Cloning Could Save Rare Rhino

Faced with a wild population of northern white rhinos that can be counted on the fingers of one hand, scientists are turning to cloning in a last-ditch effort to save the species, the Independent reports. In a technique that could be used to pull other species back from the brink of extinction, scientists are mixing the rhino's cells with embryos of its less endangered cousin, the southern white.

The resulting offspring will have the DNA of both species, thereby saving genes that would otherwise be lost forever. "No one has done this before, but I'm confident that it can be done," said a stem-cell specialist. Conservationists hope the experimental technique will work, but say preventing habitat loss and poaching is still the best hope for endangered species. (More rhinoceros stories.)
