Passenger pigeons might find the rebounding forests of the eastern United States a welcoming home. Thats more than 65 million years ago. But what if they somehow survived? Genetic technologies can enable researchers to bolster animal populations by helping them adapt to a changing environment, build natural resistance to a disease, or introduce genetic diversity to their gene pool. . A new species of ankylosaur is unlike any other dinosaur found to date. Can we bring a species back from the brink?, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC.

Animals That Scientists Want to Bring Back From Extinction And yet for Greely, as for many others, the very fact that science has advanced to the point that such a spectacular feat is possible is a compelling reason to embrace de-extinction, not to shun it. If the Sooam researchers do find such a cell, they could coax it to produce millions of cells.
