Actually the Tasmanian Wolf (I just like saying that more then Thylacine) is on a list of animals that are priority for being brought back from extinction because we actually have their DNA intact, and there are 2 samples that are not damaged. My profesor is actually studying this right now. Some of the animals we maybe able to bring back in the next 20 years are the Quegga, Passenger Pigeon, Caspian Tiger, Dire Wolf, Wooly Mammoth, and a few others including that we were respondsible for making extinct. However, with the wooly mammoth it would actually take 25 to 30 to have pure breed wooly mammoths starting off from a hybrid. (It's rough but then again they're cloning alot of things that they are not telling the public about like the cloning of the cat wasn't supposed to be let out) lol.   mcelite
