Actually, cloning is a phenomenon that occurs naturally in a wide variety of species. Whenever you see a pair of identical twins, they are examples of nature’s clones. Although scientists have been cloning certain plants like the carrot quite successfully for decades, attempts at cloning animals have not been as successful. However, they began long before the birth of Dolly, the sheep—the first mammal to be successfully cloned.
