In reality? Probably not. On the one hand, it's not likely that extinct animals' DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well­preserved DNA.On the other hand, for example, a gaur can have a cow as a_surrogate_mother,_definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother?

　　Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today's world.Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.
