Should We Bring Extinct Species Back to Life?

De-extinction, the science of bringing back extinct life, is the subject of the April 2013 cover story of National Geographic magazine. Once only an idea in science fiction, today it is poised to become reality. Researchers working to bring back animals like the passenger pigeon and woolly mammoth discuss the implications of their work.
