Back From the Dead
Scientists are trying to bring extinct species back from the dead. Will they recreate something dangerous? In the March 19th edition of the New York Times, Gina Kolata quotes geneticist George Church as saying, "Maybe we can no longer delay death, but we can reverse it." So far only one extinct species has been brought back: A goat-like creature that went extinct in 1999. In 2003, it was cloned from frozen cells, but it lived only a few minutes. Cloning needs an intact cell, which, in an extinct species, may not exist. If it works, the embryo must be implanted in a closely related species.
