Passage 27
If you didn’t know any better, you might think that Star, Snuppy, CC and ANDi were just a bunch of interesting names. You’d only be half right. These creative names _1_ belong to a pig，a dog, a cat and a monkey that were among the first clones of their species.
You’re likely already familiar with Dolly—the sheep that achieved near _2_ status as the first mammal to be cloned successfully using adult animal cells. But Dolly is not alone. The world's first clone—a tadpole—was actually created as early as in 1952. And at least a dozen different species have been cloned since: everything from the common cow to the _3_ guar, a type of wild ox.
Animal cloning has come a long way since that first tadpole more than 50 years ago. The U.S. Food and Drug Administration's (FDA) declaration in early 2008 that food products _4_ from the clones of cows, pigs and goats are safe for human consumption _5_ an already growing interest in the process.
Cloning may have _6_ uses besides its ability to help farmers _7_ breed quality burgers and bacon. Other potential uses _8_ the preservation of species, biomedical research, drug and organ production and even commercial ventures.
It seems that finding out exactly how many cloned animals have been produced is almost as difficult as producing them in the first place. There’s no official _9_ of clones, and laboratories aren't required to report every single tadpole or mouse they create. But armed with a bit of knowledge concerning animal cloning and its _10_, it’s likely to narrow down the contestants to a possible field.
