00:05Scientists work to bring extinct animals back through de-extinction technology.
00:10Across frozen tundra, island forests, and museum labs, scientists study bones, feathers,
00:15embryos, and preserved tissue. The woolly mammoth could walk arctic ground again after
00:19researchers edit Asian elephant DNA for cold-resistant traits. The dodo once waddled
00:24through Mauritius forests, and scientists now study Nicobar pigeon DNA to rebuild dodo-like
00:29traits. The Tasmanian tiger paced inside old black-and-white film, while researchers compare
00:34thylacine DNA with living marsupial relatives. The Carolina parakeet flashed green, yellow,
00:40and orange across American forests before hunters, disease, and habitat loss erased it.
00:45The passenger pigeon once filled North American skies, and scientists now study band-tailed
00:50pigeon DNA for possible flock restoration. The quagga grazed South African grasslands with zebra
00:55stripes in front and a brown horse-like body behind. The moa towered over New Zealand forests,
01:00and researchers examined preserved bones and eggshells for ancient DNA. The Irish elk crossed
01:06open woodlands with antlers that could stretch 12 feet across its head. The Baiji dolphins swam
01:11China's Yangtze River, where boat traffic and pollution helped push it into functional extinction.
01:16The great auk dove through North Atlantic water using short wings like paddles before hunters
01:20destroyed the last birds. The Stellar's sea cow drifted through North Pacific kelp beds,
01:25reaching 30 feet before hunters killed it within decades. These de-extinction projects share one
01:31pattern. Old DNA needs living relatives, careful labs, and places safe enough for return. A museum
01:38specimen may become more than a display when a living animal opens its eyes.
