![]() Attempts at bringing woolly mammoths back from extinction may fail many times before a viable mammoth is born. Woolly mammoths were social animals that lived in herds. ![]() In a "first step" toward resurrecting the mammoth, researchers from Russia and South Korea are working to bring back another extinct animal, the Lena horse, using cells from a 40,000-year-old foal found in Siberia.ĭespite all the enthusiasm some scientists and many non-scientists have for de-extinction of this species, ethical concerns exist. The research into the genome, as well as preserved genetic material, has led to work around either creating a woolly mammoth through cloning or through editing the genome of the closest living relative, the Asian elephant. Paleogeneticists, scientists who study preserved genetic material, have sequenced the woolly mammoth genome. Many woolly mammoth specimens remain in the permafrost of Siberia. Woolly mammoths seem like an excellent choice for de-extinction. Mauricio Antón / Wikimedia Commons / CC BY 2.5 Here's our list of 14 extinct animals considered for de-extinction through cloning. A real-life Jurassic Park is probably best reserved for the imagination, but a real-life Pleistocene Park? Well, that's another story. That leaves tackling whether undertaking revivifying or resurrecting an extinct species is sensible, ethical, safe, and affordable.īecause of the sheer amount of time that has passed, dinosaurs are unlikely candidates. For instance, recently extinct animals, museum specimens, and species preserved in permafrost during the last Ice Age provide ancient DNA. Some species have substantial potential as candidates because of the availability of what is called ancient DNA, or genetic material from fossils or artifacts. To successfully clone an extinct animal, scientists need to find animal DNA that is almost entirely intact. ![]() While the science of cloning is still in its infancy, many scientists believe it's only a matter of time before extinct animals again walk the Earth. Can a lost species become un-extinct? In the 1993 film "Jurassic Park," dinosaurs are cloned back to life after their DNA is found intact within the bellies of ancient mosquitoes preserved in amber.
