Eventually, the egg produced an embryo containing hundreds of cells. “There were a lot of hi-fives going around the laboratory,” says Archer. This might seem like an over-reaction. The fact that it started to grow into an embryo was a big deal. Archer’s goal is simple: To bring the extinct gastric brooding frog back from oblivion and, in doing so, provide hope for the hundreds of other frogs that are heading that way.

Simply put, the mother frog converts her stomachs into a womb. When news broke about this weird strategy, other scientists were incredulous. They didn’t have long. Then, good news!
