A cloned black-footed ferret named Antonia has achieved a remarkable milestone in conservation by giving birth to two healthy kits, Sibert and Red Cloud, at the Smithsonian National Zoo. This is the first successful birth from a cloned endangered species in the U.S., as Antonia carries genetic diversity crucial for the survival of the black-footed ferret, once thought extinct. With only about 370 remaining in the wild, this achievement highlights the potential of cloning technology in revitalizing endangered species populations.
