Although controversy surrounds cloning efforts, the cloning of animals to assist efforts to preserve genetic variation in support of endangered species conservation efforts has attracted serious interest. A recent report by Loi et al. describing the cloning of a mouflon (a species of wild sheep) in a domestic sheep surrogate points to potential conservation opportunities and additional challenges in the evaluation of appropriate technologies for present and future efforts to conserve gene pools of endangered species.
