Lord of the Wings? ‘Lord of the Rings' director backs plan to ‘de-extinct' New Zealand bird

Yahoo10-07-2025
In a 'Jurassic Park'-esque fashion, 'Lord of the Rings' director Peter Jackson and the Texas-based biotech company Colossal Biosciences are partnering to 'de-extinct' the centuries-extinct New Zealand bird known as the moa.
The partnership, according to the The Associated Press, sprung up two years ago after Jackson learned of Colossal's work to bring back species like the wooly mammoth and the dire wolf.
A New Zealand native, Jackson is fascinated with the wingless, long-necked specimen. He called it 'part of the country's DNA,' in an interview with IGN.
The tallest of the flightless bird, the South Island Giant Moa, once roamed freely on the South Island of New Zealand, but became extinct about 600 years ago due to overhunting by the first Polynesian settlers, who arrived circa 1300.
It's particularly this rich, shared history is why Jackson wanted the involvement of the Ngāi Tahu, the principal Māori tribe of the South Island.
'The movies are my day job, and the moa are my fun thing I do,' Jackson told AP.
Jackson and his partner Fran Walsh provided $15 million in funding to kick off the moa project with Colossal Biosciences, under one condition — collaboration with the Ngāi Tahu Research Centre, per IGN.
Jackson, who owns one of the largest private collections of moa bones, facilitated the meetings between Colossal, the Ngāi Tahu and Paul Scofield, the world's leading moa expert.
The bone collection is significant enough that Scofield, who is also a senior curator of natural history at the Canterbury Museum in New Zealand, described it as a 'comprehensive collection' when helping Jackson identify the different moa species represented in his collection.
The moa project is in its early stages, as scientists are looking for well-preserved bones from which it may be possible to extract DNA, Colossal's chief scientist Beth Shapiro told AP.
The process will resemble Colossal's current approach to genetically engineer living species in close relation to the specimen they're attempting to 'de-extinct.'
Comparing the moa's DNA sequence of living bird species to other flightless creatures such as tinamou and emu will help Colossal understand what made the moa unique, Shapiro said.
But working with birds presents a special challenge because of birds' embryos development inside eggs. Transferring an embryo to a surrogate will not look like mammalian IVF.
Scientists agree that is more feasible to tweak the genes of living animals than bringing back extinct species, which is likely impossible. They also worried that focusing on extinct creatures deters from conservation efforts of currently endangered species, per AP.
According to Duke University ecologist Stuart Pimm, who is not involved in the project, if the Colossal team manages to create a bird with large feet and thick, pointed claws similar to the moa, they will also face the challenge of determining an appropriate habitat for it as reported by AP.
'Can you put a species back into the wild once you've exterminated it there?' he said. 'I think it's exceedingly unlikely that they could do this in any meaningful way.'
Pimm added, 'This will be an extremely dangerous animal.'
Some X users immediately pointed to the parallelism of extracting ancient DNA by referencing 'Jurassic Park.'
An entire X account devoted to the moa bird posted a flyer teasing a play-on-words title for Jackson's next epic trilogy: 'Lord of the Wings.'
In a Slashdot forum, a user-driven platform similar to Reddit that focuses on science and technology, a user under the moniker PFritz21 comically critiqued the project as misguided.
'Did Peter Jackson not watch the new Jurassic Park movie?!?!' PFritz21 wrote. 'Once to [sic] start bringing birds back from extinction, you start to think dinosaurs might be a good idea.'

Scientists discover an ancient whale with a Pokémon face and a predator bite

WELLINGTON, New Zealand (AP) — Long before whales were majestic, gentle giants, some of their prehistoric ancestors were tiny, weird and feral. A chance discovery of a 25 million-year-old fossil on an Australian beach has allowed paleontologists to identify a rare, entirely new species that could unlock mysteries of whale evolution. Researchers this week officially named Janjucetus dullardi, a cartoonish creature with bulging eyes the size of tennis balls, in the Zoological Journal of the Linnean Society. Unlike today's whales, the juvenile specimen was small enough to fit in a single bed. Boasting fiendish teeth and a shark-like snout, however, this oddball of the ocean was nasty, mean and built to hunt. 'It was, let's say, deceptively cute,' said Erich Fitzgerald, senior curator of vertebrate paleontology at Museums Victoria Research Institute, and one of the paper's authors. 'It might have looked for all the world like some weird kind of mash-up between a whale, a seal and a Pokémon but they were very much their own thing.' Extinct species was an odd branch on the whale family tree The rare discovery of the partial skull, including ear bones and teeth, was made in 2019 on a fossil-rich stretch of coast along Australia's Victoria state. Jan Juc Beach, a cradle for some of the weirdest whales in history, is becoming a hotspot for understanding early whale evolution, Fitzgerald said. Few family trees seem stranger than that of Janjucetus dullardi, only the fourth species ever identified from a group known as mammalodontids, early whales that lived only during the Oligocene Epoch, about 34 to 23 million years ago. That marked the point about halfway through the known history of whales. The tiny predators, thought to have grown to 3 meters (10 feet) in length, were an early branch on the line that led to today's great baleen whales, such as humpbacks, blues and minkes. But the toothy ancestors with powerful jaws would have looked radically different to any modern species. 'They may have had tiny little nubbins of legs just projecting as stumps from the wall of the body,' said Fitzgerald. That mystery will remain tantalizingly unsolved unless a specimen is uncovered with more of its skeleton intact, which would be something of a miracle. Even the partial skull that allowed the initial identification this week was an astonishing discovery. For an amateur paleontologist, a life-long obsession paid off Janjucetus dullardi was named by researchers after an amateur fossil hunter who doesn't mind its looks in the slightest. 'It's literally been the greatest 24 hours of my life,' said Ross Dullard, who discovered the skull while fossil hunting at Jan Juc Beach. After Wednesday's confirmation of the new species, the school principal walked like a rock star onto campus with 'high fives coming left, right and center,' he said. His friends and family are probably just relieved it's over. 'That's all they've heard from me for about the last six years,' he said. Dullard was on a regular low-tide hunt at Jan Juc the day he spotted something black protruding from a cliff. Poking it dislodged a tooth. He knew enough to recognize it was unlikely to belong to a dog or a seal. 'I thought, geez, we've got something special here,' he said. Dullard sent photos to Museums Victoria, where Fitzgerald saw them and immediately suspected a new species. Ancient whale finds are rare but significant Confirming the find was another matter. This was the first mammalodontid to be identified in Australia since 2006 and only the third on record in the country. Fossils of sufficient quality, with enough of the right details preserved to confirm uniqueness, aren't common. 'Cetaceans represent a fairly miniscule population of all life,' Fitzgerald said. Millions of years of erosion, scavengers and ocean currents take their toll on whale skeletons too. 'It's only the chosen few, the vast minority of all whales that have ever lived and died in the oceans over millions of years, that actually get preserved as fossils,' he added. Finds such as Janjucetus dullardi can unlock insights into how prehistoric whales ate, moved, behaved — and evolved. Researchers said the discoveries also helped to understand how ancient cetacean species adapted to warmer oceans, as they study how today's marine life might respond to climate change. Meanwhile, Dullard planned to host a fossil party this weekend, featuring cetacean-themed games and whale-shaped treats in jello, to celebrate his nightmare Muppet find, finally confirmed.

This Company Claimed to ‘De-extinct' Dire Wolves. Then the Fighting Started

For months, researchers in a laboratory in Dallas, Texas, worked in secrecy, culturing grey-wolf blood cells and altering the DNA within. The scientists then plucked nuclei from these gene-edited cells and injected them into egg cells from a domestic dog to form clones. They transferred dozens of the cloned embryos into the wombs of surrogate dogs, eventually bringing into the world three animals of a type that had never been seen before. Two males named Romulus and Remus were born in October 2024, and a female, Khaleesi, was born in January. A few months later, Colossal Biosciences, the Texas-based company that produced the creatures, declared: 'The first de-extinct animals are here.' Of 20 edits made to the animals' genomes, the company says that 15 match sequences identified in dire wolves (Aenocyon dirus), a large-bodied wolf species that last roamed North America during the ice age that ended some 11,500 years ago.

The company's announcement of the pups in April, which described them as dire wolves, set off a media maelstrom. The ensuing debates over the nature of the animals — and the advisability of doing such work — have opened a chasm between Colossal's team and other scientists. 'I don't think they de-extincted anything,' says Jeanne Loring, a stem-cell biologist at the Scripps Research Institute in La Jolla, California. She and many others say that the hype surrounding Colossal's announcement has the potential to confuse the public about what de-extinction technologies can achieve. Colossal, meanwhile, has taken an increasingly combative tone in addressing criticisms, issuing rapid rebuttals to researchers and conservationists who have publicly questioned the company's work. The firm has also been accused of taking part in a campaign to undermine the credibility of some critics. The company denies having played any part in this. Colossal stands by its claims and insists that it is listening to dissenters and seeking advice from them. 'We have had this attitude of running towards critics, not away,' says Ben Lamm, a technology entrepreneur and co-founder of the company. Colossal ambitions De-extinction is an emerging field that represents the meeting point of several groundbreaking biotechnologies: ancient genomics, cloning and genome editing, ostensibly in the service of conservation. The field has roots in science fiction, with the term seeming first to have appeared in a 1979 novel by Piers Anthony called The Source of Magic. And Michael Crichton's 1990 novel Jurassic Park — itself inspired by ancient-DNA investigations — popularized the possibility that long-dead organisms could be cloned from preserved DNA. There has never been perfect agreement on what counts as de-extinction — such as whether it means cloning exact replicas of extinct species, creating proxies that fulfil their roles in ecosystems, or something in between. Some count the birth of a cloned bucardo (Capra pyrenaica pyrenaica), a type of wild goat, as a first example. The animal's genome was transferred into goat (Capra hircus) egg cells from frozen cell samples taken from one of the last living bucardo specimens in 2000. (The resulting creature died within minutes of birth.) But this pathway to de-extinction isn't an option for most species. DNA degrades over time, and without a sample of carefully preserved DNA, researchers would have to engineer the whole genome. The advent of CRISPR–Cas9 genome editing in 2012 provided another option. Researchers can identify genetic variants that contribute to key traits of extinct animals and edit these variants into cells of living relatives. They can then use that manipulated DNA to create a new animal through cloning. Plans to bring back animals such as the passenger pigeon (Ectopistes migratorius) and the woolly mammoth (Mammuthus primigenius) began to flourish. Even though there was interest among researchers and the public, funding was an issue. 'We had been unable to get really any philanthropic interest in de-extinction,' says Ben Novak, who leads a passenger-pigeon de-extinction effort at the non-profit organization Revive & Restore in Sausalito, California. But in 2021, geneticist George Church at Harvard Medical School in Boston, Massachusetts, who was working with Revive & Restore, caught a break. He teamed up with Lamm to launch Colossal Biosciences with US$15 million in funding, much of which came from venture capitalists. De-extinction of the woolly mammoth would be the firm's flagship project, using elephants as surrogates. Beth Shapiro, an evolutionary geneticist who is chief scientific officer at Colossal, was initially sceptical that there was a strong conservation argument for creating elephants that had key mammoth traits. In 2015, she told Nature that her book on de-extinction, called How To Clone A Mammoth, might have been more accurately titled 'How One Might Go About Cloning a Mammoth (Should It Become Technically Possible, And If It Were, In Fact, a Good Idea, Which It's Probably Not)'. Shapiro turned down an offer to join the company at first, but started seriously entertaining the idea when Colossal expanded its de-extinction ambitions. It began projects to bring back the dodo (Raphus cucullatus), which was wiped out in the seventeenth century, and to restore thylacines (Thylacinus cynocephalus), the Australian marsupials that are sometimes referred to as Tasmanian tigers and that were hunted to extinction in the 1930s. She was especially interested in seeing de-extinction technologies applied to existing endangered species. Shapiro joined Colossal in 2024 as its chief scientist. 'This is an opportunity to scale up the impact that I have the potential to make,' she says. 'Maybe it's a mid-life crisis.' The company, now valued at around US$10 billion, has attracted celebrity investors, including the media personality Paris Hilton and film director Peter Jackson, alongside a handful of leading scientists as staff and advisers. Dire disagreements The dire-wolf project was different from many of Colossal's other efforts because it proceeded quietly. Few people knew about the work until this year, and that irked some researchers. 'They didn't invite any kind of conversation about whether or not that is a good use of funds or a good project to do,' says Novak. Shapiro says the secrecy around the dire-wolf project was designed to generate surprise, and to counter public perceptions that the company overpromises and under-delivers. She also says that the company talked extensively to scientists, conservationists and others about the project and how it should proceed. The firm has not released the full list of edits that it made — 20 changes to 14 genome locations. Fifteen of the changes were identified in two dire-wolf genomes obtained from the remains of animals that lived 13,000 and 72,000 years ago. The genome differs from that of the grey wolf (Canis lupus) by about 12 million DNA letters. Colossal says that other edits, including changes that led to the creatures' white coats and contributed to their large size, were intended to replicate dire-wolf traits using gene variants found in grey wolves. Many scientists say that the coat colour in particular was probably inspired more by the animals' appearance in the fantasy television series Game of Thrones than by reality. 'There is no chance in hell a dire wolf is going to look like that,' says Tom Gilbert, an evolutionary geneticist at the University of Copenhagen and a scientific adviser to Colossal. He says he agrees with other scientists who have argued that, on the basis of what is known about the dire wolf's range, it 'basically would have looked like a slightly larger coyote'. Colossal notes that the coat colour is based on the discovery of variants in two dire-wolf genomes that it says would have resulted in light-coloured fur. According to an update from Colossal in late June, Romulus and Remus weigh around 40 kilograms, around 20% heavier than a standard grey wolf of the same age, and Khaleesi is about 16 kilograms. They live on an 800-hectare ecological preserve surrounded by a 3-metre wall. Colossal plans to make more of the animals, and to study their health and development in depth. It says it will not release them into the wild. Shapiro argued in her 2015 book that forming a wild population is a requirement for successful de-extinction. She nevertheless considers the dire wolves to be an example of de-extinction, and says that creating them will have conservation benefits for wolves and other species. Many scientists disagree. A group of experts on canids that advises the International Union for Conservation of Nature (IUCN) issued a statement in mid-April rejecting Colossal's claim that gene-edited wolves could be considered dire wolves, or even proxies for the extinct species. The statement cites a 2016 IUCN definition for de-extinction that emphasizes that the animal must fill an ecological niche. The work, the group said, 'may demonstrate technical capabilities, but it does not contribute to conservation'. Colossal has disputed this on the social-media platform X (formerly Twitter) saying that the dire-wolf project 'develops vital conservation technologies and provides an ideal platform for the next stage of this research'. Novak says: 'The dire wolf fits the Jurassic Park model of de-extinction beautifully.' The animals have the traits of extinct species and are, to his knowledge, not intended for release into the wild, he says. 'It is clearly for spectacle.' Gilbert, who was a co-author of a preprint describing the ancient dire-wolf genomes, says he is concerned that Colossal is not being sufficiently clear to the public about what it has done. 'It's a dog with 20 edits,' he says. 'If you're putting out descriptions that are going to be so easily falsified, the risk is you do damage to science's reputation.' Lamm rejects the idea that Colossal's messaging undermines public credibility in science, pointing to what he says was an overwhelmingly positive reaction. Loring, who is part of an effort to use stem-cell technology in conservation, says that she sees merit in Colossal's work. It has, she says, changed her views on how to repopulate northern white rhinoceroses (Ceratotherium simum cottoni). But she worries that Colossal's messaging overshadows those contributions. 'It may create an opportunity for us to educate the public,' she says. 'More often, it creates an opportunity for us to be ignored.' To Love Dalén, a palaeogeneticist at the University of Stockholm and a scientific adviser to Colossal, the controversy is 'a storm in a teacup' that detracts from Colossal's achievement. 'It makes me a little bit sad there is this huge debate and angry voices about the common name,' he says. Dogfight Shapiro says she was surprised and saddened by the strength of reactions to Colossal's announcement. 'It was harder than I thought it would be, and the questions were getting meaner and meaner,' she says. But she and Colossal were quick to respond. 'Some of y'all are real mad about this,' she began in a video posted on X in April. 'You can call these animals proxy dire wolves or Colossal's dire wolves. All of that would be correct. We chose to call them dire wolves because they look like dire wolves and reflect the key traits we found by sequencing their genome.' A statement by Colossal to reporters in early April struck a more defensive tone. 'It's obvious most critics would rather complain than contribute,' it said. It asked critics to 'maybe also take a breath and think about what the birth of these technologies means to the future of our planet instead of nitpicking terminology'. Lamm insists that Colossal is willing to listen to scientists' criticisms. He points out that Gilbert is part of its scientific advisory board. But he also questions the legitimacy of some of Colossal's detractors. 'We have a couple of consistent critics that don't have the highest levels of credentials,' he says, 'people who haven't contributed to their fields in quite some time.' Meanwhile, one of Colossal's critics, evolutionary geneticist Vincent Lynch at the University at Buffalo in New York, has accused Lamm and the company of mounting a campaign to discredit him, after Lynch discovered several mostly anonymous web pages and posts questioning his expertise. In a series of posts on X and the social-media service Bluesky, Lynch said he suspects that Colossal and Lamm are responsible for the material. Nature has identified similar posts targeting other critics: Victoria Herridge, an evolutionary biologist at the University of Sheffield, UK; palaeoecologist Nic Rawlence at the University of Otago in New Zealand; and Kristofer Helgen, an evolutionary biologist at the Bishop Museum in Honolulu, Hawaii. Lynch acknowledges that he has no direct evidence that Lamm or Colossal were involved. But he says he thinks that the articles targeting him and others were timed to undermine them just as the company was making major announcements, including those about the dire wolf and a gene-edited 'woolly mouse' that the company says lays the groundwork for its woolly mammoth de-extinction efforts. A Colossal spokesperson said the firm was unaware of the posts aimed at Herridge, Rawlence and Helgen, and became aware of those mentioning Lynch only when he accused Colossal of having a hand in them. The company and Lamm deny any involvement. 'It's unclear to the company who would write critical articles about Vincent Lynch, but given his obsession and aggressive behaviour, the company believes it's safe to assume he may have a few enemies,' says a spokesperson. Lynch says: 'Colossal clearly doesn't know anything about me or my life.' On 19 June, he received a letter from Colossal's lawyers, accusing him of defamation against Lamm and threatening legal action. Lynch says that holding companies and their founders accountable for their words and actions should not be considered defamation. 'It is our responsibility as scientists,' he says. Forging ahead From Colossal's perspective, the dire-wolf announcement was a success. Lamm says that the company tracked thousands of articles and social-media mentions about the achievement using artificial intelligence, and that they are overwhelmingly positive. 'I wouldn't change one thing,' he says. In July, Colossal announced controversial plans to de-extinct moas, a group of giant flightless birds that vanished not long after humans first arrived in New Zealand. And the company remains bullish on its other efforts, predicting that mammoth-like elephants could arrive as early as 2028. Some critics are becoming concerned about how the company will conduct its work in the future, and what the impacts of that might be. In a 2021 opinion piece in Nature, Herridge, who had previously turned down an invitation to serve as a scientific adviser to Colossal, wrote that she felt the company's founders were 'driven by a real desire to help the world'. But after the dire-wolf roll-out, she's concerned about Colossal's approach and its priorities. 'We have a company that is only listening to people who agree with them, who is pushing forward with statements that they aren't backing down from,' she says. This 'is not really where we want to be with a technology that has the potential to change the way our world will look'. Lamm disagrees. 'We happily engage with critics,' he says. 'As scientists, we will absolutely consider new data presented and adapt our hypotheses and conclusions.'
