You're likely already familiar with Dolly -- the sheep that achieved near celebrity status as the first mammal to be cloned successfully using adult animal cells. But although Dolly has been one of the few cloned animals to attract widespread fame, she's not alone. The world's first clone -- a tadpole -- was actually created in 1952 [source: Human Genome Project]. And at least a dozen different species have been cloned since: everything from the common cow to the endangered guar, a type of wild ox. You can learn more about the science behind cloning in How Cloning Works.
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 derived from the clones of cows, pigs and goats are safe for human consumption intensified an already growing interest in the process.
Cloning has additional uses besides its ability to help farmers breed consistently top-notch burgers and bacon. Other potential applications include the preservation of species, biomedical research, drug and organ production and even commercial ventures that aim to keep little Fido (or at least a convincing substitute) in the family forever.
