Reawakening Extinct Species

  • Aired: 04/22/2014

  • Rating: NR
Using new genetic technologies, scientists are trying to bring back extinct species. Meet researchers working to revive the passenger pigeon, once the most abundant bird in the world, and the woolly mammoth, which they say could slow down the melting of Arctic permafrost. It may be possible, but is it right to turn back the clock?
