cast doubt on that timeline.e. via bird droppings) and the forests have never been the same “The passenger pigeon is a very important ecological species for the habitat that we want to restore” Novak says A specimen of passenger pigeon The Natural History Museum/Alamy Stock Photo How do you de-extinct an animal There are three main approaches to de-extinction scientists talk about The first called backbreeding involves finding living species that have traits similar to the extinct species Then scientists would selectively breed these animals to try to make a version that more closely resembles the extinct animal—a process already underway for some extinct species like aurochs This isn’t really a true de-extinction but it might still let us fill in missing ecological functions In the case of mammoths scientists might try to mate Asian elephants with more body hair than usual for example A second option is cloning Scientists would take a preserved cell from a recently extinct animal (ideally before the last of its kind died) and extract the nucleus They would then swap this nucleus into an egg cell from the animal’s closest living relative and implant the egg into a surrogate host (Researchers actually did this in 2007 and a common goat gave birth to an extinct species the Pyrenean ibex The infant lived only 7 minutes however because of genetic problems with its lungs) Cloning may eventually give us basically identical genetic copies of extinct species but we’ll be restricted to animals that went extinct more recently and have well-preserved cells with intact nuclei The mammoth and the passenger pigeon may never be cloned The newest option is genetic engineering Here researchers would line up the genome of an extinct animal with that of its closest living relative They would then use CRISPR and other gene-editing tools to swap relevant genes from the extinct animal into the living species and implant the hybrid genome into a surrogate (or grow it in an artificial womb) This approach doesn’t produce genetically identical copies of extinct animals but rather modern versions of an animal engineered to look and behave like its extinct relatives This is the technology being used by the mammoth and passenger pigeon groups How close are we That depends on what you count as a true de-extinction which is sort of a gray area If scientists engineer an Asian elephant to have small ears extra fur and more body fat by swapping in mammoth DNA is it still an Asian elephant “If you’re willing to accept something that is an elephant that has a few mammoth genes inserted into its genome and therefore is able to make some proteins that mammoths might we’re probably closer to that” says Beth Shapiro author of How to Clone a Mammoth: The Science of De-Extinction and an evolutionary biologist at UC Santa Cruz specializing in ancient DNA The passenger pigeons project faces similar questions Novak wants to resurrect the bird using its closest living relative the band-tailed pigeon but how many genes need to be swapped to constitute success is somewhat arbitrary “The two genomes are 97% the same That 3% has built up over many millions of years and the majority of it is noise” he says “So the actual differences are much likely a smaller portion—probably within the realm of several thousand mutations What we want to find is the key 20 or 100 mutations that affect the traits that are most important” There’s also a divide as to what constitutes a de-extinction success for the scientists versus the public Genetically coaxing to behave like their extinct relatives might restore the ecosystem’s lost function Novak says But is that good enough to count “I don’t think anyone in the world is really going to call it de-extinction unless the bird looks right” Even if researchers can pinpoint and transfer those key mutations (a daunting task) DNA is only half the battle From there it’s a matter of getting the hybrid cell to grow in a surrogate hoping all the genes work harmoniously together bringing the hybrid to term and hoping it acts like the extinct species even though it was raised by a modern relative If all that goes right you still need the hybrids to mate and give birth to fertile offspring “I think the hardest part is getting developmental biology to go” says Philip Seddon a conservation biologist at the University of Otago Dunedin in New Zealand and the lead author on a recent report by the International Union for Conservation of Nature (IUCN) that issued guidelines for de-extinction research It’s a monumental task but Novak says that if his team can secure enough funding “there’s no reason that we can’t have the first generations of passenger pigeons by something like 2022 to 2025 Everyone running these projects would very much like to be in 10-year time frames” A drawing of lesser stick-nest rats Museum Victoria/Artist: John Gould/Lithographer: HC Richter How do we choose which animals to de-extinct In their recent publication Douglas McCauley an ecologist at UCSB and his colleagues argue for three criteria to consider when choosing de-extinction candidates: Select target species with unique functions concentrate on species that went extinct recently and only work with species that can be restored to levels of abundance that meaningfully restore ecological function Although the mammoth and the passenger pigeon might pass McCauley’s first criterion experts are skeptical about whether they’re truly the best animals to focus on Shapiro points out that ecosystems are not static and have continued to change since these animals went extinct “I worry about the dramatic changes to the forest in the eastern part of the North American continent” she says “I think there’s a lot we need to understand better about the passenger pigeon’s ecology and the effect that the passenger pigeon would have on that habitat before we can make a sufficiently educated decision” McCauley has similar worries: “Forests have fragmented forests have expanded and contracted A passenger pigeon that hits that forest again is going to be like a middle-aged guy who really wants to go back to high school and then he gets back there and he’s like ‘Whoa I don’t fit in anymore’” He thinks that de-extinction efforts should instead be focused on recently extinct animals like the Christmas Island pipistrelle bat (Pipistrellus murrayi) the Réunion giant tortoise (Cylindraspis indica) and the lesser stick-nest rat (Leporillus apicalis) Although not as charismatic as a woolly mammoth he says these creatures still have habitats to return to and would restore a unique function in their ecosystems The lesser stick-nest rat for instance did what its name implies and built large stick nests in central Australia that became hubs of biodiversity What are the risks The spread of genes can be difficult to control We probably won’t lose track of mammoths in Siberia but what about rats “It becomes hard to control those sorts of populations” Seddon says “And there are the same fears one might have about genetically modified crops—the idea that a modification may move into relatives may jump in and out or may not be expressed in the way that you expect” Scientists are confident that there’s a safe way to proceed but mistakes may come at a high cost if we can’t put the genie back into the bottle if something goes wrong “If we lose sight of the true gravity of extinction and overzealously embrace de-extinction as a mitigation tool it would be really easy to manufacture forests savannas and oceans full of Franken-species and Eco-zombies” McCauley says But in spite of any danger McCauley says his biggest concern isn’t a runaway genetic experiment wreaking havoc on a fragile ecosystem “Honestly the thing that scares me most is that the public absorbs the misimpression that extinction is no longer scary” he says “That the mindset becomes: Deforest no biggie we can reforest If we drive something extinct no biggie we can de-extinct it” Introducing (or reintroducing) a new species to a habitat always comes with some risk but de-extinction scientists point out that we’ve been able to manage that risk successfully with living animals like reintroducing wolves into Yellowstone National Park or beavers into the United Kingdom There have also been disasters like the poisonous cane toad in Australia which was originally imported to help control the gray-backed cane beetles that were damaging sugar crops but is now spreading across the continent and depleting native populations “De-extinction is just the next step in a progression that conservation has already been on” Novak says “If you want to restore the ecological function of an extinct species and you don’t have any living species that will do that you take the closest living species you can get and adapt it based on the genome of the extinct species” IUCN has been dealing with these sorts of issues for years now and so stands uniquely poised to help regulate de-extinction science’s future Still there are no laws requiring that researchers take its advice The only legal structures governing de-extinction are borrowed from genetically modified organism and cloning research—fields regulated by the US Food and Drug Administration Department of Agriculture and Environmental Protection Agency Regardless de-extinction is speeding closer to reality and now is the time to start thinking about it McCauley says “For a long time it was easy to just put it aside because the technology wasn’t there” he says “But I don’t think we can do that anymore” especially the CRISPR-Cas9 revolution,” Clifford added.0 degrees Celsius while Kupwara district town also reeled under
