Kurt, a baby Przewalski’s horse, looks and plays like any other baby horse. But the now two-month-old colt is unique in that he is a clone. The endangered Przewalski’s horse colt was created from stallion cells that had been frozen at the San Diego Zoo in 1980. The frozen cells were recently collected and fused with an egg from a domestic horse to create the world’s first cloned Przewalski’s horse. The process of cloning started several decades ago.
