The first successfully cloned endangered animal 第一只被成功克隆的濒危动物

This black-footed ferret（雪貂）is not only cute,she is beyond special.Meet Elizabeth Ann,the first endangered animal to be successfully cloned in North America.

In a joint scientific effort between the US Fish and Wildlife Service,and a combination of other organizations,an endangered species was successfully cloned.This is a huge deal on so many levels,especially for the future of species biodiversity.

Back in 2013,an organization called Revive & Restore popped up on the radar of the US Fish and Wildlife Service.Their goal is to“involve bio-technologies in standard conservation practice”.There's no denying that biodiversity hasgreat importance in conservation efforts when there are a few living animals of a species left.

Before that,way back in 1985,genetic samples from Willa,a wild black-footed ferret,were shipped to a geneticist at the San Diego Zoo.These genetic samples led to the ferret alive today.Dr Ryder,the aforementioned geneticist,works at a place called the Frozen Zoo.This incredible place houses the “largest and most diverse collection of its kind in the world”.This frozen library of life contains over 10,000 living genetic samples.The combined achievement to successfully clone the endangered blackfooted ferret is big news for this organization.

Elizabeth Ann's journey towards life began when all of the above organizations teamed up with ViaGen Pets & Equine,a commercial cloning company.A domesticated ferret was used to implant the created embryos,which was successful.Then on December 10,Elizabeth Ann was born via C-section （剖宫产）.She was cared for,and once she was stable,tests were done to confirm her genetic makeup.

Other clones from Willa's samples will join Elizabeth Ann at her current home at the National Black-footed Ferret Conservation Center in Colorado.This exciting experiment will continue as scientists work towards understanding the effects that these clones will have on the larger ecosystem,and if they will ever be able to be integrated into the wild population.

These developments are beyond exciting for the protection of many lost and endangered species.All eyes are on the Frozen Zoo and the future of cloning to protect and revitalize(使……恢复生机)threatened species around the world.
