The news that Texas scientists have long reintroduced delicate, miserable wolves into the modern world has attracted more attention than just “Game of Thrones” fans.
Researchers at La Brea Tar Pits at the Natural History Museum have been decorated with hundreds of miserable skulls on the wall, but they had questions.
I mean, are they really bad wolves? After all, it depends on how you define it.
“What they created were basically genetically designed grey wolves given genetic traits that could express deeper wolves resembling morphological or physical properties,” said Case Bell, curator of terrestrial mammals at the Museum of Natural History. “The technologies and tools we are developing in this work are incredibly powerful, but I think the terminology used to discuss it is misleading.”
Earlier this week, Dallas biotechnology company Colossal Biosciences announced that it had “depicted” the miserable wolf, sharing news about the birth of three healthy puppies. For more than 18 months, experts out there extracted and sequenced ancient DNA from two disastrous wolves fossils, including a 13,000-year-old teeth in Sheridun Pitt, Ohio and a 72,000-year-old inner earbone in American Falls, Idaho. With that ancient DNA, scientists identified gene mutants endemic to the womb, and then multiplexed gene editing on the genome of the closest living relative of Dire, the grey wolf genome. They used their dogs as surrogates to give birth to three puppies.

Colossal’s Chief Scientific Officer Beth Shapiro said he understands the scientific skepticism that comes with the presentation.
“I got it,” she said. “It’s frustrating to work in paleontology and feel that it’s not effective scientific communication. I wish it would be a little better.”
Southern California has a wolf fossil jackpot that is disastrous compared to other sites, but it is difficult to extract DNA from local samples. Shapiro said she hasn’t tried to collect DNA from local samples in 20 years. Experts say one of the reasons why it is difficult to collect is that LA’s urban landscapes burn in the sun and heat asphalt, which can degrade the ancient DNA buried beneath.
La Brea Tar Pits has the world’s most concentrated, miserable wolf fossils, with the ruins of over 4,000 miserable wolves found on this site. They have lived in the area for at least 50,000 years and disappeared about 13,000 years ago.
“There are no other sites closest to the planet,” said Emily Lindsey, quasi-curator and director of excavation sites at La Brea Tar Pits.
Native to Southern California, Dire wolves, not limited to the region, were highly adaptable and had a very widespread environmental tolerance before the species disappeared about 10,000 years ago, Lindsay said.
The three puppies, Romulus and Remus, born in October and Khaleesi, born in January, currently live in ecological reserves in an undisclosed location spanning over 2,000 acres, host 10 full-time staff who care about and observe them. The reserve is accredited by the American Humane Society and registered with the US Department of Agriculture.
Depending on how you view it, it may now be miserable wolf territory.
In 2016, the International Union for Conservation of Nature published a report focusing on detension, defining it as “recovering a proxies of extinct species that are similar to them in some way, phenotypic, physiological, or ecologically.”
But in the end, she said she really didn’t hang up to what animals are called beyond their names, inspired by the founders of Rome and the “Game of Thrones” show.
“Come on Exantez’s miserable wolves, adhering to the definition the scientific community agreed to a decade ago. Call it on the miserable wolves of Colossal. Call it on the grey wolves, a functional alternative to the miserable wolves,” says Shapiro.
Part of Colossal’s announcement this week included news that it successfully created four clones of the endangered red wolves using new non-invasive cloning technology. Lindsay and Bell said they appreciate Corosal’s work on conserving endangered species species, but they believe that focusing on conservation is a more productive use of resources.
“Some of these technologies have potentially useful uses, especially to prevent the highly endangered species from becoming extinct. I think this would be a much more efficient application of these technologies than trying to bring something similar to an extinct species back to life,” Lindsay said. “If a wolf dies, you don’t want to try and destroy the wolves, right?”
Colossal CEO Ben Lamm said the company would like to combine “reluctant events” with the work it does to protect endangered and species. Other detoxification hopes from the company include the revival of wool mammoths, dodos, tyrasin, or Tasmanian tigers. For Lamm and Shapiro, detension and conservation can work in tandem.
“Conservation and detension are not conflicted with each other. The extinction toolkit should be part of an increase in the ways we have at our fingertips to help endangered species survive,” Shapiro said.
Ram, who sent the kids to the giant team during a Zoom interview with the Times, holding up pictures of Dodos and other extinct animals, said he believes the milestone can encourage more people to pursue careers in related fields.
“Now, the world needs a little hope and I think the world needs more science. Hopefully, we offer a little bit of both,” he said.
And of course, the quotes and references of “Jurassic Park” are thrown down the path of lamm and Shapiro with a spectacular frequency.
“People actually say, ‘Don’t you know what happened at Jurassic Park?’ “‘Did you know what happened there?” “Did you not know what happened there?” “Did you watch the film and learn anything about human hubrism from the film?” They don’t say that. ”
Shapiro added: “People are screaming to us that these are not real miserable wolves. But no one is questioning whether the dinosaurs in Jurassic Park are real dinosaurs. ”
While the debate is still open, Lindsay said he would invite anyone interested in creatures to visit Lovelair’s hole to see some of the “real miserable wolves” they excavated on the site.
“It’s a really cool opportunity – something you don’t get into almost every other city in the world – comes and you can really see the incredible diversity of the massive animals that have lived here until recently,” Lindsay said.
