To be able to go farther. If fish were good enough swimmers, why did
some of them need to walk? Because it opened up possibilities. Or
perhaps the environmental conditions changed so that the gliders favored
territory became smaller and more dispersed, so that they needed powered
flight to get around between them. Who knows? If new niches were never
availible, or conditions always stayed the same, there would never be
adaptive radiations at all, or any other evolution for that matter.
