I want to know the answer to the following question:
Active flight ability has played what kind of role for insects?
All the background I'm provided with is that "Having their muscles attached to their exoskeletons is more efficient and allows more muscle connections; crustaceans also use the same method, though all spiders use hydraulic pressure to extend their legs, a system inherited from their pre-arthropod ancestors.". Is that enough to answer the question?
Answer: no
