due to developing analogous structures they may appear to be similar. Most of these structures were not present in the last common ancestor of both groups. An example is the nature of wings in birds, bats and insects which serves the same purpose which is flight.
