Black-footed ferrets, a critically endangered species native to North America, have renewed hope for future survival thanks to successful efforts by a coalition of conservationists, to reproduce genetically important offspring using frozen semen from a ferret who has been dead for approximately 20 years................ The sire, 'Scarface,' as he is affectionately called, was one of the last 18 black-footed ferrets to exist in the world in the 1980s....................Responsible and ethically correct "Jurassaic" Park science done correctly?
