A rare wild horse produced by cloning in 2020 is now with others of his kind at the San Diego Zoo. The endangered Przewalski's Horse, named Kurt, has been introduced to a female of his species, named Holly. Wildlife care experts at the zoo hope that the introduction will result in Kurt learning the behaviors of a wild horse. He was cloned from the DNA of a Przewalski's Horse that was frozen 42 years ago. It's hoped that once he reaches maturity in three or four years, he will be able to breed and bring more genetic diversity to his species. Formerly extinct in the wild, the Przewalski's horse has survived for the past 40 years almost entirely in zoos around the world, Several wild herds have been reintroduced to their native habitat, the grasslands of China and Mongolia.
