![]() "The way it is going now, I can see why people would imagine it (de-extinction) is possible," said Poinar. The DNA sample would have to be well preserved and techniques would have to improve to reduce the risk of deformity, miscarriage and premature death, a characteristic of animal cloning today. Australian teams are working on reviving the Tasmanian tiger with DNA obtained from an ethanol-preserved pup of the dog-like, marsupial predator that died out in the 1930s. Tasmanian tigers or Thylacines are photographed at Beaumaris Zoo in Hobart in 1918. ![]() In Japan, geneticists said in 2011 they planned to use DNA from frozen carcasses to resurrect within six years the woolly mammoth which died out during the last Ice Age.Īnd in Britain, Oxford University scientists have obtained genetic data from museum-held remains of the dodo, the flightless Indian Ocean island bird hunted to extinction by 1680. The cloned embryos all died within a few days.Īustralian teams are also working on reviving the Tasmanian tiger with DNA obtained from an ethanol-preserved pup of the dog-like, marsupial predator that died out in the 1930s. Just last month, a team at Australia's University of New South Wales said they had cloned embryos of the gastric-brooding frog which died out in 1983 and was named for its weird reproductive technique of swallowing its eggs, brooding them in its stomach and then spitting out the offspring. This was the first cloned animal born from an extinct subspecies, but the success was mixed-the kid, borne by a domestic goat, died within 10 minutes from a lung abnormality. In 2009, researchers announced they had cloned a bucardo, also called a Pyrenean Ibex, using DNA taken from the last member of this family of Spanish mountain goats before she died in 2000. Oxford University scientists have obtained genetic data from museum-held remains of the dodo, the flightless Indian Ocean island bird hunted to extinction by 1680. Technologies developed as part of the potential de-extinction process could eventually have uses for human beings as well.Ĭolossal CEO Ben Lamm told Axios that “growing humans ex utero, full gestation, I do think at some point that technology is inevitable,” although he noted that ethical concerns would drive more resources towards improving in-vitro fertilization in the interim.A fragment of a femur bone from the extinct dodo is held up in front of an illustration from Martyn's 'A New Dictionary of Natural History' published in 1785 in London on March 27, 2013. The hope is that we can use, first, comparative genomics so we can get at least one, and hopefully more, dodo genomes that we can use to look and see how dodos are similar to each other, and different from things like the solitaire,” or Nicobar pigeon, Ms. ![]() ![]() “Once a species is extinct, it’s really not possible to bring back an identical copy. For the dodo, the closest relative is the Nicobar pigeon for the wooly mammoth also being worked on by Colossal, African and Asian elephants are used. ![]() De-extinction uses DNA from preserved samples of extinct species, as well as DNA from close living relatives. ![]()
