Why evolve more when they've already figured it all out?

    To fly maybe. Not sure, it just seems biologically conservative when every other surviving dinosaur became birds, fish, and mammals.

    Thank God crocodiles didn't learn to fly.

    Fish existed first, reptiles evolved from fish. Mammals evolved from reptiles alongside dinosaurs who also evolved from reptiles.

    The only dinosaurs that survived the mass extinction 65 million years ago were birds.

    Evolution isn't always a forward process. Hence how we have cetaceans and why crabs evolved into existence five separate times.
