Got wings? Lessons on the survival of the skilled

Alexandria Valerio's picture

In a recent exhibition at the American Museum of Natural History in New York City, “Dinosaurs Among Us,” paleontologists use prehistoric fossil records of bones, feathers, and nests to show that some dinosaurs did not go extinct but, rather, evolved into the creatures we see today. The links they trace show how avian dinosaurs (ones that fly) evolved into modern-day birds. Paleontologists argue that avian-dinosaurs’ swift aerial mobility played a key role in determining their survival while their land-based relatives failed to thrive. Flight enabled them to relocate and adapt to drastically changing environments—a skill that their land-based relatives lacked.
