SCIENTISTS have cloned the first endangered species in the US ever, a black-footed ferret, from an animal that died three decades ago.

Willa was one of the last wild black-footed ferrets to be captured and after she died in the 1980s, her cells were frozen.
“Although this research is preliminary, it is the first cloning of a native endangered species in North America, and it provides a promising tool for continued efforts to conserve the black-footed ferret,” said the service’s mountain-prairie region director Noreen Walsh.
The Wyoming Game & Fish Department preserved Willa’s genes and sent her tissue samples to San Diego Zoo Global’s Frozen Zoo in 1988.
Willa’s frozen cells were viable for producing her genetic copy.

“We’re far from it now as far as tinkering with the genome to confer any genetic resistance, but that’s a possibility in the future.”

A second clone died.
Black-footed ferrets have dark feet and black eye markings that look like a robber’s mask.
The animals are nocturnal, live in burrow colonies and eat prairie dogs.

They are the only ferret native to North America and were once believed to be extinct.
However, a rancher in Wyoming found a small population of black-footed ferrets in 1981 and they were caught for a breeding program aimed at saving the species.
Only seven black-footed ferrets were bred and the living animals were closely related, which limited their genetic diversity and made them less resilient to disease and adapting to different environments.

San Diego Zoo Global, the Association of Zoos and Aquariums, the private pet cloning company ViaGen Pets & Equine and the conservation group Revive & Restore, are working together to produce more black-footed ferret clones.
“Biotechnology and genomic data can really make a difference on the ground with conservation efforts,” said lead scientist Ben Novak of Revive & Restore, which worked on cloning the ferret and horse.
