So it\u2019s fitting that the first animal whose creation Colossal announced was a dire wolf \u2014 an animal that exists, in the public imagination, primarily as a fantasy. Colossal\u2019s advisers include the \u201cGame of Thrones\u201d author George R.R. Martin and two stars of the HBO adaptation, and a press photo showed the animals sitting on the show\u2019s Iron Throne. Many commenters were shocked not by the advancing science of genetic engineering but rather by the revelation that dire wolves were once real animals.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Dire wolves thrived in the Americas for more than 200,000 years, adeptly filling so many ecological niches that their remains have been found from Alaska to Peru. More than 4,000 wolves were pulled from the La Brea Tar Pits in Los Angeles alone. They are understood to have been hunters of the many large mammals that populated the Americas before the arrival of humans dramatically changed the continents\u2019 ecology. They then disappeared alongside their prey, among the earliest victims of what would become an ongoing crisis of human-driven extinction.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Romulus, Remus and Khaleesi began life as gray-wolf cells that were edited, grown into embryos and implanted in the wombs of surrogate dog mothers. The edits, which consisted of 20 modifications on 14 genes \u2014 a small fraction of the 19,000 genes that make up a gray-wolf genome \u2014 were based on comparisons between gray-wolf genomes and those reconstructed from dire-wolf DNA found in ancient tooth and bone fragments. (Gray wolves and dire wolves share superficially similar skeletons, which once led scientists to conclude they were closely related, but they\u2019re actually quite distinct, with evolutionary lineages that diverged millions of years ago.) The resulting animals were larger and fluffier and lighter in color than other gray wolves. The company\u2019s chief science officer, Beth Shapiro, says this is enough to make them dire wolves, if you subscribe to the \u201cmorphological species concept,\u201d which defines a species by its appearance. \u201cSpecies concepts are human classification systems,\u201d she told New Scientist, \u201cand everybody can disagree and everyone can be right.\u201d<\/p>\n<p class=\"css-at9mc1 evys1bk0\">A lot of people disagreed. Calling the pups dire wolves, wrote the evolutionary biologist Rich Grenyer, is \u201clike claiming to have brought Napoleon back from the dead by asking a short Frenchman to wear his hat.\u201d The scientists who specialize in canids for the International Union for Conservation of Nature, a group that monitors biodiversity and maintains lists of threatened and endangered species, responded to Colossal\u2019s announcement with a news release of its own, declaring that \u201cthe three animals produced by Colossal are not dire wolves.\u201d For one thing, they said, there is no way to know if these wolves are good physical proxies for animals no one has seen for 12,000 years. For another, pure physicality ignores the ecology and behavior and culture of the original dire wolf \u2014 the very things that made it one.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Even if Colossal had managed to reproduce the dire-wolf genome, that would be very different from reproducing a world in which a vanished creature might thrive. It\u2019s also different from reproducing all the ways in which those creatures once affected their environment. Shapiro has referred to Colossal\u2019s work as \u201cfunctional de-extinction\u201d \u2014 a concept borrowed from the rewilding movement \u2014 which argues for bringing back the animal activities that maintained an ecosystem, if not the exact animals that once performed them. It\u2019s also a play on the ecological term \u201cfunctional extinction,\u201d which designates species that are still, technically, present in the world but in such starkly diminished numbers they no longer eat or pollinate or otherwise have a meaningful impact on their ecosystems. It\u2019s a term that\u2019s getting more and more play, given that the average size of global wildlife populations declined by 73 percent from 1970 to 2020.<\/p>\n<\/div>\n<p><script async
