People who are identical twins are a form of clones, too! Man-made Clones Nearly 50 years ago, scientists made the first animal clones by splitting frog embryos. In 1996 the first mammal was cloned in Scotland-a sheep named Dolly..Since then, scientists have successfully cloned other mammals. These include cows, pigs, a cat, and the first equine, a mule named Idaho Gem, was cloned at the University of Idaho in 2003.
