According to this article a group of scientists are attempting to clone a woolly mammoth. The scientists from Russia and Japan claim that a thigh bone found in August contains marrow cells that are well preserved enough to form the starting point of a cloning experiment. They hope that the cloning will be complete within the next five years, although others have cast doubt on whether it will be possible. The team will extract a nucleus from the animals bone marrow and insert it into the egg of an African elephant. It will be interesting to revisit this at a later date and see how successful the experiment is.
