Cloning the Mammoth: A Complicated Task or Just a Dream?

Recently there has been growing interest in applying the most advanced embryological tools, particularly cloning, to bring extinct species back to life, with a particular focus on the woolly mammoth (Mammuthus primigenius). Mammoth's bodies found in the permafrost are relatively well preserved, with identifiable nuclei in their tissues. The purpose of this chapter is to review the literature published on the topic, and to present the strategies potentially suitable for a mammoth cloning project, with a frank assessment of their feasibility and the ethical issues involved.
