Scientists in Australia have resurrected a once extinct species of frog that gives birth through its mouth. This frog is known as the gastric-brooding frog.

This special frog became extinct in 1983 from unknown causes. Researchers at the University of Newcastle in Australia recovered cell nuclei from tissues collected in 1970 that were preserved in a freezer. The scientists then reactivated the dead cells into living ones and revived the extinct frog’s genome in the process.

This project has demonstrated how this technology can be used as a conservation tool for species that are in decline.
