In the Siberian permafrost extinct Wooly Mammoth DNA has been recovered that has been turned over to the Japanese for a cloning project that began in 2011. Japanese scientists hope to start the cloning process by first using the extinct Mammoth DNA with an African elephant to produce a hybrid and then reintroduce more extinct DNA into the hybrid species, and so on until eventually they reach a near-perfect clone of the original species. Sci-fi? No as during WW2 the Germans backbred the Tarpan Horse and Auroch Cattle out of extinction using that method. Theoretically, any species can be brought back IF survivng species still carry those genes OR if preserved extinct genetic material can be extracted and used with a surviving relative to create a hybid species that is modified further and further until they get back to the original species. Cloning is a hot trend for bringing back extinct species- the Thylacine being the most requested...
