Yes, they are both capable of flight, and they are both placed in different phyla. There are two concepts that make it easier to explain why.
Homologous and analogous featuresHomologous features are characteristics or organisms that share a common origin, regardless of whether they look similar or have a similar purpose. For example, human arms, bat wings, horse legs, and whale fins are also homologous because, even though they look different and do different things, they’re all derived from the same ancient ancestral appendage.Analogous features are characteristics that do the same thing, even though they DON’T come from the same place. For example, bird wings are highly specialized forelimbs (front legs or arms) that enable birds to fly. Insect wings are NOT forelimbs, but they enable insects to fly.Bats and birds both use their forelimbs to fly, so you could say that bat and bird wings are both homologous (same origin) AND analogous (same use).Convergent and divergent evolutionConvergent evolution is when unrelated organisms both develop similar adaptations. Birds and insects both evolved flight, but they did not develop flight at the same time and they didn’t even develop wings from the same parts of their bodies (bird and insect wings are analogous, but NOT homologous).Divergent evolution is when related species evolve differently, or when different populations of one species evolve differently enough to become different species (this is called speciation). For example, one group of ancient African hominoid apes evolved the ability to permanently walk upright, while others did not. This group continued to evolve more and more divergent characteristics (less hair, larger brain) until it became modern humans, which are now much different from Chimpanzees.
