In this photo provided by the U.S. Fish and Wildlife Service is Elizabeth Ann, the first cloned black-footed ferret and first-ever cloned U.S. endangered species, at 50 days old on Jan. 29, 2021. Scientists have cloned the first U.S. endangered species, a black-footed ferret duplicated from the genes of an animal that died over 30 years ago. They hope the slinky predator named Elizabeth Ann and her descendants will improve the genetic diversity of a species once thought extinct but bred in captivity and reintroduced successfully to the wild.
