The similar nature of the flight/wings of insects, birds, pterosaurs, and bats is example of convergent evolution
Explanation:
Convergent evolution involves different species, that are distantly related, adapting in a similar way to a similar environment to produce analogous s that perform the same function.
This is different from divergent evolution where a part of a species’ population evolves differently in another niche or environment and speciates into another species developing divergent traits.
