Our experiences have told us that, with a little work, we humans can clone just about anything we want, from frogs to sheep—and probably even ourselves. 
In 2009, scientists had their first near-success resurrecting an extinct animal. Using goats as egg donors and surrogates, they made several clones of a wild mountain goat called the bucardo—but the longest-surviving clone died soon after birth.
For now, risks and technical challenges—as well as laws that make it illegal—will probably keep human reproductive cloning from becoming a reality. Even though many species have been cloned successfully, the process is still technically difficult and inefficient. The success rate in cloning is quite low: most embryos fail to develop, and many pregnancies end in miscarriage.


Scientists clone the first U.S endangered species
Elizabeth Ann was born and is being raised at a Fish and Wildlife Service black-footed ferret breeding facility in Fort Collins, Colorado. She’s a genetic copy of a ferret named Willa who died in 1988 and whose remains were frozen in the early days of DNA technology.
 Cloning makes a new plant or animal by copying the genes of an existing animal. Texas-based Viagen, a company that clones pet cats for $35,000 and dogs for $50,000, cloned a Przewalski’s horse, a wild horse species from Mongolia born last summer.
The seven-year effort to clone a black-footed ferret was far less theoretical, he said, and shows how biotechnology can help conservation now. In December, Novak loaded up a camper and drove to Fort Collins with his family to see the results firsthand
When Willa, one of the few black-footed ferrets left, died, the Wyoming Game and Fish Department sent her tissues to a “frozen zoo” run by San Diego Zoo Global that maintains cells from more than 1,100 species and subspecies worldwide. Eventually scientists may be able to modify those genes to help cloned animals survive.

Will cloning ever save endangered animals?
In 1958 John Gurdon, then at the University of Oxford, and colleagues cloned frogs with nuclear DNA extracted from the cells of fully formed tadpoles. Unlike embryonic cells, which are genetically flexible enough to become a variety of different tissues, a tadpole's cells are "differentiated"—that is, the patterns of genes they express have changed to fit the profile of a specific cell type: a skin, eye or heart cell, for example. Gurdon demonstrated that, when transplanted into an egg, nuclear DNA from a mature cell reverts to the more versatile state characteristic of DNA in an embryo's cells. This breakthrough encouraged scientists to try cloning far larger animals using DNA from adult cells.
Some researchers see ways around these problems. Pasqualino Loi of the University of Teramo in Italy was part of a team that successfully cloned endangered mouflon sheep in the early 2000s Scientists have also figured out how to encourage nuclear reprogramming by bathing the egg in certain compounds and chemicals, such as trichostatin A, which stimulate or inhibit the enzymes that determine a cell's epigenome. Most recently, Teruhiko Wakayama of the RIKEN Center for Developmental Biology in Kobe, Japan and his colleagues produced 581 cloned mice from a single donor mouse over 25 generations, using a chemical called trichostatin A to achieve success rates as high as 25 percent in some but not all generations.
