And in the aftermath of the extinction event, they survived and thrived, taking advantage of an ecological vacuum other animals left behind. About 9 in 10 frog species today evolved from three frog lineages that survived the event, which occurred at the boundary between the Cretaceous and Paleogene periods, according to research published Monday in Proceedings of the National Academy of Science.

What this research shows, Wake says, is that frogs have the proven ability to “[take] advantage of opportunities — in this case [an] ecological vacuum that existed following the mass extinction.”
