Final answer:
Convergent evolution is the development of similar traits in organisms that do not share a common ancestry but face similar environmental conditions. An example of this is the development of wings for flying in insects and birds, which evolved from different original structures.
Step-by-step explanation:
An example of convergent evolution is the development of the same function, flying, in organisms that do not share a recent common ancestry, such as insects and birds. The fact that wings that allow flight have developed from very different original structures suggests that the process of natural selection can produce similar adaptations in two very different types of organisms who share a similar environment.
